@shamiulshopnil
Engineering leader building scalable products from zero to 150K+ users.
BangladeshWhat I'm looking for
I’m an engineering leader with 5 years building and scaling startups from zero to 150K+ users. I scaled an engineering org from 8 to 25+ engineers across 4 cross-functional teams with 95% retention, and I architected microservices delivering 98%+ uptime while reducing API latency by 85%.
I build end-to-end products—like a mental health platform reaching 150K+ users with telco/fintech integrations, real-time session booking with WebSocket-based slot management, and an Riri AI chatbot with LLM integration. I’m at my best in async-first distributed teams, where I establish engineering excellence through 85%+ test coverage, CI/CD, Prometheus/Grafana monitoring, and incident response playbooks.
