About

A doctor in a two-room clinic in India and a TESCO store colleague starting a shift in the UK have nothing in common. Both their mornings run on software I built. That contrast is my career right now. 𝗧𝗛𝗘 𝗗𝗔𝗬 𝗝𝗢𝗕- Senior Architect-II at Tesco I own ~20+ micro-services behind the platform that generates ~𝟰.𝟱𝗠 shifts a week for 𝟰𝟬𝟬,𝟬𝟬𝟬+ colleagues across 𝟰,𝟬𝟬𝟬+ Tesco stores - scheduling, rostering, resource planning. The unglamorous machinery deciding whether someone gets the hours they need or a rota that wrecks their week. We lifted scheduling accuracy 𝟰-𝟱%, worth around ~£1.5M a year cost save- and fewer last-minute call-ins. I lead 10+ engineers, own the architecture decisions and design reviews, and spend much of my week with product and business teams. Fifteen years in, I'm convinced the hard part of architecture is rarely the technology. It's understanding the problem well enough to know which trade-off you're really making. 𝗧𝗛𝗘 𝗣𝗔𝗥𝗧 𝗜 𝗕𝗨𝗜𝗟𝗧 𝗠𝗬𝗦𝗘𝗟𝗙 as Co-Founder 𝗖𝗼𝗿𝗽𝗫 (corpxapp.com) - a professional network that brings like-minded working professionals together to connect, grow and Xchange. Corporate-email verification means the person on the other side is real. Same Java and Spring Boot backend, Flutter and native Android, on Google Play and web and Its growing so fast to reach the big milestone and getting huge community. 𝗦𝗲𝘃𝗮𝗖𝗮𝗿𝗲 (sevacareapp.com) - A Healthcare operating system already running live in hospitals. Built for multi-speciality hospitals, clinics and nursing homes, scaling to 200+ beds. I'm its only architect and engineer: multi-tenant Java and Spring Boot with a Flutter front end, per-hospital schema isolation, AES-256-GCM encryption with tenant-managed keys, append-only audit logging. Enterprise security built by one person, because patient data deserves it in a two-room clinic as much as a 200-bed ward. 12+ roles/modules: live token queueing so patients aren't guessing in a corridor, prescriptions over WhatsApp, pharmacy, labs, billing, analytics. Six languages, because a receptionist shouldn't have to work in English. Hospitals run their whole day on it. Building a product alone teaches you what enterprise work cannot. You feel every shortcut you took. You take the support call yourself. It made me a sharper architect, not a distracted one.
