I completed my Bsc in Computer Science & Engineering from RUET, Bangladesh, and my Masters in Computer Science at Maharishi University of Management, USA. I architect and deliver production-grade AI solutions and scalable SaaS platforms from concept to deployment. My expertise spans building secure, high-performance Retrieval-Augmented Generation (RAG) systems with hybrid search, reranking, and strict citation guardrails, alongside developing full-stack applications with robust observability and maintainability. On the AI/ML side, I specialize in designing and evaluating RAG pipelines - implementing vector search (pgvector), hybrid retrieval, and evaluation dashboards to optimize accuracy, latency, and cost. On the engineering side, I develop multi-tenant applications using React/Next.js and Node.js/TypeScript, backed by PostgreSQL with Row-Level Security, efficient indexing, and Redis/BullMQ for job orchestration. I ensure system reliability through comprehensive monitoring, feature-flagging, and CI/CD-driven deployments. I look forward to partnering with you to architect a solution that not only meets your technical requirements but also advances your strategic business objectives. Best regards, Faruque
