Hevenland is a delivery cloud kitchen in Cumilla, Bangladesh. I built the whole platform for them through Rorocode: the website customers order from, the counter POS their branches bill with, and the admin software the owner runs the business from.

Role: Scope, design system, frontend, database, security and launch — as Rorocode. Stack: Next.js, TypeScript, Tailwind CSS, shadcn/ui, Supabase, Sentry, Upstash, Vercel.

One Ayah — Own product

An Islamic app I'm building. Every day it gives you one ayah — just one — with its meaning and tafsir, so there is always something to carry through the day. More features grow around that single daily verse.

Role: Design and development — currently in testing before the Play Store launch. Stack: Android, Mobile.

HR Management Hub — Employer

At ESAP I work on an ERP suite, mostly connecting agentic AI to it. The HR hub runs employees, attendance, leave and payroll under Saudi labour law and GOSI rules, with agents that answer HR questions and do the busywork.

Role: Founding team, software developer — frontend and AI workflow integration. Stack: React, Next.js, TypeScript, Node.js, Express.js, MongoDB, Gemini, n8n.

Finance Agent — Employer

The other half of my ESAP work: AI agents connected to the ERP, the FMS and the financial app, so people can ask questions in plain language and get answers that show their work.

Role: Founding team, software developer — interface and agent integration. Stack: Next.js, TypeScript, Node.js, Gemini, OpenAI, Tool calling.

Zeigen Health — Employer

Zeigen is a digital therapeutics platform with evidence-based tools and integrated cognitive behavioural therapy. I worked on the frontend architecture across the web platform and the React Native apps.

Role: Frontend developer — web and mobile. Stack: React Native, Next.js, TypeScript, Redux / RTK Query, shadcn/ui, AWS.

Rorocode — Website

Rorocode is the agency I run alongside my job — AI automation, web and app development for early-stage clients. The site is a motion-led portfolio: magnetic cursor, word-reveal typography, parallax case studies.

Role: Design and development. Stack: Next.js, TypeScript, Tailwind CSS, Framer Motion.

Veyra Bank — Website

A motion study: a digital-bank landing page where the card tilts with the cursor, the deck fans out as you scroll and the security copy lights up word by word — with no animation library.

Role: Design and development. Stack: Next.js, React 19, TypeScript, CSS.
