💼 Work Experience

Nucore Software Solutions (P) Ltd.

Junior Support Executive

June 2023 – July 2023 · 1 month

Dhaka, Bangladesh (BD Office)

Senior Software Engineer - Full Stack & AI

Project: AlpineX AI

Aug 2023 – Present · 2 yrs 3 mos

Led team of 4 engineers to architect production-scale RAG pipeline processing millions of data points from social/web sources using vector embeddings, Pinecone vector database and optimized PostgreSQL schemas.
Built advanced RAG retrieval system with reranking, enabling Web3 AI agents with sub-100ms latency, and shipped 100+ Twitter AI agents using LangChain with OAuth 2.0 authentication and AI reasoning frameworks.
Engineered AWS cloud infrastructure (ECS, EKS, EC2) with Docker containerization and Datadog monitoring and alerting, achieving 99.9% system reliability with 5min incident response time; owned end-to-end delivery from ambiguous requirements to production releases, implementing code review standards and engineering best practices.
