ABOUT

↓ SCROLL01

I design high-throughput API architectures, concurrent services, and scalable cloud-native infrastructure.

Based inPunjab, India
Experience2+ Years
SpecialityBackend + System Design

Based in Punjab, I am actively specializing in Golang (Go) development and Advanced System Design. I apply clean architecture principles, robust data normalization patterns, and secure design patterns to engineer production-ready software solutions.

    A production-grade, offline-first Flutter e-commerce platform built using the Repository Pattern and reactive BLoC state management. Engineered with a secure Supabase (PostgreSQL) database implementing Row-Level Security (RLS) and ACID-compliant order processing. Configured with automated CI/CD pipelines for secure iOS code-signing and App Store Connect delivery, as well as Google Play Store distribution.

The web is loud, and most brands just blend into it. I work across design, development, and branding all at once, building digital experiences that feel as sharp as they look. Nothing gets handed off between teams or lost in translation, because I build every layer myself. That's how the identity we create together actually holds up once it's live. If your brand deserves to be seen, let's make sure people can't look away.

I'm not here to just write code; I'm here to build systems that scale. From designing high-throughput API architectures to implementing robust microservices, I ensure that every component is engineered for reliability, security, and performance.

My focus is on the unseen layers that power digital products—caching layers, message brokers, and secure databases. I take pride in creating clean, maintainable, and resilient backend infrastructure that forms the backbone of any successful application.
