I am a Full Stack Engineer with 8 years of experience delivering scalable, intelligent applications by combining modern web architecture with advanced AI systems. I specialize in building AI copilots, LangChain-based agents, Retrieval-Augmented Generation (RAG) pipelines, and vector search infrastructure. I am adept at fusing LLMs with intuitive frontend UX and robust backend services using React, Next.js, Node.js, FastAPI, Java, Go, and cloud-native platforms. I am passionate about delivering human-like experiences through software with deep reasoning, automation, and precision. Throughout my career, I have led architecture and deployment of AI-powered assistants, built comprehensive RAG pipelines, and engineered dynamic tool-calling agents. I have integrated streaming AI responses into dashboards, added observability and tenant-level controls, and enhanced UX with AI-driven feedback features. My background encompasses diverse technical stacks and a strong emphasis on AI integration and performance optimization.

Work Experience

Software Engineer at Herrington & Company, LLC
September 1, 2023 - Present
Led architecture and deployment of AI-powered assistant using GPT-4, LangChain agents, and Pinecone for multi-tenant business dashboards. Built complete RAG pipelines supporting document ingestion, chunking, embedding, and source-based retrieval with real-time OpenAI responses. Developed and maintained full stack web applications using React for dynamic frontends and Node.js + Express for scalable RESTful backend APIs. Implemented robust state management with Redux, integrated third-party APIs, and optimized backend performance via caching, middleware, and async processing. Engineered dynamic tool-calling agents handling question answering, summarization, scheduling, and file parsing. Integrated streaming AI responses into React dashboards via SSE, improving interaction experience by 40%. Added observability for token usage, source trace, latency metrics, and implemented tenant-level rate limits and security controls using PostgreSQL and Redis.
Backend Engineer at Digitant Consulting
July 1, 2023 - September 3, 2025
Integrated semantic search and LLM-enhanced workflows into healthcare and logistics platforms using OpenAI APIs and vector search. Designed and implemented backend services using Java and Go with a focus on high-performance APIs and microservices in distributed environments. Built LLM capabilities via APIs such as OpenAI GPT-4 including intelligent features like document summarization, chatbot workflows, and semantic search for enterprise systems. Migrated enterprise UI to support LLM-based smart form completion, interactive summaries, and suggestion logic. Managed cron-based pipelines for data sync, embedding refresh, and chunk deduplication across knowledge bases. Enhanced UX with frontend AI feedback components, type-ahead prompts, and token-aware query shaping.
Full Stack Developer at Healthfirst
May 1, 2020 - September 3, 2025
Designed secure document Q&A prototype over GPT-based models to enable healthcare staff to ask natural-language queries. Preprocessed sensitive insurance documents for redaction and chunking before embedding into FAISS vector store. Built React-based interface with conversational memory and source-based response validation. Collaborated with legal/compliance teams to enforce PII safety in prompt construction and user input handling.
Frontend Developer at Convex Tech Inc
February 1, 2019 - September 3, 2025
Developed responsive marketing and customer portals using Vue.js and Nuxt.js. Set up unit and E2E test suites with Jest and Cypress, increasing test coverage to 85%. Collaborated with backend team on RESTful API consumption and error handling patterns. Established gitflow and CI/CD pipelines for rapid feature releases. Implemented robust state management with Redux, integrated third-party APIs, and optimized backend performance via caching, middleware, and async processing.
