Developing scalable software solutions with a focus on performance, user experience, and reliability
Engineering with
Form & Function.
I build scalable software solutions designed for performance, reliability, and efficiency. My work focuses on developing high performance systems that can handle complex workflows, process large volumes of data, and execute with precision.
I enjoy working across the stack building robust backend systems, intuitive user interfaces, and seamless integrations that deliver reliable and efficient experiences. My approach to engineering is shaped by working in demanding environments, where system behavior, performance, and stability matter as much as clean code. I’m particularly interested in building systems that go beyond static applications software that is responsive, efficient, and capable of handling real-world complexity at scale.

Full-stack Software Engineer Apprenticeship
Full-time100xDevs · Delhi NCR, India (Remote)
- Led end-to-end design and development of a high-performance algorithmic trading platform built on a low-latency C++ core with a modern React-based terminal.
- Engineered a distributed, microservices-style architecture with WebSocket-based real-time data streaming, a multi-threaded datafeed system, and a high-speed execution engine with integrated risk management.
- Implemented hybrid execution modes for live trading and historical backtesting, along with an embedded browser-based IDE for strategy development, real-time visualization, and seamless strategy deployment.
- Architected a simulated crypto CFD trading engine (BTC, ETH, SOL) as an event-driven microservice system wired through Redis Streams and QuestDB snapshots, so trades replay deterministically and positions survive restarts.
- Built a real-time portfolio tracker using TypeScript with Redis caching, precomputed PnL metrics, and load-balanced WebSocket pipelines for low-latency updates.
Full-stack Software Engineer Intern
InternshipPeples Brands Lab · Delhi NCR, India (Remote)
- Drove an ecommerce SaaS from idea to MVP in ~3 months by designing a scalable backend + frontend architecture, implementing feed/cart/order/payment flows.
- Built a reusable Next.js + Tailwind component library that replaced spreadsheet workflows and cut new dashboard view build time from days to hours.
- Partnered with founders from zero to launch to ship the first production website, implementing a modular component system (hero, feature rows, FAQ, CTA) and wiring in analytics and env-based config.
- Enabled the team to roll out, A/B test, and rollback new pages safely within days instead of weeks.
