Unreliable systems, slow APIs, and brittle integrations quietly kill products. I've seen it firsthand, and I build the kind of backend infrastructure that doesn't let that happen. Over the past 3+ years I've worked on fintech platforms, POS systems for pharmaceutical companies, and cloud-native applications that real people depend on daily. The problems I solve aren't always glamorous duplicate transactions, race conditions, failing queues, APIs that break under load but getting them right is what separates a product that works from one that doesn't. That's the work I genuinely enjoy. What I'm good at: → Payment integrations (M-Pesa Daraja, banking APIs) built to be reliable — idempotent, resilient, and hard to break. I redesigned one platform's payment pipeline from scratch and took their transaction success rate from 60% to 95%. → Microservices with Spring Boot API gateways, role-based access, async messaging with RabbitMQ → Full-stack builds with Next.js/React on the front, Spring Boot, Nest.js, or Flask on the back → Cloud infrastructure on AWS and GCP, containerized with Docker Tech stack: Java (Spring Boot), Python (Flask), TypeScript, Next.js, Nest.js, React, PostgreSQL, MongoDB, Redis, RabbitMQ, Docker, AWS, GCP I write tests, communicate proactively, and ship in small working increments no big-bang surprises at the end. I'm based in Nairobi (EAT/UTC+3) and I overlap well with US, EU, and UK hours. If you're building something and need a backend engineer who'll actually care about how it works, lets work together.

Software developer, 4 years experience. I build APIs, backend systems, and platform infrastructure for startups. Most of my work involves Node.js, TypeScript, Python and Django when the project calls for it. I'm comfortable with AWS, Docker, REST APIs, authentication systems, payment integrations (Stripe), real-time features with WebSockets, database design with PostgreSQL and MongoDB. I've also set up CI/CD pipelines, deployed to AWS, and monitoring using Prometheus and ELK Stack. Can do frontend as well (React/Next.js/Svelte). Recent work includes a chat system with message editing and replies, API maintenance handling thousands of daily requests, and backend systems for a social platform. Clean, documented code. Available for both short contracts and longer engagements. I work EU and US timezone hours from Nairobi. Clear communication, no disappearing. If something's blocked, I'll tell you. Happy to chat about your project.
