About me
Intro
Most startups don't struggle because they lack features, they struggle because their backend systems don't scale, break under load, or become impossible to maintain. That's where I come in. I'm a Backend Engineer with 3+ years of experience building and optimizing production systems across fintech, real estate, and professional networking platforms. I specialize in designing APIs and backend architectures that are fast, reliable, and built to handle real-world usage not just demos. I work primarily with Python (FastAPI, Django) and PostgreSQL, and I've built systems that include: Secure fintech APIs handling authentication, transaction flows, and Paystack integrations with rate limiting and fault toleranceScalable feed and search systems with Redis-backed caching and personalization logicReal estate platforms with geo-search, payment flows, and multi-role dashboards (landlords & tenants)Event creation app with collaboration flow, and planing with Ai Beyond just writing code, I focus on system performance, scalability, and long-term maintainability: Reduced bottlenecks using Redis caching and async processing (Celery)Designed resilient systems using circuit-breaker patterns and background workersBuilt and managed CI/CD pipelines and cloud infrastructure end-to-end I don't just build features — I build systems that don't break when users show up. Currently open to remote backend engineering roles and contract opportunities where I can help scale systems, improve performance, or bring structure to growing architectures.
