01 / About Me

Every great system begins
with a better architecture

Software Engineer experienced in building scalable microservices with Spring Boot, RESTful APIs, and PostgreSQL. Skilled in Spring Security, JPA/Hibernate, and deploying containerized services using Docker with basic AWS knowledge.

Passionate about backend architecture, testing, and API performance optimization. I've used Kafka for asynchronous communication to improve system throughput by ~30% (self-measured), streamlined Docker/Kubernetes deployments to cut deployment time by ~60% (self-measured), and built secure authentication systems from the ground up.

B.Tech in Computer Science from ABES Engineering College.

Performance

~30% higher throughput (Kafka)

Security

JWT & Spring Security

Cloud-Ready

~60% faster deployments (Docker/K8s)

Featured Projects

Echoe

AI emotional-companion backend on Spring Boot (Java 21) and Docker, backed by PostgreSQL/Supabase, pairing a DeepSeek conversation engine with a Sarvam AI voice pipeline for emotion-aware, voice-first support.

Problem Give people a private, always-available space to talk through emotions by voice or text
Outcome JWT anonymous auth with refresh-token rotation & theft detection, Sarvam AI STT/TTS with emotion-aware tone mapping, real-time crisis-keyword detection with automated helpline surfacing, PIN-protected session vault with tier-based retention, and IP-based rate limiting — deployed on Render

Personal Growth OS

AI coaching platform pairing a Spring Boot modular monolith with a FastAPI RAG engine, bridged through a Resilience4j AI gateway (circuit breaker, retry, timeout) for resilient cross-service calls.

Problem Turn fragmented personal-growth knowledge into grounded, retrievable coaching guidance
Outcome DeepSeek responses grounded in a curated knowledge base, a transcript-to-knowledge-base pipeline (spaCy, semantic chunking, LLM extraction, validation, vector indexing), and a custom retrieval evaluation framework measuring precision/recall
