I'm Mahadi Hassan, a Senior Backend Engineer with 6+ years designing, building, and operating scalable production backend systems. I work mostly in TypeScript, Node.js, NestJS, and Go, on PostgreSQL, Redis, and Kafka, across microservices, event-driven architecture, and cloud platforms (AWS and Azure).
My work spans fintech, healthcare, SaaS, AI, OTT, manufacturing, and EdTech — multi-country remittance and bank/MFS integrations, AI workflow automation with multi-provider LLM orchestration, OTT media and monetization services, multi-tenant SaaS with Kafka and real-time features, and enterprise ERP reporting. I own the full path: technical design, implementation, integration, deployment, production support, and performance tuning.
Currently I'm a Senior Software Engineer at TulipTech in Dhaka, Bangladesh, working on Sonali Pay (multi-country remittance), VelaCrew.ai (AI operations), PB Play (OTT ecosystem), and EMPATHIKA (enterprise healthcare). I also lead code reviews and mentor engineers. I speak Bengali (native) and English (professional working proficiency).
