My Story

Engineering with Passion & Purpose

From competitive problem-solving and ML data modeling to architecting resilient distributed systems.

My Story
Data & Scalability

"Turning complex datasets and high-traffic bottlenecks into seamless digital experiences."

2nd Runner-up • Datathon

Cleaned 500k+ dataset & built ML model with 94% accuracy

Competitive Programmer

Problem Solving with C++ & DSA

Pillar 01

Algorithmic Foundations & Problem Solving

My software journey started with intense problem solving in C++, mastering data structures and algorithmic complexity. This deep foundation allows me to write highly optimized, clean, and maintainable code.

Pillar 02

Microservices & Scalable Backends

Specializing in event-driven architectures with Apache Kafka, Node.js, Next.js Server Actions, and Redis caching. I architect platforms with separated services to ensure high concurrency and fault tolerance.

Pillar 03

Data Analytics & Applied AI

Recognized as 2nd Runner-up at the National Data Analytics Competition by DIU NLP & ML Lab. I processed an extensive 500k+ railway dataset through end-to-end cleaning, feature engineering, and modeling to achieve 94% evaluation accuracy. Today I build production RAG systems with LangChain and vector databases.
