Computer Science undergrad • OSS Contributor

I'm a Computer Science student who genuinely enjoys building systems from the ground up especially the data models, edge cases, failure handling, and performance trade-offs.

Backend is where I feel most at home designing APIs, structuring databases carefully, and thinking about scalability before it becomes a problem.

Focused on backend systems, database design, and architecture rather than demo projects.

I care about understanding why systems behave the way they do not just making features work.

Currently looking for Summer 2026 internships where I can learn from strong engineers, contribute meaningfully, and grow into a solid backend developer.

• Writing backend code that is maintainable, observable, and resilient
• Designing relational schemas with proper indexing and constraints
• Clear API contracts and predictable system behavior
• Security, performance, and operational visibility from day one
• Shipping real systems — not just tutorial demos
• Understanding trade-offs between consistency, latency, and scalability

• Building microservices in Go to better understand distributed systems behavior
• Learning Spring Boot and enterprise backend patterns
• Strengthening system design fundamentals
• Contributing to open-source projects when I can

A multi-threaded HTTP/1.1 server built using raw sockets to understand concurrency, request lifecycles, and low-level networking behavior.

Highlights

• Persistent connections with concurrent request handling
• Rate limiting, path traversal protection, and CORS safeguards
• Prometheus metrics + structured logging for observability

Built to explore real-world performance trade-offs and backend fundamentals beyond frameworks.

A lightweight TypeScript-based migration system focused on reliability and safe schema evolution.

Highlights

• Transactional safety with automatic rollback
• Dependency resolution via topological sorting
• Migration locking & checksum verification
• Multi-database support

Designed to understand infrastructure tooling and failure scenarios in database workflows.

A multi-tenant platform designed to reduce certificate fraud and simplify placement workflows.

Highlights

• AI OCR with high-accuracy extraction
• Cryptographic signatures using Ed25519
• Row-level security for strict tenant isolation
• 90+ production-grade REST APIs with real-time features

Focused heavily on data integrity, security, and scalable backend architecture.

An intelligent system that improves information retrieval across multiple sources.

Highlights

• Semantic search using vector embeddings
• Automated knowledge graph generation
• Context-aware recommendation engine

Designed with performance optimization and structured knowledge discovery in mind.

• Backend-first thinking with strong full-stack delivery
• Bias toward reliability, clarity, and long-term maintainability
• Strong database fundamentals and growing system design intuition
• Comfortable reading docs deeply and exploring unfamiliar systems
