EXPERIENCE
Full Stack Engineer Sep 2025 -- Present
Buildapps Remote
• Built production Node.js services on Strapi 5 / PostgreSQL across 5 backend domains (valuation, booking, KYC,
nearby-branch search, Firebase auth): multi-step valuation, transaction and pricing lifecycle, and custom REST endpoints
rather than CMS-only content types
• Implemented booking as a backend service: calendar-slot generation, compare-and-set slot locking, Google Calendar sync
after a booking is secured, plus 3 customer flows (history, reschedule, cancellation)
• Added nearby-branch search on PostgreSQL (Haversine distance, paging, active-branch filtering) so clients can discover
dealers by location
• Integrated Persona KYC in Node.js (HMAC-signed webhooks, inquiry status mapping, age checks that gate evidence
writes) and Firebase token authentication so KYC and profile updates stay consistent across the API
• Extended a NestJS/Express staff-allocation API used by 40+ staff with time-off requests, company day-offs, Google
Calendar out-of-office sync, and manager reassignment when an employee had subordinates
• Independently owned 5 projects end-to-end (2 interactive gaming sites and 3 medical platforms); contributed to 5+
additional projects within the engineering team
• Designed 2 reusable Next.js clinic templates on a shared Strapi/PostgreSQL CMS, deployed across 17 clinics by
configuration rather than separate codebases; added contact and job-application email on the same stack
• Shipped Next.js game/content sites including an Arabic RTL microsite that reached 5,000+ user interactions; improved
page load speed by 15-30% through asset optimization, code splitting, and lazy loading; added a custom reviews model in
Strapi
• Collaborated with clients, senior developers, and SEO specialists to translate business requirements into production-ready
solutions
