HI, I'M SANDEEP
Product &
UX Designer
“I help founders who cares about their user to design thoughtful and impactful apps, not just another slop”
Selected Work
A selection of products, applications, and digital experiences I've built with focus on craft, usability, and scale.
More than just code.
I care about the details behind great software — from architecture and performance to interaction and user experience.
I am a full-stack engineer based in Kathmandu with a passion for building robust web applications and intuitive interfaces. Over the last 5+ years, I've collaborated with startups and agencies across the globe to turn ambitious technical challenges into production-ready software.
My philosophy centers on simplicity, maintainability, and end-user empathy. Good software isn't just about writing clever algorithms—it's about creating resilient systems that load in milliseconds, feel tangible to the touch, and solve practical business problems.
Clean boundaries, normalized schemas, and zero redundant bloat.
Edge caching, aggressive bundle optimization, and high Lighthouse scores.
Natural spring physics, haptic feedback, and accessible keyboard navigation.
Strict type safety, automated end-to-end testing, and clean git history.
What I do
From idea to production, I help turn complex problems into simple, high-performing digital experiences.
Full-Stack Development
End-to-end web applications with robust foundations.
From database schema design to clean user interfaces, I engineer production-ready web applications that scale with your business and deliver exceptional performance.
Frontend Development
Fluid, high-performance interfaces built for all screens.
Crafting performant, accessible, and responsive user interfaces using modern React ecosystem tools. Every interaction is fast, predictable, and delightful.
UI Engineering
Design systems and micro-interactions with polish.
Bridging the gap between design and engineering. I turn static Figma frames into living, breathing design systems with micro-animations and accessibility baked in.
Product Development
Translating concepts into shippable digital products.
Partnering with founders and engineering leaders to iterate rapidly from MVP concept to market launch, focusing on user feedback and clean code maintainability.
Tools I work with
Curated technologies and libraries I leverage daily to engineer fast, resilient, and maintainable software.

How I work
A structured, collaborative approach to delivering high-impact digital products on time with zero surprises.
Understand
Deeply research the domain, user pain points, business goals, and technical constraints before writing a single line of code.
Plan
Define architecture, database schema, API contracts, interactive component boundaries, and milestone execution strategies.
Build
Develop the product with clean, type-safe, modular, and maintainable code. Continuous integration and frequent demo reviews.
Refine
Optimize performance, polish animations, ensure WCAG accessibility, deploy to edge infrastructure, and monitor user feedback.
Kind words from people I've worked with
Notes and recommendations from founders, design partners, and engineering leaders.
“Sandeep has an exceptional ability to turn complex design requirements into seamless, lightning-fast code. His attention to detail, typography, and interaction nuances sets him apart from most full-stack developers.”
“Working with Sandeep was effortless. He delivered our e-commerce platform ahead of schedule, with zero regressions and Lighthouse scores in the high 90s. His code is clean, modular, and easy for any team to maintain.”
“A developer who truly cares about craft. Sandeep doesn't just write code; he thinks through the user experience, edge cases, and accessibility from day one. I'd hire him again in a heartbeat.”
Things I've been exploring
Side projects, creative experiments, open-source utilities, and UI interaction labs.
Minimalist Ray Tracer in WebGL
Real-time browser shader exploring diffuse reflections, spherical ray-casting, and ambient occlusion.
