Roles I work in
Design engineer
A design engineer designs a product's interface and builds it in production code, so nothing is lost between the mock-up and what ships.
Arun has worked this way since 2023: the main UX design engineer on HP's Innovation for India team, then founding design engineer at Spera.bot, where he leads design and the Next.js frontend end to end.
Design technologist
A design technologist sits between design and engineering: prototypes that run, design systems in code, and the tooling that lets a team ship design faster.
He built Mudra, HP's internal design system in Figma and Next.js used by 500+ employees, and at Spera a feedback loop that turns an in-app UI report into a prompt wired to the team's specs.
Creative developer
A creative developer builds expressive, interactive web experiences, such as 3D, motion, sound and shaders, that still load fast.
kiruk.in opens on a realistic 3D eye written in Three.js TSL for WebGPU and drawn from a Web Worker. He also built prahatheesvar.in, a scroll-to-play instrument site in Three.js, Howler.js and GSAP.
Product designer who codes
A product designer who codes does the research, flows and UI, then builds the real thing instead of handing off a file.
On Square Bridge he led three designers across 150+ screens tested with 200+ people; its Portfolio Builder raised student engagement 45% and shipped at 98% design-to-code accuracy.
Freelance design consultant for creative work
A freelance design consultant joins for a project or a fixed time: product and brand direction, creative websites, design reviews or a design system, handed over in a state the team can run.
He has freelanced since 2018, for studios, resorts and musicians, wrote his first design systems for clients, and has taught UX to 100+ students.
Ways to work together
Freelance projects
A fixed scope with a clear end: a creative or marketing website, a product's UX and UI, a Three.js experience, a design system or a design audit. Remote, for businesses in India and abroad.
Contract and part-time
Embedded in your team for a set number of weeks, or a few days a week, as design engineer or design technologist, working in your Figma, repo and rituals.
Full-time roles
Open to conversations about full-time design engineer, design technologist, creative developer and senior product designer roles, remote or in Bengaluru.
What I can do for you
- Product and UX design: research, flows, wireframes and UI
- Design systems: components and design tokens, in Figma and in code
- Front-end engineering: React, Next.js and TypeScript, production-ready
- Creative and interactive websites: Three.js, WebGPU, WebGL shaders, motion and sound
- AI product UX: chat, agent and MCP interfaces people trust
- Working prototypes: for user testing and for pitching
- Brand identity: logo, voice and visual direction for products
- Design consulting: design reviews, UX audits and design-engineering process
Proof
- HP Print AI, the first printer experience built around AI (HP Inc, Innovation for India).
- Mudra, HP's internal design system in Figma and Next.js, used by 500+ employees.
- Square Bridge Portfolio Builder: student engagement up 45%, recruiter discovery time down 40%.
- Spera.bot: brand, design system and production frontend since February 2026, 330+ commits.
- 15+ hackathon solutions at HP; UX taught to 100+ students.
- kiruk.in itself: a 3D eye in Three.js TSL on WebGPU, seen through ten eras of screens.
Case studies are on the work page; the full background is on my profile.
How I work
We sit together, ideate and start from a sketch. I take it to a working version quickly, test it with real people, then encode what we learned as a spec, a token or a component so the next pass doesn't start from zero. You get the design files and the code, documented so your team can run them after I leave.
