Smallcase is a comprehensive financial system that specializes in stock market investments and the management of stock portfolios. Its demanding nature requires a robust, high-performance backend that operates with minimal downtime. As a seasoned engineer, I have repeatedly encountered unique challenges in this domain, and have successfully engineered innovative and scalable solutions to address them. My experience in designing and developing backend systems for Smallcase has equipped me with the skills and expertise needed to deliver top-notch performance and reliability, even in the face of complex and evolving market dynamics.I own and maintain multiple microservices, a few of them are- A real-time stock price tick service.- An observability library that hides all the complexities of opentelemetry and provides a clean and minimalistic API. With this library, any service can easily send logs, traces, and metrics to the telemetry backend, without having to deal with the intricacies of opentelemetry.- A service that talks to 10+ major stock brokers in India and provides a common parameterized API for other internal services.- and many more.I have mentored engineers on many projects, helping them to have a better approach to problems and come up with optimal and scalable solutions.

I developed a complete backend system for this Ed-Tech platform. This involved creating APIs for user authentication, user dashboard, a full Learning Management System (LMS), video conferencing, payments, referrals, and email/SMS notifications from scratch. The result was a robust and user-friendly platform that met all requirements.
