- AI automation — n8n & Make.com workflows, AI agents (RAG chatbots, web-research agents, lead scrapers, email agents), scraping pipelines
- Full-stack development — Next.js/React, NestJS & Node/Express, Python (Flask/Django), Flutter for cross-platform mobile
- Payments & fintech — M-Pesa (Daraja STK Push), card & crypto flows, wallet/ledger design, order state machines & reconciliation
- Algorithmic trading — MetaTrader 4/5 Expert Advisors (MQL4/MQL5): spec-driven, backtested & walk-forward tested
- Beyond code — data annotation, AI image generation & prompt engineering, digital ads and social media management
Selected client and product work (details generalized):
- Custodial synthetic-index trading platform — Next.js + NestJS + TypeScript, PostgreSQL/TypeORM, Docker. Users fund an internal wallet via M-Pesa, cards and crypto, trade digit-option contracts, and can hand trading to a server-side automated bot.
- Mobile-money bundle reseller — Flutter (Android, iOS and Web from one codebase) with a Node/Express backend. M-Pesa Daraja STK Push payments guarded by an order state machine and a money-in/goods-out reconciliation sweep.
- Algorithmic trading EA — MetaTrader 4 and 5 (MQL4/MQL5) automation of a market-structure methodology, built from a deterministic rule spec with backtesting and walk-forward validation.
- Product waitlist apps — Next.js signup front-ends wired to n8n automations.
