2020 – 2021 / FOUNDATIONS IN CORE PHP & CODEIGNITER
Building Core PHP, CodeIgniter & Database Architecture

Started hands-on engineering at Ghani Business Solutions, building production systems including a Battery Management System, Restaurant POS with receipt printers, and a comprehensive School Management System. Working with raw relational database normalization, fee voucher generation (Challan), and granular roles & permissions taught me early how to design schemas that withstand real transactional loads.

2021 – 2026 / TECHNICAL LEAD AT NEXTAPP.IS & PRODUCTION SAAS
Promoted to Technical Lead: Delivering 10+ Production SaaS Platforms

Promoted from PHP Developer to Technical Lead at NextApp.is. Led a cross-functional engineering team, drove architecture decisions, enforced rigorous code reviews, and successfully shipped 10+ production SaaS platforms. Key systems included ALF POS (serving 10,000+ active clients globally processing millions in daily transactions), Wapply (WhatsApp Marketing SaaS with real-time WebSockets), and SG Collectors (international B2B debt collection CRM). Integrated complex payment gateways (Stripe, JazzCash, EasyPaisa, ValorPaytech, Elavon) and cloud infrastructure (AWS S3/SNS, Redis, Firebase).

2026 – PRESENT / ENTERPRISE MULTI-TENANCY, STRIPE BILLING & AI
Advanced Multi-Tenant SaaS, Stripe Billing & Multi-LLM Pipelines

At Microvision IT Solutions, engineered the multi-tenancy engine (domain-based tenant isolation & company-scoped queries) and complete Stripe subscription billing system from scratch for Go2Sell (UAE-market multi-tenant SaaS e-commerce). Built Go2Sell Activate, integrating multi-provider LLMs (OpenAI, Anthropic Claude, Google Gemini) and Google Imagen/Veo with Meta Graph API for scheduled automated campaign publishing. Authored the complete backend architecture for a UAE Football Association subscription platform featuring 12 sub-roles and Stripe Connect revenue-split billing.

How I work

01. Multi-Tenant Isolation & Clean Architecture

Zero data leaks across tenant bounds. Domain-based tenant routing with stancl/tenancy, company-scoped queries, and custom super-admin governance panels.

02. Bulletproof Stripe & Payment Lifecycles

Comprehensive subscription lifecycles: trials, pause/resume/cancel, Checkout sessions, Billing Portal, Stripe Connect splits, and idempotent webhook reconciliation commands.

03. Laravel Octane & High-Throughput APIs

Sub-50ms API responses powered by Laravel Octane, Redis connection caching, Elasticsearch full-text search, and automated background queue workers.

04. Automated Pest & PHPUnit Testing

Every mission-critical endpoint, billing event, and access guard is covered by comprehensive automated tests and living Scribe API documentation.
