Core Expertise

Transitioning monoliths to scalable microservices. Event-driven architectures, pub/sub, message queuing, and highly available deployments.

ARCHITECTURE

Identifying bottlenecks at scale. Heavy query optimization, vector search indexing, aggressive caching strategies (Redis), minimizing p99 latency.

PERFORMANCE

Engineering enterprise RAG systems, vector embeddings, high-dimensional similarity search (ANN/HNSW), vector databases (ChromaDB, Pinecone), local model orchestration with Ollama, and OpenAI/Gemini integrations.

GENAI & RAG

Building ultra-low latency peer-to-peer communication, WebRTC signaling servers, and real-time bidirectional data streams.

Experience

Software Developer

Sept 2022 - Present

Progression: Intern → Backend Dev → SDE

▹ Architected and developed scalable, fault-tolerant backend systems powering high-volume, real-time platforms.
▹ Took full ownership of system design, including database modeling, API development, caching, queuing, and load balancing, ensuring high performance, reliability, and maintainability.
▹ Optimized workflows and infrastructure, reducing operational overhead by over 60% and cutting third-party API costs, enabling efficient and scalable product delivery across the platform.

I used to think checking username availability was just:
SELECT * FROM users WHERE username = 'abc'
Then I started reading how systems handle this at billion-user scale 😭
