(About)

Full Stack Developer who builds and ships AI-powered products end-to-end, from backend architecture to the UI. Spent the last year going deep on agentic AI — building multi-agent systems with LangGraph and Gemini for things like automated content pipelines and a career assistant. Comfortable owning a project from idea to deployment (Node.js, React, AWS, Cloudflare), and always curious to learn whatever the problem needs next.

01

Vantix Ascent

Engineered an autonomous multi-agent content pipeline (Planner → Writer → Reviewer → SEO) using Google Gemini with structured outputs, live SERP intelligence, and Tavily web-grounded citations for fully automated SEO-optimized blog generation. Built an Evaluator-Optimizer loop with automatic revision passes, a parallel Cloudflare Workers image pipeline with Supabase Storage upload, and a configurable workspace system supporting custom personas, multi-language generation, and per-agent prompt overrides. Developed a React frontend with Redis caching, SSE-based live pipeline tracking, Zen reading mode, dynamic Table of Contents, image lightbox, and an admin dashboard for real-time pipeline orchestration.

Joblo

Built an all-in-one AI productivity platform consolidating a resume analyzer, job fit-score calculator, and custom portfolio generator to streamline the career hunt process, acquiring 110+ active users. Engineered Joblo Career Agent, a multi-agent system built with LangGraph and Gemini featuring specialized nodes (Supervisor, Research, Database, and Job Search agents) integrated directly into the web platform to autonomously resolve complex, multi-step career queries. Implemented contextual recall via semantic, episodic, and procedural memory guided by an agent.md config, and automated real-time job scraping/matching using BullMQ, Redis, and Apify. Reduced API response times by 85% (to ∼60 ms) by implementing Redis caching for heavy PostgreSQL queries.
