About

I’m Sedem Quame Amekpewu, a backend-first software engineer with 5+ years of experience building production systems across AI, fintech, mobile, gaming, and developer infrastructure. I help teams turn complex requirements into reliable APIs, automation, and user-facing products, with recent work spanning LLM evaluation pipelines, RAG/RLHF workflows, FastAPI tool-use sandboxes, Flutter/Unity AR apps, USSD/SMS fintech infrastructure, CRM automation, and CI/CD observability.

Clients bring me in when reliability matters: I’ve improved data operations throughput by 30%, supported payment-critical systems at 99.9% uptime, reduced debugging time by 50% for 200+ engineers, and shipped products used by 20k+ mobile users. I work comfortably across Python, FastAPI, Node.js, React, Flutter, Unity, AWS, PostgreSQL, MongoDB, Docker, Kubernetes, Grafana, and OpenAI integrations.
