Four flagship projects, and two more worth a look.
Live
T Poker
A poker study platform and home-game manager, shipped from one codebase
One Expo codebase renders iOS, Android and the live web app, backed by an ASP.NET Core CQRS service over PostgreSQL. The financial core runs in integer cents, and the two stacks carry 6,210 passing tests.

Aegis
A Security Operations Centre where module isolation is enforced by the compiler
Security events flow from ingestion through detection and threat scoring to alerts over MassTransit and RabbitMQ, and reach the dashboard live over SignalR. The whole stack comes up from one Docker command that mints its own RS256 keys.

Released
DeveloperOS
A local-first code workspace that refuses to answer without evidence
It indexes your own projects into a private SQLite FTS5 index and answers with real file and line citations, declining when the index can't support an answer. It ships as one Python package with no runtime dependencies: a CLI, a browser dashboard, an installable PWA or a Windows desktop window.

GRAVITY FLOW
One touch, 150 hand-tuned levels, and physics that had to feel fair
Press and hold to spawn an inverse-square gravity well and pull a lost star home, across 150 data-driven levels in 15 worlds. Built on Phaser 3 in strict TypeScript, with a Vitest suite that pins both the physics and the progression.

About
Engineer by training.
Builder by nature.
I'm a Computer Science graduate, and nearly everything I build comes back to one idea: make the wrong thing hard to express. Money moves in integer cents, so a rounding error has nowhere to live. Module boundaries are compile errors, not code-review habits. A retrieval layer that can't cite a file and a line refuses to answer rather than guess.
That started in C and C++, where nothing is handed to you and the machine is honest about what you got wrong. It carries into the C#/.NET, TypeScript and Python work I do now — each taken from an empty repo to a running system. I'm looking for a junior software development role on a team that ships.

C# carries Aegis's and T Poker's backends, TypeScript their clients, and Python carries DeveloperOS and Job Assistant.
Interface

One Expo codebase renders iOS, Android and the live web app for T Poker — designing for the narrowest target first.
Services & APIs
8bounded contexts
- ASP.NET Core
- Clean Architecture
- CQRS / MediatR
- REST
- SignalR
- RabbitMQ / MassTransit
- JWT / RS256
Aegis moves events across 8 bounded contexts over RabbitMQ, with 0 cross-context references and a retry ladder per endpoint.
Data & State
- PostgreSQL
- SQLite / FTS5
- Redis
- EF Core
- MySQL
- Firebase
SQLite FTS5 powers DeveloperOS’s grounded retrieval; PostgreSQL and Redis back Aegis’s partitioned events and sliding windows.
Delivery
- Docker
- GitHub Actions
- Vercel
- Railway
- Linux
- Git
- Capacitor
- PyInstaller
T Poker's CI runs eight jobs across two languages, each scoped to what a push changes, and Aegis's whole stack — API, frontend, PostgreSQL, Redis, RabbitMQ — comes up under one compose file.
Testing & Tooling
7,061passing tests across five projects
- xUnit
- Vitest
- Jest
- pytest
- Testcontainers
- Playwright
- Claude Code
- Ollama
7,061 passing tests across five projects, weighted toward settlement math, threat scoring, retrieval grounding and level progression.
Think. Build. Ship.
Think: Architecture before implementation.
The hard part of T Poker wasn't the poker UI: it was guaranteeing the money is exact on a phone with no signal, and still correct when the server reconnects.
T Poker
Build: Clean, maintainable systems.
Eight bounded contexts, structured so a cross-module reference fails to compile — verified by a script, not by code review.
Aegis
Ship: Test. Deploy. Improve.
The TypeScript settlement fixtures mirror the C# service case for case, and Aegis comes up from a single Docker command that gates on health.
