I build products
for web and mobile

The marketing and product site for an AI practice companion app for piano tutors, with a full in-browser product walkthrough that lets prospects trial the real app: lesson start, live listening, and a results dashboard with insights and games. A playable piano is synthesized in real time with the Web Audio API, and scroll-driven GSAP ScrollTrigger timelines stay pinned correctly across device rotation via a ResizeObserver with scoped cleanup. Tutor scheduling runs through Google Calendar OAuth, with download conversions tracked via Meta and TikTok Pixel.

A tutor onboarding and scheduling platform used to onboard 2,000+ tutors across the UK and US, with dual path Google OAuth and email signup, Google Calendar sync, a per-day availability picker, and device-aware QR code onboarding.

A full e-commerce storefront for music learners and enthusiasts, with product browsing, cart management, and a complete, secure checkout flow built for real transactions.

A cross-platform tutor app used by 2,000+ music tutors, embedding a web dashboard in a native WebView with a two-way JavaScript bridge. Includes Stripe Connect onboarding with live payout verification, a resumable chunked audio upload queue, and Google and Apple Sign-In.

A cross-platform learning app for 14,000+ students across iOS and Android to book lessons, purchase instruments, and manage subscriptions, supporting 96,000+ lessons delivered and 800+ paid subscribers. End-to-end checkout lets students pick lesson type, duration, and bundle size, then pay for lessons and instruments together in one purchase, while two subscription tiers unlock practice games and a separate progress-analytics experience. Account self-service covers password reset via emailed one-time code, profile editing, balance breakdown, and full payment history.

Bilingual farm management app letting Bangladeshi farmers log milk sales, feed costs, and buyer dues from the field, offline. Calculates profit per animal and feedlot cycle, giving smallholders numbers to price stock and chase overdue payments.

IELTS preparation app spanning all four exam modules with timed mock tests, spaced repetition vocabulary, and progress analytics. Works fully offline, estimates band scores from real practice, and shows learners which module is holding their score back. Engineered a fully local React Native architecture with persistent storage for highly scalable, zero latency educational content while eliminating backend infrastructure costs.

A Bengali-localised EdTech platform built for a coaching academy in Bangladesh, covering academic classes, admission prep, skills courses, and English language training. Built on a reusable widget-based UI system with Tailwind CSS and shadcn/ui, with Framer Motion animations for counters, transitions, and scroll reveals, over a type-safe TypeScript domain layer modelling courses, quizzes, payments, and dashboards. The full course catalogue, navigation, and platform messaging are localised into Bengali while preserving standard exam terms like SSC and HSC, so the product is genuinely usable for its target students rather than a translated afterthought.

A responsive agricultural e-commerce storefront for the Bangladesh market, covering product catalogue, cart, wishlist, and checkout. Category pages are server-rendered for search visibility, with client interactivity isolated to cart and checkout, and a persistent cart and wishlist built on one reusable state pattern so shopping progress survives reloads with no backend call. The three-step checkout covers shipping, payment, and confirmation, with schema-based validation catching invalid input before review.

A real-time chat client for direct and group conversations, built on a provided REST and Socket.IO backend. Socket events are written straight into the TanStack Query cache instead of refetching, cursor-paginated history de-duplicates as it pages in on scroll, and a feature-folder architecture keeps server state and client state strictly apart behind an ESLint-enforced dependency boundary.

A pixel-perfect implementation of a two-breakpoint Figma landing page, served its content by a small standalone Express API. Every section renders explicit loading, error, and success states through a strict one-direction data flow, and the app is covered by two independent test suites, one for the API and data contract and one for component behavior.

A straightforward hotel reservation site where users can browse rooms, check availability, and make bookings, built with pure HTML, CSS & JavaScript.
