Skills & Expertise

A comprehensive overview of my technical skills and experience across different domains

Backend Development

Java, Spring Boot/Cloud

Built everything from e-commerce platforms to admin dashboards and mobile app APIs. Yeah, I've wrestled with microservices complexity too.

Node.js, Express/Nest.js

When I need something up and running fast, or when the team prefers JavaScript across the stack.

Frontend Development

React, Next.js

From internal management systems to my own side projects. Actually enjoy making things responsive and user-friendly.

Tailwind CSS, Shadcn/ui

My go-to combo for building modern UIs quickly. Love how Tailwind keeps things consistent and Shadcn gives me beautiful components out of the box.

AI & Agent Engineering

LangChain, LangGraph

Building AI agents and multi-agent systems. Designed a LangGraph-based multi-agent pipeline for complex task orchestration.

Prompt Engineering, RAG

Crafting reliable prompts and retrieval-augmented generation pipelines. Implemented vector search with Pinecone for semantic content discovery.

Infrastructure

PostgreSQL, Redis

PostgreSQL is my go-to database, from schema design to query optimization and performance tuning. Redis for caching and session management when speed is critical.

System Design, Message Queues

I think about scalability from day one, not as an afterthought when things break.

Always Learning, Always Growing
