I’m Ramiz Ur Rehman, a Senior Full Stack Engineer and Technical Lead who has been shipping ride-hailing, FinTech, travel, healthcare and ERP platforms since 2017. My work runs from monolith-to-microservices migrations to compliance engines that push 150K+ invoices a day.
Broke a live ride-hailing monolith into domain services (users, rides, promotions, payments) that talk over Kafka, run in Docker and report into the ELK stack. Alongside it: a revamped driver promotions engine and an automated driver onboarding flow.
An end-to-end hotel and travel booking platform for AB Transportation. It merges several hotel suppliers and direct hotel contracts into a single search, makes B2B agency commercials fully configurable, and takes payments through MyFatoorah. Transfer bookings are idempotent and prices are multi-currency.
High-throughput e-invoicing gateway for Saudi Arabia’s ZATCA mandate, built on Spring Boot and processing more than 150,000 invoices every day.
Retail ecosystem connecting payment gateways, WhatsApp ordering, POS, B2B sales and FBR tax reporting across web and mobile, plus a cashier-less store prototype.
Web and mobile clinic records with an interactive tooth chart, treatment history, prescriptions and appointments, plus a native iOS app on Google Cloud.
Real-time invoice reporting to Pakistan’s FBR, delivered for LedgerSMB, Smart Vendi and enterprise clients, so every sale reaches the tax authority automatically.
Custom Odoo modules that bend inventory, sales, purchasing, HR and reporting to fit how each client actually works.
Multi-language CMS that lets non-developers launch complete affiliate websites through structured data entry.
Before anyone writes a line of code, I map the boundaries: which service owns which data, what moves through events, and where things can fail. This diagram shows the shape of the ride-hailing platform I helped break apart.
