Aditya Srivastava

I’m a full-stack software engineer with hands-on experience building production-grade systems across fintech and marketplaces. As a Founding Software Engineer at BuildBazaarX, I led end-to-end development of a scalable multi-role marketplace—owning architecture, frontend, backend, database, and deployment—while building core systems like authentication, payments, dashboards, and workflows across 10+ modules.

I also manage delivery end-to-end: I led a team of 3–5 junior developers through task execution, code reviews, and timelines, while optimizing APIs, application performance, and state management to reduce redundant operations by 40%+. Earlier, as a Software Developer Intern at OptionX (Ratel Fintech Pvt. Ltd.), I built a high-performance React instrument search (infinite scrolling, keyboard shortcuts, contextual trading actions) and reduced search-to-action latency by 40% for 1K+ daily users.

I’m drawn to engineering that connects product outcomes with strong technical execution. I built monitoring infrastructure with n8n workflows and a Python FastAPI service to verify price feed integrity at market open and trigger real-time Slack alerts, and in my projects I’ve delivered real-time, AI-enhanced trading experiences using Next.js/React, Fast APIs, MongoDB/PostgreSQL, and event-driven alerting (Inngest) for low-latency performance and reliability.
