About
A team-oriented engineer turning complex systems into shipped products.
I specialize in bridging machine learning, mobile, and scalable backends. My recent work focuses on smart vending machine platforms — building React Native operator apps, payment integrations, and robust API endpoints.
I'm equally comfortable training a CNN, designing a REST API, or debugging a complex state flow at 2am. I care about craft, performance, and shipping things that actually work in the wild.

From server to screen — reliable systems that scale.
I build robust software solutions around smart vending machines: secure Django/FastAPI backend servers, real-time data pipelines, and the React Native apps that operators and users rely on every day.
React Native operator apps
Cross-platform apps (iOS + Android) for technicians and store owners with offline-first sync.
Backend API & Services
Python and Django REST/FastAPI microservices to handle secure transactions and machine states.
Real-time synchronization
Low-latency web services and synchronization pipelines to track inventory levels, errors, and sales events.
Contactless payments
Integrations with UPI, RFID and QR for tap-and-go cashless transactions.
Real-time dashboards
Operator dashboards visualising fleet health, revenue and predictive restock alerts.
Advanced tools
Integrated automated testing tools and telemetry tracking for instant troubleshooting.
