01 / About Me

Engineering with reliability, clarity, and scale.

Effective backend software engineering is about clean domain boundaries, defensive data validation, thread-safety, and building systems that remain dependable under real-world traffic.

Let's discuss engineering opportunities

I am a 4th-year Computer Science undergraduate (graduating 2027) focused on building enterprise-grade backend infrastructure. My foundation centers on Java, Spring Boot, Spring Security, Redis, and relational database modeling with PostgreSQL. Having solved 377+ algorithm problems and led a 6-engineer team to a Top 50 national finish at the Smart India Hackathon, I approach system development with an analytical, fail-safe mindset.

Architect for Failure

I design distributed state, fallbacks, and circuit breakers knowing network partitions and traffic surges happen.

Security at the Boundary

Role-based access control (RBAC), stateless JWT authentication, and strict input validation built right at the filter level.

Data Integrity First

Normalized relational schemas, indexed queries, and ACID transactional boundaries that protect business consistency.

Applied AI Integration

Integrating LLM inference (Groq LLaMA 3) into production workflows with structured prompt pipelines and error budgets.

02 / Technical Stack

Pragmatic tools. Rigorous fundamentals.

Every tool in my stack is chosen for performance, type safety, and real-world backend scalability.

03 / Selected Work

Engineered with architectural depth.

Real-world projects with defined problem statements, evaluated trade-offs, and clean implementations.

Distributed Systems Spring Boot • Redis

Distributed Rate Limiter Service

High-throughput API rate-limiting middleware built in Spring Boot and Redis to mitigate traffic spikes and prevent cascading service outages. Engineered with Redis Lua scripts for atomic token evaluation under sub-5ms latency across horizontally scaled instances.

GitHub

Enterprise Backend Live • Spring Boot • React

E-Commerce Platform

Full-stack store with Spring Boot, React, JWT, and Google/GitHub OAuth 2.0. Implements 3-tier RBAC, ACID-compliant checkout, a normalized PostgreSQL schema, and a Groq-powered customer support chatbot.

04 / System Design in Action

Concepts tied directly to working implementations.

System design is not abstract trivia — here is how specific principles were applied across my actual codebase.

Distributed Rate Limiting & State Synchronization

Implemented atomic Redis Lua scripts in the Distributed Rate Limiter to execute token deductions in a single roundtrip, preventing race conditions across multi-instance clusters.

Stateless Authentication & RBAC Filter Chains

Engineered Spring Security filter chains with stateless JWT validation and 3-tier Role-Based Access Control in the E-Commerce Backend, protecting customer, seller, and admin routes.

Relational Schema Normalization & ACID Transactions

Modeled 3NF normalized PostgreSQL entities with foreign key constraints in the E-Commerce Backend, eliminating N+1 query overhead using explicit JPQL JOIN FETCH clauses.

Sub-millisecond In-Memory Caching Strategies

Configured TTL-based Redis key invalidation to cache high-frequency rule lookups and token buckets, reducing backend database load under heavy concurrent bursts.

Applied LLM Prompt Pipelines & Error Budgets

Integrated high-speed Groq LLaMA 3 inference into SmartHire and AlgoPush with structured JSON response parsing and fallback retry strategies.
