Hassaan A.

I’m a senior software engineer who builds and modernizes reliable web, mobile, and backend products. I help teams ship product work when delivery speed, technical quality, and long-term maintainability all matter. My strongest areas are: • React and TypeScript applications, complex product workflows, and API integrations • React Native and Expo mobile apps, including offline workflows, notifications, authentication, media, and releases • Elixir/Phoenix, Python, and Node.js backends, APIs, real-time systems, PostgreSQL, Redis, and GraphQL • AWS infrastructure, Docker, CI/CD, ETL/data pipelines, and production delivery • Practical AI features, workflow automation, and integrations with appropriate human review and controls I am especially useful when a product roadmap is delayed, an existing system needs stabilization or modernization, or a team needs senior ownership of an important feature from technical planning through testing, deployment, and handover. I use AI-assisted development to accelerate research, implementation, testing, and documentation—while keeping engineering judgment, code review, security, and maintainability firmly in place. You can expect clear communication, structured problem-solving, and honest estimates. I work well with product managers, designers, and engineering teams, and I am comfortable taking responsibility for ambiguous technical problems. If you need a senior engineer to build, improve, or stabilize a product, send me the current problem and the outcome you need.
