Senior Full Stack Engineer based in London. Five years building EdTech products end-to-end — backend systems, AI integrations, and the UI users actually touch.

I'm Sagar — a Senior Full Stack Engineer based in London. Five years at Maqsad, an EdTech platform serving 4M+ students , where I was promoted from Graduate to Senior in three years. I build products end-to-end — DynamoDB schemas, NestJS backends, payment integrations, AI features, and the UI users actually touch. Currently pursuing my MSc in Software Engineering at the University of Hertfordshire.
Build
Full stack engineering across the stack — Node.js / NestJS backends, DynamoDB and MySQL schemas, payment integrations, auth, and the React / Next.js frontend on top.
Integrate
Production AI work — OpenAI, Whisper, Twilio. Built multilingual chatbots that actually help users. Plus 40% SEO-driven traffic growth at Maqsad.
Own
Promoted Graduate → Senior in three years. End-to-end feature ownership — like Chaabi, the entitlement system I built at Maqsad. Always shipping.

What I reach for when I'm building something.
Frontend
Interfaces users actually want to use. Web and iOS.
Backend
APIs, real-time messaging, and the cron jobs that keep things running.
Data & Cloud
Schemas, caching, and the infra it all sits on.
AI & Integrations
Models, voice, messaging, and payments wired into production.
Things I've built that people actually use.
EdTech Platform · 2021 — 2026
Maqsad is an EdTech platform serving 4M+ students across Pakistan, with 16M+ doubts processed and 500+ university admissions facilitated. I joined as a Graduate Engineer pre-launch and was promoted to Senior in three years, owning features across the stack.
What I built
Chaabi— internal entitlement system controlling product access across user cohorts. Backend owner.
Payments— integrated Stripe, JazzCash, and EasyPaisa for course purchases and subscription flows.
SEO growth— drove 40% increase in organic traffic through SEO strategy and on-page optimisation.
AI chatbot— shipped a ChatGPT-powered support assistant that simplified multi-step student queries.
Support automation— NestJS cron jobs pulling real-time updates from the support email inbox into Slack.

MSc Capstone · University of Hertfordshire, 2026
A multilingual conversational AI providing UK legal guidance over WhatsApp. Auto-detects the user's language and responds in kind, supporting both text and voice conversations.
What makes it interesting
WhatsApp Business API integration via Twilio — real webhook handling, not a sandbox demo.
GPT-4 with a system prompt tuned for UK legal context.
Whisper for voice transcription; language auto-detection so users in any language get a response in the same language.
Production-grade Node.js backend with stateful conversation handling.

Private Construction Client
iOS app for construction site inspection and punch-list management. Field teams create projects, log defects with photos, assign and track issues, and export branded PDF reports — replacing paper-based snagging workflows.

Private Client MVP
Bike-matching iOS app. Built a guided preference questionnaire and recommendation engine that surfaces bikes from a catalog based on suspension, riding style, frame, and price.
