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.
Featured Projects
