Full-stack developer · Agency founder · Visual storyteller
I am Harmanpreet Singh — founder of HPX Studio. I build fast, deliberate digital products end-to-end: strategy, design, engineering and the monitoring that keeps them healthy long after launch.
I build products that feel fast, look intentional, and tell stories users remember.
The stack behind every build — from first commit to production monitoring.
Mobile ApplicationA comprehensive mobile health and nutrition tracking application with diet logging, health monitoring, and analytics built for offline-first mobile experiences.
Mobile ApplicationA modern, feature-rich Android music player with YouTube integration, background playback, playlist management, and lock screen controls.
Game DevelopmentA collection of real-time multiplayer games including Tic-Tac-Toe, Bingo, and Dots and Boxes, playable across network with live gameplay synchronization. Self-hosted on a Raspberry Pi.
Web ApplicationSecure, encrypted messaging platform with friend request system, real-time status, image sharing, and end-to-end encryption for private communications. Self-hosted on a Raspberry Pi.
ERP SystemA custom ERP system for a major healthcare franchise provider, featuring sales tracking, CRM and dozens of modules that streamline daily operations.
Every build starts with the "why". I map business goals to a technical roadmap before a single pixel moves.
Wireframes to polished prototypes — interfaces where every pixel has a purpose, backed by real color theory.
Clean architecture, type-safe code, production-hardened infrastructure. Engineered for real-world pressure.
Shipping is the midpoint. Health checks, speed audits and analytics keep every product accountable.
For personal brands & early startups
For businesses that need an engine, not a brochure
For products with real users and real stakes
The ERP HPX built runs our daily operations — sales, CRM, Tally integration. It has been reliable through every peak season since launch.
Harmanpreet thinks like a product owner, not a contractor. He challenged half our spec and the product shipped better and earlier because of it.
We hand HPX the builds we cannot afford to get wrong. Fast, communicative, and the Lighthouse scores speak for themselves.
Treating the network as an enhancement — not a requirement — changed how I architect every mobile app. Here is the exact pattern I use.
