What I'm looking for

I'm looking to build reliable, maintainable backend and AI systems that can handle growth, especially across fintech, SaaS, e-commerce, and developer tools.

I've co-built EasySpecs.ai, a spec-driven development platform spanning a Vue web app, headless Node.js CLI, and VS Code/Cursor/Windsurf extension. I designed adaptive AI-workstation concurrency, pluggable agent adapters, context-drift pipelines, and bidirectional cloud synchronization.

At Manom, I built a multi-tenant NestJS platform for African SMBs covering invoicing, payments, wallets, payroll, accounting, KYC, analytics, and RBAC. I also built subscription billing, Redis-stream SSE notifications, background workers, Docker Swarm CI/CD, and an AI assistant that works with live business data.

Across fintech, e-commerce, SaaS, and AI products, I've shipped 10+ client projects and production systems using Go, Node.js, Python, PostgreSQL, Redis, Docker, AWS, queues, caching, RAG pipelines, and agent-based workflows.
