Japan · The Discipline Era · 2016 – 2019
Led a 15-member distributed engineering team across Japan, China, and India to build Cart & Checkout microservices for Uniqlo's global e-commerce platform. 40+ APIs, 1,000+ orders per minute. IaC with Terraform. SLI/SLO/SLA monitoring. The scale was global; the culture we built was deeply human.
A brief return to Pakistan between Japan chapters. Led design and development of a trip planning platform — multi-leg layovers, real-time notifications, personalized journeys, and a gamified loyalty engine. Introduced TDD and CI practices that became team standards.
Led end-to-end redesign of Rakuten Travel's next-generation search engine — multilingual (CJK), context-sensitive, location-aware search at scale. The discipline of Japan entered my engineering DNA here. 100ms query SLA. TDD at 99% code coverage. A team culture where precision wasn't a goal — it was the baseline.
Pakistan · The Foundation Era · 2008 – 2016
Museum-focused enterprise software — building a secure, scalable Enterprise Audit Trail system for preserving digital traceability of rare and high-value assets: books, paintings, sculptures, historical objects. A niche domain that demanded forensic-grade precision. Taught me that every system is ultimately about trust.
Mission-critical payment systems for global networks. Worked on high-throughput OLTP systems supporting Visa, Mastercard, Discover, and American Express across North America, Europe, Latin America, the Middle East, and Africa. Architected a centralized Data Vault Service with HSM-integrated cryptography for PCI-DSS and GDPR compliance. This is where I learned real ownership — not of tasks, but of outcomes.
