Fintech · Founder & lead engineer
Trading-analytics SaaS
A Laravel platform that turns raw MetaTrader trade history into honest analytics. Traders run a custom client that streams their account state in real time; the backend computes performance, normalizes broker time, and surfaces behavioral patterns.
Fintech · Sole developer
Native MetaTrader software
The desktop side of Riskeys: trading-risk software written natively in MQL4 and MQL5. An on-chart panel for position sizing and journaling, talking back to the platform over a hand-built HTTP layer. Not an auto-trader; the trader always decides.
Infrastructure · Builder
Order-routing service
A NestJS service that routes orders from the trading client to an exchange API and polls positions back, isolated behind HTTP.
Infrastructure · Builder
Signal relay & account linking
Two Python services: a Telethon listener that relays channel signals to the API with catch-up, and a bot that links Telegram users to dashboard accounts.
Infrastructure · Builder
Programmatic video
Headless React/Remotion rendering of nine compositions: daily recaps, trade replays and social clips in widescreen, square and story formats.
Infrastructure · Builder
Heavily customized Dawn theme
A custom storefront on Shopify's Dawn theme with bespoke product, pricing and affiliate sections.
Fintech · Architect & builder
Duolingo-style trading education platform
A behavioral trading-education platform built from Riskeys' 140-day curriculum, turning a static course into an interactive, gamified learning product with its own product-design pipeline from research to shipped MVP.
AI · Architect & builder
AI content platform
A Next.js + Supabase system that generates on-brand marketing content grounded in real product data. A dual-LLM design keeps publishable copy in the cloud and source-code analysis fully local, with an automated checker that blocks false claims before anything ships.
AI · Sole developer
Persistent memory layer for an AI agent
A graph-based memory system for a personal AI agent: entities, relations and aliases persisted in SQLite, recalled automatically into every prompt via a submit-time hook. Built with an actual test suite, not just scripts.
Infrastructure · Architect & builder
LLM-agnostic operating layer for the business
The organisational layer that lets any AI agent understand and operate across No Brainer HQ's ventures: department charters, registries, and an operating model expressed as structured, agent-readable documents instead of tribal knowledge.

Website concept, legal services
An interactive, multilingual, multi-page website concept for a law firm in Amsterdam.
Applied LLM work: integration, RAG & agentic workflows, not model training.
From database schema to deployed UI.
Domain depth in trading and risk.
The glue that makes systems talk.
Tools I work with
Beyond the systems I build, here is how I actually operate: fast on ideas, driven to ship, comfortable when the path isn't fully mapped out yet.
Comfortable with ambiguity, iterates fast on ideas, and pushes back when something doesn't add up.
Drives projects toward execution, results-oriented, sets a high bar and expects the same from collaborators.

No Brainer HQ
Map where AI and automation create real value across a business, then design and build the system myself: LLM integration, RAG pipelines, agent memory, and the connective infrastructure between AI models, data, and business software. Recent work: ContentOS (AI content platform) and Hermes Graph Memory (agent memory layer).
2022 · Present
Riskeys
Built a trading-analytics SaaS end to end: a Laravel backend with a custom analytics engine, native MQL4/MQL5 desktop software, and the integration layer connecting them. From schema to deployment, sole technical owner.
2014 · 2022
Independent / client work
Built and integrated workflow-automation systems across e-commerce and digital services: APIs, webhooks, payment flows, and operational tooling that reduced manual work for several ventures and clients.
