  • Enhanced platform scalability through distributed service orchestration, reducing single-server load by 60%.
  • Improved API response time by 80% through optimized MongoDB indexing and data normalization strategies.
  • Designed and built microservices for SMS and email communication, and template management using gRPC, RabbitMQ, and internal APIs for scalable, modular development.
  • Optimized workflow automation by 100x, scaling from 1,500 to ~150,000 SMS/email messages sent daily using event-driven messaging queues.
  • Mentored 2 junior developers, enabling them to independently deliver features while maintaining high code quality.
  • Optimized and scaled payment integrations handling $100k–$500k in daily transactions with 99.9% accuracy.

SDE Intern @Maxyfi

Aug 2022 - May 2023

Some of the things I've built.

Portfolio Website Screenshot

Blood Request Application

A web-based application that streamlines blood request management by allowing requesters to submit blood requirements through a secure form. Requests are reviewed and managed via an admin panel, where details can be edited and exported as shareable images for quick circulation. The system supports time-bound access links, ensuring data validity and preventing misuse.

Upcoming Projects

Some exciting ideas I'm currently working on.

Custom Chatbot

A custom-built chatbot platform that allows organizations to upload their internal data (CSV or other supported formats), which is then analyzed, processed, and stored to create a structured knowledge base. The chatbot responds to user queries by retrieving answers strictly from the uploaded organizational data, enabling accurate, context-aware, and domain-specific conversations. This solution helps organizations provide instant, reliable answers without exposing external or generic information.
