Portfolio
Selected work
Real projects, real results. Eight case studies across digital marketing, AI, data analysis, and study abroad.
JJAT Education
Founded and built JJAT Education — an international student consultancy based in Dhaka, Bangladesh. Designed the full digital presence, implemented an AI-powered student intake chatbot handling initial queries and qualification screening, and built automated workflows covering 23 study destinations. The platform now supports 500+ student applications across the UK, Australia, EU, Canada, and beyond.
Study Abroad Mentorship
Personal mentorship for students applying to UK, Australian, EU, and Canadian universities — outside of JJAT Education. Worked with 30+ individual students providing tailored personal statement coaching, application strategy, scholarship research, and visa guidance. Students secured offers from University of Aberdeen, Edinburgh Napier, Glasgow Caledonian, and more.
RAG Customer Support Chatbot
A fully functional GPT-powered customer support chatbot using Retrieval-Augmented Generation (RAG). User queries are matched against a product knowledge base (returns policy, shipping, payments) — the top-k relevant chunks are injected into the system prompt before the LLM responds. Built with Next.js 15 App Router, AI SDK v6, and streaming responses. Falls back to scripted demo responses when no OpenAI key is set, so the live demo always works.
SaaS Marketing Website Template
A full SaaS marketing website built with Next.js 15 and Tailwind CSS v4. Includes hero, features grid, three-tier pricing table, testimonials, and CTA sections — all statically rendered for maximum performance. Demonstrates responsive dark-theme design, smooth scroll navigation, and accessible interactive elements. Deployed to Vercel with zero config.
Multi-Source Analytics Dashboard
A unified analytics dashboard pulling from GA4, Shopify, and Postgres into one dark-themed view. Shows 6 KPI cards, area/bar/line/pie charts, and a top-pages table — all seeded with realistic 2024 mock data. Built with Next.js 15 server components and Recharts. Demonstrates how to normalise data schemas across sources and render large datasets without blocking the UI.
Service Booking Mobile App
An interactive mobile UI demo showing the full booking flow for a React Native home services app — browse services, pick a date and time, enter card details, and get a booking confirmation. Built as a pixel-perfect phone frame simulation running in the browser. The actual React Native app uses Expo Router, Zustand, Stripe Payment Sheet, and React Native Reanimated for 60fps animations.
AWS Serverless Infrastructure
An interactive architecture diagram of a production AWS CDK v2 stack — click any component to see the TypeScript CDK code that provisions it and why it was designed that way. Stack covers: API Gateway HTTP API → Lambda (Provisioned Concurrency) → SQS + Worker Lambda → RDS Proxy → Aurora Serverless v2, all inside a private VPC. Secrets via SSM Parameter Store, static assets on S3 + CloudFront, CI/CD via GitHub Actions with cdk diff on PRs.
Meta Ads Performance Audit Tool
A paid social audit tool that analyses 5 mock Meta Ads campaigns and flags issues: poor ROAS, ad fatigue (high frequency), audience overlap, and underperforming creatives. Each issue comes with a specific fix recommendation prioritised by impact. The live demo uses seeded mock data — the architecture shows how it would connect to the real Meta Marketing API via OAuth 2.0 with server-side token proxying.
