Transforming ideas into intelligent solutions, building at the intersection of software engineering and artificial intelligence.
01 · AboutEngineer first, researcher always
Building with intention
I'm a full-stack software developer and AI researcher specialising in decision support systems1 and collective decision-making models. I love building APIs, desktop and server software, with a focus on creating innovative solutions while fostering collaborative environments.
I'm passionate about AI and its integration into preexisting systems, particularly generative AI, model distillation2, and consensus-building technologies.
1Systems that help groups decide, not just dashboards that watch them.
2Big-model judgement, small-model budgets.

02 · Process
Database to pixel
One engineer, every layer- 01
Database to pixel.
One engineer across the whole stack, so nothing gets lost in a handoff. The schema and the button were designed in the same head.
- 02
No black boxes.
Every layer is code I wrote and can explain, from the migration to the prompt. Typed, lean, readable — fast because there's nothing extra in it.
- 03
AI where it earns its place.
Models get measured against a baseline and wired with a fallback. If a plain rule does the job, the rule wins.
- 04
Built to be inherited.
Tested, documented, boring in the right places. The next engineer — or me, two years on — can pick it up cold.

What I build
Full stack, integrations, architecture- 01
Full-stack products
From the schema to the last pixel, with one person accountable for all of it.
- 02
Integrations & APIs
The tools you already pay for, talking to each other — so data moves without anyone copy-pasting it.
- 03
Systems design & architecture
The diagram before the code: boundaries, data flow, failure modes, and what it costs to run.
- 04
AI & LLM features
Retrieval, agents and evaluations wired into real workflows — and measured against a baseline.
- 05
Data pipelines & dashboards
Ingest, clean, score, show. Pipelines that run on schedule and dashboards people actually open.
- 06
Technical advisory
A senior second opinion on a codebase, a plan or a hire, with the findings in writing.
