- Developed an assisted bill payment system for merchants.
- Performed load testing and benchmarking using Locust and Bombardier.

• Developed a proxy using Go, that can replace the previous one (Java based) to reduce thread based failures replaced with Go's coroutines (Go routine). But it didn't go live as lack of Go devs.

• Developed a secured dynamic QR generation system for all kinds of transactions and identifications. This provides personal QRs for millions of users and also thousands of businesses.
- Designed the authentication system with JWT and RSA encryption.
- Validated the QR fetching system with checksum validation.

• Contributed in building the backend of a merchant ecosystem for 100K+ merchants.
- Coded a distributed job processing to generate transactional reports.
- Implemented microservices concept with modularity and data store decoupling.
- Researched and developed the backend system with the reactive concept.
- Innovated a log trace system for reactive programming.
- Systemized a stateful token system for authentication and authorization.
- Devised a notification system with the reactive concept.

• Inspired team to use latest stacks like Vert.x, WebFlux, learn other languages like Go, Python, and architectural patterns like message driven systems.

• Participated in code reviewing and peer programming and tech discussions.
