Sujal Sanga Full-Stack & Backend Engineer | Node, Typescript, React

Why should you work with me ?

I'm a full-stack and backend software engineer with hands-on experience building reliable, production-grade systems across Node.js, Python, Go, React, and PostgreSQL. My focus areas are backend architecture, REST API design, real-time systems, and distributed systems engineering.

Professional Experience

At Hakimo.ai, I work on backend systems for an AI-driven security platform, owning features end-to-end — from requirements through production deployment. I designed an automated, multi-tenant incident-reporting pipeline, built a webhook integration layer syncing real-time third-party data, and redesigned our notification system's retry logic, reducing failed delivery rates by 68%. I also work with AWS services (DynamoDB, S3) for scalable data storage.

Previously, at DentalPaas, I developed RESTful APIs in Node.js/Express and built real-time WebSocket-based messaging features, alongside hands-on experience with Docker and Kubernetes deployment.

Independent Technical Projects

To deepen my expertise in distributed systems, I've independently built: a real-time trading dashboard with sub-100ms live data streaming; a Kafka-based workflow automation platform supporting multi-step, event-driven task orchestration; a distributed rate limiter benchmarked at 50,000+ decisions/sec; and a from-scratch implementation of the Raft consensus algorithm, the protocol underlying production systems like etcd and CockroachDB.

Education

B.Tech, Indian Institute of Technology Madras (CGPA 8.15/10). Ranked AIR 2289 in JEE Advanced 2021, placing in the top 1% nationally among 150,000+ candidates.

Engagement Approach

I take full ownership of assignments — scoping requirements, proposing sound technical approaches, and delivering clean, well-documented, maintainable work. I communicate proactively and am comfortable operating independently in remote, cross-functional environments.
