Services

What I take on, and what I have shipped doing it.

I am one engineer, so I do not pretend to cover everything. These are the five areas where I have delivered for a paying client and can show you the result. If your problem sits outside them, say so anyway and I will tell you honestly whether I am the right person.

Native and systems software

Desktop applications and performance-sensitive cores, where the work is in the data structures and the memory layout rather than in a framework.

Proof: DICOM to 3D-printable STL, shipped on both platforms

Specifically

C++ cores with native shells on macOS and Windows
Volumetric and geometric processing, mesh extraction, file format work
Multi-threaded pipelines that have to stay interactive
CMake, cross-platform builds, installer and distribution

Computer vision platforms

Not model research. The platform around the models: ingest, synchronise, store, review, annotate, and get a decision out the other end.

Proof: Six-camera inspection platform for a rail fleet

Specifically

Multi-camera ingest over RTSP, ONVIF device control
ffmpeg pipelines, object storage, frame extraction at scale
Annotation workflows on CVAT, label taxonomies, audit trails
Review interfaces that a human actually has to sit in front of all day

Full-stack product engineering

Zero to shipped, or rescue and re-architecture of something already live that has stopped being able to grow.

Proof: Multi-tenant reading platform, live on a client domain

Specifically

Next.js and TypeScript front ends, FastAPI and Node back ends
Multi-tenancy, authentication, roles, per-tenant branding
PostgreSQL schema and migrations, S3, background workers
Monolith to services migrations without a big-bang rewrite

AI features that hold up

LLM and vision features wired into real products, with the grounding, fallbacks and cost control that keep them usable after the demo.

Proof: Fifteen merged pull requests into mem0, an agent memory layer

Specifically

Retrieval and grounding so output traces to real source data
Agentic tool-calling layers over existing systems
Deterministic fallbacks where a model is the wrong tool
Token and latency budgets treated as product requirements

Infrastructure and delivery

Infrastructure as code, containers, pipelines. The part that decides whether shipping on a Friday is routine or frightening.

Proof: Terraform-provisioned AWS and deploy-on-push for a live product

Specifically

Terraform-managed cloud resources, no console drift
Docker, deploy-on-push pipelines, staged environments
On-premise deployment where a client's security posture demands it
Observability and the runbook that makes it someone else's to operate

Mobile and field apps

Software for people who are outside: on a roof, on a site, one hand free and a signal that comes and goes. The constraint is the conditions, not the feature list.

Available now. No client case study to point at yet, so I will walk you through the approach on a call instead of showing you someone else’s.

Specifically

iOS and Android from one codebase, native where the hardware demands it
Offline first: capture now, reconcile when the signal comes back
Camera, GPS, compass and sensor readings bound to a single record
Interfaces that work in gloves, in direct sunlight, at arm's length

Maps, imagery and measurement

Turning a map into a number somebody can order against. Draw on satellite or aerial imagery, get area, distance and layout out the other side, and skip the site visit that was only ever a measuring exercise.

Available now. No client case study to point at yet, so I will walk you through the approach on a call instead of showing you someone else’s.

Specifically

Google Maps, Mapbox, satellite and aerial imagery in the browser and on device
Draw to measure: area, distance, pitch, usable surface, obstruction
Surveys captured on site and assembled into a quote, plan or work order
Centimetre-grade positioning where consumer GPS is not accurate enough

How we would work together

Three shapes, pick the honest one

Fixed-scope project

You know what you need built

Scoped, priced and staged up front. You get milestones with demoable outcomes and a fixed number, not an open meter. Best when the requirements are clear enough to write down.

Retained monthly

The work is ongoing

A set number of days a month on your product. Priorities can move between milestones as you learn. Best for a product already live that needs continuous engineering rather than one delivery.

Discovery sprint

You are not sure it is buildable

One to two weeks, ending in a proof of concept against your riskiest unknown plus an architecture and a plan. Priced small on purpose. You leave with something you own whether or not we continue.

I take a small number of projects at a time, which is the only way the quality above stays true. If I am booked I will say so rather than stretching myself across your deadline.
