Hello, I'm a Software Engineer at The Flex & base360.ai, based in Bangladesh.

SRE-focused Software Engineer | Cloud & Observability

Work

Tasnimul Mohammad Fahim is an SRE-focused Software Engineer with hands-on experience building observable, fault-tolerant systems for multi-tenant applications handling 15K+ daily transactions. Specialized in cloud infrastructure, deployment automation, and incident management—delivering 10x latency improvements and 80%+ reductions in detection/recovery time. His stack spans Python, Go, TypeScript, FastAPI, PostgreSQL, Redis, and Kubernetes, with deep expertise in Prometheus, Grafana, and SLO-driven reliability practices. He architects micro-frontend systems, implements defense-in-depth security (OAuth 2.0 PKCE, JWT rotation, RBAC), and builds CI/CD pipelines with blue-green deployments. When not engineering reliable systems, he explores algorithmic problem-solving on LeetCode.
