AI + Full-Stack
Core Specialty
I build scalable backend systems and AI-integrated applications that solve real business problems. With 1+ year of professional experience at an international agency, I specialize in turning complex requirements into clean, performant, and maintainable code — from architecture through deployment.
My background in Electrical Engineering gave me a systems-thinking mindset that shapes how I approach software — every component serves a purpose, every optimization has a reason. I don't just write code; I engineer solutions.
Core Strengths
System Architecture
Designing scalable backend systems from schema to deployment with performance baked in from day one.
AI Integration
Building RAG pipelines, embedding systems, and semantic search that make products genuinely intelligent.
API Performance
MongoDB tuning, Redis caching, and query optimization that measurably cut response times.
Production Deployment
Docker, Nginx, AWS EC2, and GitHub Actions CI/CD — automated, reliable, and repeatable.
"Good software isn't about lines of code — it's about solving the right problem in the simplest way that lasts."
— Development philosophy
Featured Work
Projects that define me
Selected work from real client engagements and personal builds — each solving a distinct technical challenge.
Word Game
Realtime Word Game Platform
A real-time multiplayer word chain game where two players join the same room and compete by entering English words that begin with the last letter of the previous word. The game automatically validates words using a Dictionary API, enforces turn-based rules, and updates scores in real time for a fair and engaging gameplay experience.
Problem
Creating a fair and seamless real-time multiplayer word game with accurate word validation, synchronized gameplay, and automatic rule enforcement.
My Role
Developed a real-time multiplayer word chain game featuring room-based gameplay, live synchronization, automatic turn management, and Dictionary API integration for accurate English word validation and fair scoring.
Impact
Delivered a responsive and cheat-resistant multiplayer experience by automating game rules, eliminating manual validation, and keeping both players synchronized in real time, resulting in smooth, fair, and engaging gameplay.
Storyboard
Social Blogging Platform
A scalable social platform where creators publish stories, build audiences, and engage communities through structured content — built with a focus on performance, real-time interaction, and data integrity.
Problem
Most blogging platforms sacrifice either scalability or developer experience. Storyboard needed to handle personalized feeds, threaded discussions, and async notifications without degrading under load.
My Role
Led the complete full-stack architecture — designed the PostgreSQL schema with cursor-based pagination, built the async job system with Redis/BullMQ for feed generation and notifications, and implemented OTP-based auth with RBAC.
Impact
Production-grade platform handling personalized feeds, real-time notifications, threaded comments, bookmarks, and follower graphs at scale.
Heirloom
AI-Powered Conversational System
An enterprise-grade AI conversational platform with dual-memory architecture — combining short-term session context with long-term semantic memory for deeply personalized, context-aware interactions.
Problem
Standard chatbots lose context between sessions and cannot personalize at scale. Heirloom required persistent memory retrieval across conversations while supporting concurrent multi-tenant sessions without cross-contamination.
My Role
Architected the entire backend: RAG pipeline with OpenAI and Pinecone, dual-memory system (Redis for short-term, vector DB for long-term), automated embedding generation, and isolated multi-tenant session management.
Impact
Semantic memory retrieval pipeline handling concurrent users with isolated conversational contexts and sub-second semantic search responses.
