Quantech Associates is a service-based company. As a frontend engineer here, I am currently working on a client project — a large-scale home services platform operating a subscription model for HVAC, water heating, and plumbing equipment rentals. With 1.2M+ active customers, the platform's customer portal handles service bookings, technician scheduling, and rental agreement transfers at high volume.

Contributions

• Redesigned the critical Moves flow end-to-end

  Led the redesign of the customer Moves flow — a high-stakes form used by renters and homeowners to transfer or close rental agreements. Rebuilt it as a multi-step React form with per-step progressive validation and Redux Persist–backed state management, so users never lose progress mid-flow.

• Revamped the service booking experience

  Overhauled the booking flow used by 1.2M+ active customers to schedule technicians for HVAC, plumbing, and water heating services. Focused on reducing friction at each step — cleaner inputs, inline validation, and a persistent progress indicator that cut drop-off significantly.

• Built a reusable component-driven UI library

  Engineered a shared UI library using shadcn/ui, TailwindCSS, and Storybook to standardise components across the platform. The library enforced design consistency, enabled cross-browser compatibility, and gave the team a documented component catalogue that cut UI development time by 30%.

• Frontend performance optimisation across the portal

  Audited and improved page load performance through lazy loading, route-level code splitting, and API integration refinements. The improvements had a measurable impact on booking conversion rates, particularly on mobile and lower-bandwidth connections.

Logic Square Technologies is a service-based company. During my time here, I was part of the team working on a client project — Grouped, a social music discovery platform for indie artists and listeners. With 20K+ active users, the challenge was architecting features that could scale reliably while keeping the feed performant and the codebase maintainable.

Contributions

• Led frontend development on Grouped

  Led frontend development on Grouped — a client-facing social music platform for indie artists. Built core features using Next.js, TypeScript, and Redux Toolkit, establishing patterns for scalable state management and component reuse across the app.

• Infinite scrolling and dynamic pagination

  Implemented intersection-observer-powered infinite scrolling with dynamic pagination across the music feed. The experience felt native and instant, increasing average session length by 25% and meaningfully improving user retention.

• Custom reusable video player in React

  Built a fully custom video player component from scratch, replacing a bloated third-party library. The reusable component reduced technical debt, eliminated an unnecessary dependency, and cut integration time by 40% across multiple projects that adopted it.

• Reusable form validation hook

  Developed a standardised form validation hook that was reused across 5+ projects within the company. It centralised validation logic, enforced consistent error handling patterns, and reduced repetitive boilerplate by 20% — making new form implementations significantly faster.

Makos Infotech is a Chennai-based IT solutions company offering web development, staff augmentation, HR services, and digital consulting. As a UI developer intern, I worked on Jobaskit — their in-house recruitment product built to streamline the hiring process using collaborative intelligence.

Contributions

• Built Jobaskit — a recruitment platform from scratch

  Developed Jobaskit, a collaborative intelligence-based recruitment platform, entirely from the ground up using HTML, CSS, JavaScript, and Bootstrap. Took it from zero to a fully functional product, owning the entire frontend implementation end-to-end.

• Admin dashboard for user data management

  Built a clean, intuitive admin dashboard using JavaScript and Bootstrap that gave the operations team full visibility and control over user data. Focused on making complex data management tasks feel simple and fast through clear information hierarchy and responsive layout.

• Performance optimisation via lazy loading

  Identified performance bottlenecks in the initial page load and implemented lazy loading across assets and components. The result was a 200ms improvement in load time — a meaningful gain that made the platform feel noticeably snappier on first visit.

Ziroh Labs (now Kompact AI) is a deep-tech startup building privacy-preserving compute infrastructure — enabling AI and data processing without exposing raw data. As a project intern during college, I worked on a developer-facing search interface where input responsiveness and low latency were hard requirements, not nice-to-haves.

Contributions

• Autocomplete engine with fuzzy matching

  Built a search-as-you-type autocomplete component with fuzzy matching and keyboard navigation. Implemented using a trie data structure on the client for instant suggestions on cached results.

• Spell-check with debounced correction API

  Integrated a spell-check layer with 300ms input debouncing. This batched requests and eliminated redundant API calls, significantly reducing server load and latency.

• Input performance profiling

  Profiled keypress-to-render latency using the Chrome Performance tab. Identified and eliminated unnecessary re-renders in the suggestion list, cutting response time by 30%.
