About me
a backend & systems engineer who likes to build scalable systems and explore different paradigms in programming .
currently crafting a distributed file system from scratch in golang, because understanding something deeply means building it from scratch.
open to internships and campus placements. if you're building something ambitious I will be glad to be a part of it .
Tech Stack
I'm a generalist at heart who likes to experiment with programs, but here's the core stack i have spent the most my time with .
LLM Gateway Backend
Jakarta EE , MySQL
Implemented a LLM middleware using Jakarta EE for with custom Embedded Tokenizer Engine for token opti- mization, per-client rate limiting via token bucket, automatic provider failover via MySQL.
View DetailsDistributed File System with Content-Addressed Storage
Golang
Serverless peer-to-peer file system in Go . Implements SHA-1 content-addressed storage (CAS) for collision-proof file layout, AES-256-CTR encryption for in-transit data, and gossip-based replication across all connected peers via TCP.
View DetailsFleet Managment and Route Optimization Engine
Spring (Java)
Route optimization engine for multi-stop delivery logistics using Greedy TSP, 2-opt local search, and Genetic Algorithm variants; benchmarked algorithms across 5–20 deliveries. Integrated GraphHopper API with Haversine fallback and circuit-breaker resilience.

Philosophy & Influences
"Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make things worse: complexity sells better."
— Edsger W. DijkstraI focus on the intersection of technical rigor and thoughtful architecture, driven by a need to understand systems at a fundamental level. My approach to engineering is deeply shaped by creators who prioritize building from the ground up and setting high technical standards.
I highly value the low-level exploration of Tsoding, the minimalist, single-header utility of Sean Barrett, and the exceptional technical breadth of Fabrice Bellard.
