Engineering at the Intersection of Web & AI
From full-stack product delivery to production-grade GenAI systems
Full-Stack & GenAI / LLM Engineer
I'm a results-driven engineer with 5+ years of experience building scalable web applications, intelligent AI agents, and RAG-based systems. My work spans the full lifecycle — system design, CI/CD pipelines, and integrating LLMs (GPT, Anthropic, Gemini) into production environments.
At Highbrow Technology, I've architected data-dense B2B SaaS platforms, built autonomous tool-calling agents with LangChain & LangGraph, and led GenAI/LLM project coordination across technical and non-technical stakeholders.

Full-Stack Development
Scalable, data-dense web applications built end-to-end with React, Next.js, Node.js, and Python — from system design to production deployment.
AI Agents & LLM Integration
Production-grade chatbots and autonomous tool-calling agents using LangChain & LangGraph with stateful memory and Human-in-the-Loop workflows.
RAG Architecture
Retrieval-augmented systems with PostgreSQL and Pydantic validation for efficient semantic search and structured data retrieval.
CI/CD & E2E Testing
Reliable delivery pipelines with GitHub Actions, Docker, and AWS, safeguarded by critical-path Playwright & Cypress test suites.
Work Experience
My professional journey at Highbrow Technology Inc.
System Analyst
Jul 2025 – Present- Architected a complex, data-dense B2B lead management workspace using React, TypeScript, Anthropic API, PostgreSQL, Apollo GraphQL & Blueprint.js to configure targeted sales campaigns.
- Built production-grade intelligent chatbots and autonomous tool-calling agents using LangChain & LangGraph with stateful memory, reducing manual workflows.
- Designed RAG systems with PostgreSQL and Pydantic validation for efficient semantic search and structured data retrieval.
- Engineered modular pipeline views with Recharts analytics and a 3–4s live polling loop for real-time processing updates.
- Authored critical-path E2E user-workflow tests with Playwright in the CI/CD pipeline, and built a Surveillance & Analytics Dashboard with Flask APIs, object detection & LPR (MongoDB).
Software Engineer
Jan 2024 – Jun 2025- Contributed to LLM training pipelines for X-AI by engineering custom, interactive real-world 3D applications and data visualisation tools in JavaScript.
- Optimised containerised TypeScript applications for Gemini (Google), achieving high reliability through comprehensive Cypress & Playwright E2E and unit test suites.
- Designed and deployed multiple dynamic, browser-compatible React pages enhancing system responsiveness and scalability across production deployments.
Associate Software Engineer
Jul 2020 – Dec 2023- Developed robust React & Next.js front-end components for an AI-powered Applicant Tracking System and recruitment platform.
- Engineered a bulk email marketing application with Node.js/Express.js RESTful microservices and Mongoose for targeted campaign management at scale.
- Integrated front-end components with backend systems through cross-functional collaboration, ensuring API contract alignment.
- Authored technical specifications, code annotations, and user manuals supporting unit testing and team knowledge transfer.
