I architect backend systems that handle real-world scale. From high-throughput APIs to blockchain integrations and AI-driven automation, I build the infrastructure layer that products depend on to grow. With production experience across Node.js and Python, I've designed and shipped backend systems for startups, agencies, and established businesses. My focus is always the same: clean architecture, strong security, and systems that don't break when traffic spikes or requirements change. Backend Architecture and API Development I design RESTful APIs and microservice architectures using Node.js, Express.js, Python, and FastAPI. Every system I build follows clear separation of concerns, proper error handling, and thorough documentation. I handle database architecture across PostgreSQL, MySQL, and MongoDB, with a focus on query optimization, indexing strategies, and schema design that supports long-term growth. Authentication, role-based access control, JWT implementation, and secure data handling are built into every project from day one. Blockchain and Payment Infrastructure I integrate blockchain functionality into backend systems using Ether.js and Web3 libraries, alongside traditional payment gateways like Stripe, M-Pesa, and MTN MoMo. Whether you need smart contract interaction, wallet integration, or multi-provider payment flows, I build payment infrastructure that is reliable and secure in production. AI-Driven Systems This is where my work goes beyond standard backend development. I build intelligent backend systems that integrate LLM APIs, machine learning models, and data processing pipelines directly into production architecture. Recently I built an agentic job matching platform with concurrent API orchestration, intelligent scoring, and real-time recommendations served through a high-performance FastAPI backend. I design AI workflows that are production-ready, not just prototypes. How I Work Every project starts with understanding the business problem, not just the technical requirements. I communicate clearly, ship on schedule, and write code that your next developer can read and extend without a walkthrough. I'm comfortable leading backend architecture from scratch or stepping into an existing codebase and making it better without breaking what already works. Tech Stack: Node.js, Python, FastAPI, Express.js, PostgreSQL, MySQL, MongoDB, Redis, Ether.js, Web3, Docker, Git, CI/CD Collaboration: Slack, Microsoft Teams, Jira, Trello, Asana, ClickUp If you need a backend architect who can own your entire server-side infrastructure and deliver systems that are fast, secure, and intelligent, let's talk.
