AI product development
Build AI products around real legal work.
I help legal-tech founders and product teams build new applications, add AI features and improve existing platforms. I connect the interface, models and tools, with permissions, human review and tests your team can maintain.

Prepare a status update for matter DEMO-104.
Retrieve matter context
Read the permitted matter record.
Source: matter DEMO-104
Prepare a status update
Draft from the recorded facts.
Tool: draft composer
Check what is missing
The next review date is missing.
Flag the gap; do not invent a date
Human approval
Check the source, fill the gap and approve the draft.
Source linked. Missing detail flagged. You decide.
Fictional data: a user requests a status update for matter DEMO-104. The product reads permitted case context, drafts from the record and flags a missing review date. A person checks and approves the draft before any message is sent and recorded.
My approach
Build the product around the work.
Users need source material, a place to review drafts and a clear next action. I build the interface, backend and integrations around that task, whether you are creating a legal-tech product or improving an existing application.
Before building, we agree what AI can prepare, what people approve and what happens when evidence or a connection is missing. Those decisions shape access, testing and release checks. Your maintainer receives the code, operating notes and known limits.
Your starting point
New product or existing codebase.
Start with an idea, product or prototype. Legal-tech and other software teams can scope one useful release around their users, data and existing tools.
You have an idea
I turn the user task into a build plan, test the uncertain parts and develop the first usable application.
You have a product
I add an AI feature within your existing interface, accounts and data permissions, connecting it to the systems your team already uses.
You have a prototype
I review the code and model behaviour, repair weak integrations and close the testing, security and deployment gaps before release.
What I build
The engineering behind a usable AI product.
Build a complete application, add one feature or repair an existing system. These ten capabilities cover the product, model and integration work; scope determines which you need.
Complete AI applications
I build the product around the AI task: user interface, accounts, backend, stored work and deployment. Users can review results and continue their work in the same application.
Under the hood: Application APIs, authentication and data storage connect to the model layer, with loading, error and recovery states.
Example scope: A legal research workspace that organizes selected sources into an editable report.
AI features in existing products
I add search, drafting, classification or assistance to the product your users already know. The feature follows existing permissions and fits the surrounding workflow.
Under the hood: I connect existing APIs and account context, isolate the new behaviour and plan a release that can be rolled back.
Example scope: A drafting assistant inside an existing case-management application.
LLM applications and copilots
I build conversational tools that help people ask questions, prepare work and turn free text into usable records. The interface makes review and correction part of the task.
Under the hood: Versioned prompts, managed conversation context and validated response formats keep model behaviour inspectable and testable.
Example scope: A legal request copilot that turns a conversation into an editable request record.
RAG and knowledge search
I connect answers to approved company knowledge, with references people can inspect. When the available material cannot answer the question, the system makes that gap visible.
Under the hood: Retrieval-augmented generation (RAG) combines permission-aware document ingestion, indexing, retrieval and source checks; content updates are part of the design.
Example scope: An internal assistant that answers policy questions using documents the employee can access.
Document understanding and extraction
I turn documents into information your team can review and use: summaries, extracted fields and records linked to their source material. Unclear or missing values go to review.
Under the hood: Parsing, model extraction and field validation feed your application, retaining source references and routing exceptions to a person.
Example scope: An intake document converted into a draft case record for staff to check.
AI agents and agentic workflows
I build agents that gather context, use approved tools and prepare the next step in a defined workflow. You set the allowed actions and where a person must approve.
Under the hood: Tool permissions, step limits, validated inputs and execution records bound the agent’s actions and support investigation when a step fails.
Example scope: An agent that retrieves matter context and prepares a case update for review.
AI workflow automation
I connect incoming work to the next operational step: classify a request, prepare a record, route it for review and update the agreed system. AI handles the parts that need interpretation.
Under the hood: API and event integrations coordinate jobs, retries and duplicate prevention, with human decision points for consequential actions.
Example scope: An emailed request routed to the right team with a draft response and a task record.
Generative content interfaces
I build tools for producing text, images or structured content with controls for the person using them. Users can provide context, compare results, edit and approve what they keep.
Under the hood: Generation APIs connect to templates, format checks and review steps; model and asset handling follow the project’s data requirements.
Example scope: A content workspace that prepares drafts and image variations for editorial review.
AI evaluation and monitoring
I define useful and unacceptable results, then test the system against representative tasks and difficult cases. Operational signals help your maintainer spot failures and changes in behaviour.
Under the hood: Repeatable evaluation cases compare prompt, model and retrieval changes; traces track failures, response time and usage costs.
Example scope: An answer test set that checks evidence use, missing information and restricted requests before release.
AI reliability and hardening
I review an existing AI build and address the gaps preventing a dependable release. That can mean correcting retrieval, fixing failed jobs, tightening access or making failures recoverable.
Under the hood: I reproduce failures, review application and tool boundaries, add regression checks and document remaining risks and release conditions.
Example scope: A prototype assistant repaired so it stops on missing evidence and recovers from a failed connection.
Delivered work
Legal intake, connected from request to review.
I built the application and services that bring calls, emails and documents into a reviewable intake record. AI prepares the information and proposed next step; a person reviews and approves the action.
Read the intake case studyWhat I delivered
- Intake interface and document processing in Node.js and Python/FastAPI.
- Permitted email and file access through Microsoft Graph and SharePoint.
- Separate preparation, approval and execution, with an action record.
How I deliver
From requirements to release.
Each stage has a concrete output and a review point. We agree the scope and acceptance checks before implementation, then use working software to assess progress.
- 01
Define the useful release
I map the user task, data access, integration limits and the work required.
You receive: A release brief with acceptance checks.
- 02
Build the product around the model
I connect the interface, backend and tools. You review behaviour, permissions and human decision points.
You receive: A connected product for your review.
- 03
Test beyond the happy path
I test wrong inputs, missing evidence and failed APIs, then check response times and model costs. Known limits stay visible.
You receive: A release candidate and repeatable tests.
- 04
Deploy and hand over
I deploy within the project's access boundaries, check the release and walk the maintainer through rollback and operating responsibilities.
You receive: A deployed release and handover pack.
What you get
What you receive at handover.
Code, tests and operating notes help your team manage the next release. We agree the outputs and responsibility for running the product before handover.
Working application and source code
The agreed release in your environment, with application code, integrations, configuration and setup instructions in the named repository.
Repeatable AI output tests
Representative tasks and failure cases, with expected behaviour and instructions for checking future model, prompt or retrieval changes.
Logging and alerts
The agreed failure, response-time, usage and cost signals, with alert conditions and a named operating owner.
Designed failure behaviour
Implemented stop conditions, retries, alternative paths and human escalation for the failures identified in scope.
Release and rollback runbook
Deployment steps, release checks, rollback instructions and a starting point for investigating incidents.
Risk notes
Data exposure, model limitations, misuse cases and unresolved dependencies, with mitigations or an explicit decision to accept the remaining risk.
Architecture notes
How the application, models, data and tools connect, why key choices were made and where access boundaries apply.
Handover walkthrough
A walkthrough with the maintainer covering the code, tests, release process, known limits and responsibility for ongoing operation.
I confirm the final list before building, based on your product and operating environment.
Why work directly with me
Work directly with the engineer building it.
I scope the work, write the code and review progress with you. Product decisions stay connected to the implementation, from the first integration to handover.
Solo engineering, with scope and availability agreed upfront. Ongoing support is scoped separately.
Direct technical ownership
Your questions reach the person writing the code. Decisions stay connected to the implementation.
AI and security, built together
Data access, tool permissions and failure paths are part of the build from the start.
A product your team can maintain
Code, tests and operating notes make the next release easier to own.
Before we build
Clear scope. Clear expectations.
Can you build a legal-tech product or add one feature?
Both. I build legal-tech applications or add AI to an existing product, including its interface, backend, permissions and integrations. Broader product engineering covers the surrounding platform and work outside legal.
Can you use our existing code and tools?
Yes. I review the code, APIs and access first, then agree what to reuse, repair or replace before building.
Which model will you use?
I choose against your task, output quality, speed, cost and data requirements. That may mean a model API, an open model or retrieval; fine-tuning needs a clear reason.
How do you protect sensitive data?
I define permitted data, providers and actions, then build access controls and review points around them. My AI and data governance work covers the technical controls; your specialists own legal and compliance decisions.
What will it cost, and how long will it take?
You receive a written scope, estimate and acceptance checks before the build. Code quality, data access and integrations shape the schedule; scope changes are agreed before extra work.
What do we receive at handover?
Project code, setup instructions and operating notes in the agreed repository. Rights, licenses and responsibilities are set in the contract; third-party terms still apply.
Do you support the product after launch?
Maintenance and improvements can be scoped separately, with agreed availability and responsibilities. Round-the-clock support is not included.
Can we start small?
Yes. Start with one feature or AI workflow, review the result and decide on the next release.
