About

5+ years building backends that handle real money, real users, and real consequences. ₦3B+ in transactions processed. 50,000+ active users served. 99.9%+ uptime maintained. Not on side projects, in production, at scale, across fintech, governance, and platforms people depend on daily. What that's looked like: Architecting the core backend for a platform with 50K+ users and 20K daily interactions, 80% throughput improvement, 99.77% uptime. Designing payment infrastructure across Paystack, Interswitch, and Woven that cleared ₦100M+ in peak months without a single incident. Building an e-voting system for 30,000+ participants at one of Nigeria's largest polytechnics, zero downtime, 100% audit accuracy, and elections that went from historically contested to dispute-free. I don't just write backend code. I own the full delivery: API design, database architecture, async task queues, DevOps, cloud infrastructure, and production reliability. I've provisioned and hardened servers on DigitalOcean, Hetzner, AWS, and Linode. I know what breaks at 2am and how to make sure it doesn't. Stack: Python · FastAPI · Django/DRF · PostgreSQL · Redis · Celery · Docker · AWS · DigitalOcean · Hetzner · Paystack · Interswitch Currently building Patchd.dev, an AI-powered security scanner for AI-generated code, built for non-technical founders who ship fast and can't afford to find out what broke in production. Open to senior engineering roles, ambitious freelance projects, and technical co-founder conversations. If you're building something real and need someone who can take backend ownership from day one, DMs are open.

Experience

Patchd.dev

Founder & Engineer

Jan 2026Present · 3 mos · Remote

  • Building Patchd, an AI-powered security scanner that audits AI-generated code for vulnerabilities before it reaches production. Built for non-technical founders who ship fast with tools like Claude Code and Cursor but can't afford a security engineer on day one. 7 early users, 40 scans run in the first 7 days of launch.
  • Designed and implemented a hybrid 2-pass parallel scanning pipeline using async Python, FastAPI, and asyncio.gather, running static analysis and AI-powered vulnerability detection concurrently to minimize scan latency.
  • Built and published a GitHub Action integration to the GitHub Marketplace, enabling developers to run automated security scans on every pull request with zero configuration overhead.
  • Architected the full backend infrastructure: async SQLAlchemy with asyncpg, PostgreSQL, Redis, Docker, Nginx, Cloudflare SSL, deployed on VPS with production-grade reliability.
  • Owned the full product: backend architecture, AI pipeline design, DevOps, frontend (React + TypeScript + Tailwind), and go-to-market positioning.
