About Manasij Haldar

I’m a Data & AI Engineer focused on building intelligent systems that solve real business problems — from internal automation and data workflows to customer-facing AI applications. My work sits at the intersection of AI engineering, backend systems, cloud infrastructure, and product thinking, with an emphasis on solutions that are practical, scalable, and built for production. Over the last few years, I’ve worked across the full lifecycle of AI and data systems: designing LLM-powered applications, retrieval-augmented generation (RAG) pipelines, intelligent agents, recommendation engines, automated ETL workflows, analytics systems, and backend APIs. I enjoy translating ambiguous business requirements into technical architectures that are reliable, maintainable, and aligned with measurable outcomes. My technical stack primarily includes Python, FastAPI, LLMs, SQL, serverless cloud architectures, containerized deployments, and modern API integrations. I’ve also built systems that connect data and AI workflows with operational tools such as CRMs, messaging platforms, ad ecosystems, spreadsheets, and event-driven pipelines — helping teams automate processes, improve decision-making, and create smoother customer journeys. I’m particularly interested in designing complete systems — where data engineering, application logic, automation, and AI capabilities work together cohesively to create business value. Whether it’s building an intelligent assistant, automating a feedback loop, or architecting a scalable backend workflow, I enjoy creating solutions that are both technically strong and genuinely useful in practice. I also hold a patent (No: 550368 / Application: 20••••••••66) for an AI-driven dataset generation pipeline, reflecting my interest in building novel yet practical solutions in applied AI. I’m especially drawn to problems involving AI products, intelligent automation, data platforms, decision systems, and scalable engineering — particularly where thoughtful architecture can make complex workflows feel simple.If you’re thinking through an idea, workflow, or product that could benefit from data or AI — and need help shaping it into something real — I’d be glad to connect.
