Tathagat T.

I am a Full-Stack MERN Developer and AI Engineer with 4+ years of experience building scalable web applications and integrating AI into real-world business workflows. I do not just build features, I focus on understanding the problem, choosing the right technology, and delivering a solution that is reliable, scalable, and ready for production. What I Bring **1. Full-Stack Development** * React-based web applications and responsive user interfaces * Node.js and Express backend development * MongoDB, database design, and API development * Authentication, role-based access, and scalable architecture * Third-party API and platform integrations **2. AI & LLM Development** * AI-powered chatbots and virtual assistants * Retrieval-Augmented Generation (RAG) * Document-based question answering * Semantic search and knowledge systems * AI summarization and content generation * Embeddings and vector database integration * LLM orchestration and intelligent automation * OpenAI, Azure OpenAI, and AWS Bedrock integrations **3. Production-Ready Engineering** * Cloud deployment on AWS and Azure * Secure and scalable application architecture * API development and integration * Testing, CI/CD, monitoring, and deployment * Data processing and AI pipelines * Applications designed for long-term maintainability **4. Business-Focused AI Implementation** I believe AI should solve a real business problem rather than simply be added as a feature. I can help transform your requirements into practical solutions such as: * Automating repetitive business processes * Building intelligent knowledge assistants * Extracting insights from large volumes of documents * Making information searchable through natural language * Reducing manual effort through AI-powered workflows * Creating intelligent customer or employee-facing applications **5. Healthcare Technology Experience** I also have experience working on healthcare-focused applications where security, privacy, and reliability are critical. This includes: * Healthcare web applications * EHR and healthcare workflows * AI-enabled healthcare solutions * Secure APIs and integrations * Privacy-conscious application architecture ### How I Work I take ownership beyond development. My approach is simple: **Understand → Architect → Build → Test → Deploy → Improve** I communicate clearly, provide realistic estimates and milestones, and keep the development process transparent through regular updates and demos. Whether you are: * Building a new AI-powered product from scratch * Adding AI capabilities to an existing application * Developing a SaaS platform * Automating an existing business workflow * Looking for a full-stack engineer to take ownership of development I can help turn the idea into a **scalable, reliable, and production-ready product**. I am available for both **fixed-price and hourly engagements** and would be happy to discuss your requirements and suggest the right technical approach.
