Featured Projects
A showcase of my work across various industries and technologies
Ali Pro
Multi-Tool AI SaaS Platform
A subscription AI platform offering 17 specialised tools, including document summarisation, legal document analysis, medical report generation, code assistance, image generation, and speech to text. Built a provider-agnostic AI layer that routes each tool to the right model across OpenAI, Anthropic Claude, and Google Gemini behind a single interface, so providers can be swapped without touching tool code. Implemented a credit-based wallet with Stripe subscriptions, top-ups, plan changes, and idempotent webhook processing, plus a cost-guard service enforcing per-provider monthly spend caps that blocks execution before any credit is charged.
Wair
Peer-to-Peer Fashion Marketplace (UAE)
A UAE marketplace connecting individual buyers and sellers, with Stripe Connect Express handling seller onboarding, commission splits, escrow, and automatic fund release 48 hours after delivery. Implemented real-time buyer-to-seller messaging over Laravel Reverb WebSockets with web push notifications, a multi-stage dispute and partial-refund workflow, and a Filament admin panel for operations. Delivered in English and Arabic with full RTL support, serving listing images through Cloudflare R2 and CDN.
KmerBus
Intercity Transport & Parcel Logistics PWA (Cameroon)
A multi-tenant platform for Cameroonian bus operators covering seat-map ticket booking, QR-coded tickets, and parcel delivery. Integrated MTN Mobile Money and Orange Money, the dominant payment rails in that market, alongside an offline cash-desk mode so station agents can sell tickets without customer internet access. Implemented a five-stage photo-proof parcel delivery chain, a seven-role permission system, and a financial ledger with refund handling, delivered as an installable PWA in French and English.
YouWannaTrade
Buy, Sell, Trade & Auction Marketplace
The one-stop marketplace to buy, sell, trade and auction in one place. The listing schema runs on PostgreSQL JSONB with a GIN index and generated columns, across fourteen categories with their own attribute families. Includes matching between listings and trade preferences, offers, buyer and seller messaging, dealer profiles, and a Filament admin panel.
Termometro Social
Real-Time Public Opinion Platform (Spain)
Reads the Spanish press continuously, groups every article covering the same event, writes one neutral for / against question per topic, and shows how the country answers in real time. One Laravel application runs as the HTTP API, a queue worker for the news pipeline, and a websocket server for live results, with a server-rendered Next.js public site.
BikriBondhu AI
AI Sales & Support Agent SaaS (Bangladesh)
A multi-tenant conversational commerce SaaS for Bangladeshi small businesses and F-commerce sellers, where an AI agent handles sales and support across chat channels. Built the Super Admin panel, the Merchant panel, the Live Inbox, and a separate public marketing site.
One Night Guest
Event Venue & Services Classifieds (Mexico)
A Spanish-first advertising platform for event venues and services in Mexico, with map search, favourites, reviews, and inquiries. Runs on advertiser subscriptions, part of each fee funding a Google Ads campaign for their ads, plus budget top-ups, identity verification, and a sales pipeline for building prospect ads for leads.
OushodhKhata
Pharmacy Management SaaS (Bangladesh)
A multi-tenant SaaS for independent pharmacies covering sales, purchases, batch-wise stock, expiry tracking, expenses, suppliers, shop-to-shop product exchange, and stock count discrepancies, with each pharmacy's data isolated through PostgreSQL row-level security. Available in Bangla and English, with thermal receipt printing.
OposChat
AI Study Assistant for Spanish Public-Sector Exams
A retrieval-augmented AI tutor that answers candidate questions strictly from an uploaded legal and course document corpus. Built the full RAG pipeline: ingestion with semantic and legal-structure-aware chunking, embedding storage in ChromaDB through a Python FastAPI bridge, and hybrid retrieval combining vector similarity with BM25 reranking and query rewriting. Designed a four-stage relevance gate that refuses off-topic questions without ever calling the language model, cutting wasted API spend and preventing hallucinated answers. Added SSE token streaming, AI-generated quizzes, rubric-based automated grading, and an adaptive engine tracking weak subtopics per student.
My Math Olympiads
Online Mathematics Examination Platform
An examination platform for mathematics competitions with a drag-and-drop question builder, LaTeX equation authoring and rendering via MathLive and MathJax, timed exams, automated grading, and generated PDF certificates. Implemented role-based access for students, teachers, and administrators, bulk question import and export through Excel, Stripe payments, and Swagger API documentation.
Shopify Theme & Store Development
Custom Storefronts & Store Operations
Built and customised Shopify storefronts with theme development in Liquid, writing custom sections and snippets for age verification, cart drawers with gift wrapping, countdown and flash-sale blocks, image comparison, product sliders, and a store locator. Also handled the operational side: bulk product import, inventory management, reusable upload templates for merchants to run their own catalogue, and multichannel selling across Shopify and eBay with matching shipping and payment policies.
Qatarat App
Water Delivery Platform for Mosques
Developed and maintained APIs for the client and driver mobile applications as well as the admin panel. Integrated advanced booking, real-time notifications, and live tracking, working closely with mobile developers to ensure seamless API communication.
These are selected projects. More of my work lives in client and company repositories, with 138 repositories on my GitHub.
