Open to engineering roles · Full-Stack Engineer

I build complete product systems, end to end.

Full-stack engineer with a focus on applied AI. I ship the whole system: a Laravel SaaS with a custom analytics engine, native trading software, and an LLM-driven content platform. Backend, frontend, and the integrations between.

Riskeys

Trading-analytics SaaS

Founder & lead engineer

riskeys.trade

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.

  • Custom analytics engine: six metric computers with partial-close grouping so a multi-leg exit counts as one trade.
  • Broker-clock normalization detects each broker's UTC offset and re-bases every timestamp before time-bucketing.
  • Seven behavioral pattern detectors (overtrading, revenge trading, discipline drift) on a clean interface/DTO contract.
  • Real-time trade sync: the client pushes account state as JSON every 100ms; the server reconciles open and closed positions.

Riskeys EAs

Native MetaTrader software

Sole developer

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.

  • Custom on-chart GUI framework from scratch: 30+ classes for windows, panels, buttons and event handling.
  • WinAPI HTTP layer plus a JSON parser in MQL for token auth, trade upload and screenshot POST.
  • Prop-firm rule engine validating position sizes and daily limits from per-broker JSON configs.
  • MT4 and MT5 kept in parity through a documented dual-repo git workflow.

03AI / LLM

ContentOS

AI content platform

Architect & builder

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.

  • Dual-LLM split: Anthropic Claude for publishable copy, local Ollama for code analysis that never leaves the machine.
  • RAG pipeline ingests a codebase, chunks and embeds it with pgvector, and extracts marketing-safe product claims.
  • Automated claim and compliance checker validates every generated piece against a policy database.
  • MCP-based agent fulfillment: the app queues work, an agent pushes it (e.g. to Klaviyo).

  • Execution Bridge

    Order-routing service

    A NestJS service that routes orders from the trading client to an exchange API and polls positions back, isolated behind HTTP.

    NestJS · Fastify · Prisma · PostgreSQL · BullMQ · Redis

  • Telegram Bridge

    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.

  • Remotion Renderer

    Programmatic video

    Headless React/Remotion rendering of nine compositions: daily recaps, trade replays and social clips in widescreen, square and story formats.

  • Shopify Storefront

    Heavily customized Dawn theme

    A custom storefront on Shopify's Dawn theme with bespoke product, pricing and affiliate sections.
