As a founding engineer, I led UI across web and app — from the first in-house framework to the Shopify-native pivot. - Established the foundation for UI engineering — design, standards, and patterns — and stayed in the code, shipping alongside the team. - Architected and shipped the platform's first version solo — a schema-driven system of primitives that composed storefronts across web and a mobile app — validating the model and landing the first paying brands (The Label Life, Includ, Ohsogo). - Helped grow the platform to $1M ARR — lifting conversion 30–50% on nearly every storefront it onboarded. - Drove store onboarding as the platform grew into a self-serve builder — shipping flagship storefronts hands-on for brands like Frido, Bombae, and Vaaree, among a dozen-plus D2C names. - Extended the foundation to create mobile apps for each store — on Capacitor, reusing the web codebase — and authored the native integration plugins (Shopify Checkout Kit, Klaviyo) available on npm. - Set the technical hiring bar — from take-home to live rounds — and mentored 10–20 interns and juniors, several to promotion. #### Spectrum Spectrum was the pivot back into Shopify — Tectonic's growth platform for D2C brands, consolidating 30+ storefront apps into one system with experimentation, personalization, and playbooks. I led its UI and migrated existing stores onto it. - Built Spectrum's Studio — a visual builder with A/B testing and personalization baked in, letting merchants tailor the storefront to different customer cohorts. - Developed the Spectrum Shopify app — one install that wires the platform into a merchant's store, unlocking the theme and data everything else runs on. - Improved GTmetrix grades from E–F to A–B — replacing third-party app bloat with Shopify-native Spectrum sections, blocks, and snippets rendered server-side. - Introduced AI-assisted development across the team — Claude skills, commands, and hooks that encode and enforce Spectrum's theme and performance standards, so the team ships safely with AI. ### Technical Lead · Virgio Mar 22 – Jul 23 Virgio is a D2C fashion label. As a founding-team engineer, I led the UI engineering charter from day one for both app and web. - Owned the architecture, technical direction, and quality bar — leading a team of 3–5 and driving delivery end to end. - Built a universal frontend — one codebase across native and web, with ~80–90% of the code shared. - Built the page service and rendering engine — screens rendered on the fly from a backend schema, shipping content, layout, and flows live with no app release. - Launched in two months and crossed 100k+ installs, staying solid at scale — 99% crash-free rate with near-zero ANRs. - Ensured the app stayed fast and fluid even on low-end devices, media-heavy screens and all — through performance optimizations across rendering, caching, and data fetching. - Hired and grew the UI team — turning junior engineers into independent owners of end-to-end delivery. ### Technical Lead · Myntra Feb 19 – Mar 22 At Myntra, I joined the Vorta team as an SDE-2 and grew into a Technical Lead. I led the frontend for the Market Intelligence Platform (fka Vorta.ai) and re-engineered Spectrum — the internal React framework behind most of Myntra's in-house tools. - Led frontend hiring and mentored engineers on the team. - Drove engineering-wide talks on React, web development, and performance. - Raised the frontend performance bar across Myntra's internal apps through Spectrum CLI. #### Market Intelligence Platform - Architected and built the frontend from scratch — shipped in a month with a two-engineer team. - Built the server-driven UI — dashboards, charts, and competitor views all rendered from backend-supplied config, personalized per seller. - Kept dashboards responsive at scale — dozens of Highcharts widgets over large per-seller datasets. #### Spectrum - Re-engineered the CLI — every generated app shipped 70–80% smaller with performance baked in (lazy loading, resource hinting, etc.), and version upgrades went from manual to automated. - 30+ in-house tools ran on it — nearly every internal app at Myntra. ### Web Developer · Greytip Jan 17 – Jan 19 Greytip offers HR and payroll software through its greytHR suite. I revamped its Employee Self Service (ESS) portal — the employee-facing app for payslips, leave, and attendance — and built its Employee Onboarding module from scratch. - Conducted internal Angular and TypeScript training sessions. - Earned the Rising Star award. #### Employee Self Service (ESS) - Built a JSON-driven UI framework from scratch that became the portal's rendering backbone. - Built the portal's UI kit — reusable components, services, and pipes — on an SCSS styling foundation. - Introduced and implemented app-wide state management with NgRx/Redux. #### Employee Onboarding - Built a store-driven, multi-step wizard from scratch to collect new-hire data. - Enhanced a JSON-Schema forms framework to render onboarding's metadata-driven reactive forms. ### Front End Developer · Eventifier Oct 16 – Jan 17 At Eventifier, I worked on a social-media aggregation platform — a real-time “livewall” that pulled, curated, and embedded user-generated content from Twitter, Facebook, Instagram, and Google+. - Built the livewall UI, moderation controls, and embeddable widgets that surfaced real-time social content across sites. ### Software Engineer · In Time Tec Jul 14 – Oct 16 I contributed to building Cartos — a managed-print-solution (MPS) tool where fleet designers plot and visualize enterprise printer fleets. - Architected and developed the entire frontend from scratch. - Built the interactive HTML5 Canvas editor (Konva) on a MEAN-stack SPA — designers dropped printers onto floor plans to lay out and visualize enterprise fleets. - Root-caused performance bottlenecks and kept the canvas responsive with the massive fleets of enterprises like HP and Xerox. - Established the frontend's unit-testing foundation with Karma and Jasmine. - Ran internal talks on JavaScript and AngularJS to level up the team. ## Skills - **Languages:** JavaScript, TypeScript, JSX, HTML5, CSS, Liquid, MDX - **Frameworks & Libraries:** React, React Native, React Native Web, Expo, NativeBase, gluestack-ui, Remix, Astro, Gatsby, Qwik, Angular, NgRx, RxJS, Redux, Zustand, React Query, Radix UI, Tailwind CSS, Framer Motion, Capacitor (Ionic), PWA, Konva, Highcharts, Shopify — Themes, Apps, Hydrogen - **Backend & Infra:** Node.js, Bun, Express.js, Hono, GraphQL, MongoDB, Firebase, Cloudflare, Vercel, Docker, Fly.io - **Testing & Tools:** Jest, Mocha, Jasmine, Karma, Playwright, Puppeteer, Storybook, Vite, Webpack, npm, pnpm, Yarn, Git - **Leadership:** Hiring & interview design, Coaching & performance management, Delivery ownership ## Education - **B.Tech Information Technology** — Swami Keshvanand Institute of Technology (SKIT) 2010–2014 · Jaipur, India ## Links - Website: https://hiteshkumar.dev - Blog: https://smellycode.com - GitHub: https://github.com/hk-skit - LinkedIn: https://www.linkedin.com/in/smellycode/ - Stack Overflow: https://stackoverflow.com/users/2879146
