I build the backend systems and API integrations that power SaaS products — clean architecture, reliable data sync, and third-party connections that actually work at scale.
I'm Wadud — a backend and integrations engineer with over 9 years building production-grade systems. I specialize in Laravel, PHP, and RESTful API design, with deep experience connecting platforms through third-party integrations that are reliable, accurate, and maintainable.
I've led engineering teams across Norway, Ireland, and Israel — working remotely with SaaS companies to migrate legacy systems, build microservice architectures, and reduce infrastructure costs. The features I've shipped have directly contributed to 21% revenue growth and 30% downtime reduction in production environments.
I care about clean code, ownership, and impact. I don't just write features — I think in systems.
I design APIs and integration layers with third-party developers and downstream consumers in mind — not just internal use.
I've resolved critical N+1 query chains, implemented Redis caching strategies, and right-sized cloud infrastructure to cut costs by 30%.
100% remote since 2020. I communicate clearly, take ownership without micromanagement, and ship consistently across timezones.
From system design and database schema to API deployment and production debugging — I own the full integration lifecycle.
Chosen for real-world production use, not resume padding.
Not generalist breadth — specific, battle-tested depth in the areas that matter.
Designing, building, and maintaining integrations with platforms like Shopify, WooCommerce, WordPress, Zapier, and enterprise ERPs. End-to-end ownership from API contract to production sync.
Building developer-facing RESTful APIs with clean contracts, versioning strategies, and documentation that external teams can actually use. Includes AJAX/JSON/JSONP patterns and webhook delivery.
Migrating monoliths to microservices, designing event-driven middleware, and architecting systems from scratch for MVP-stage SaaS products. Built to scale, not just to ship.
Diagnosing and resolving N+1 queries, duplicate DB calls, and slow integration payloads. Implementing caching with Redis and right-sizing infrastructure — cut monthly AWS costs 30%.
Working across multi-product SaaS environments, building reusable integration layers, and maintaining plugin ecosystems for e-commerce platforms at scale.
Led teams of up to 8 across developers, QA, BA, and PM. Introduced Agile practices, Git Flow, and cross-timezone remote workflows that actually ship.
Real impact, real systems, real numbers.
Architecting public APIs and third-party integrations for an Oil & Gas SaaS platform, connecting AI data pipelines and external services via REST and event-driven architecture.
Designing full API surface from scratch — system design, database schema, contract definition — for MVP-stage product.
Automating multi-step stakeholder workflows by integrating third-party platforms and services, eliminating manual processing overhead.
Audited and refactored a large-scale PHP/Laravel SaaS codebase — applied SOLID principles to improve integration layer reliability and scalability.
Resolved critical database performance issues (N+1, missing indexes, nested queries) using eager loading and Redis caching, improving API response times across integration endpoints.
Reduced monthly AWS infrastructure costs by 30% by right-sizing cloud resources to match actual system load.
Designed and developed public RESTful API endpoints for a SaaS platform serving enterprise clients — authored API contracts and documentation for third-party developer consumption.
Built and maintained integrations consuming SOAP and REST APIs with reliable payload mapping, error handling, and production-level data syncing.
Led a team of 8 (developers, QA, BA, PM) across sprint planning, PR reviews, and Git workflows in a fully remote environment.
Architected a full microservice replacement for a legacy CodeIgniter monolith using Laravel — reduced system downtime by 30% and contributed directly to 21% revenue growth.
Built an event-driven middleware integration with Infor M3 ERP enabling real-time sync of orders, inventory, and customer records.
Designed WooCommerce and WordPress-compatible integration endpoints for seamless e-commerce data exchange.
Built RESTful APIs for Telenor Myanmar's Eagle mobile app — owned full integration lifecycle from JSON contract definition to production debugging.
Developed a fraud-detection integration for GrameenPhone's e-commerce platform (millions of users), analyzing purchase behavior via API-driven pipelines to prevent fraudulent orders in real time.
Developed full-stack web features using PHP frameworks under senior engineer guidance, managing Git workflows and responding to code review feedback.
Delivered client-facing training, onboarding documentation, and technical manuals for system handovers.
Selected from 9 years of production work.
Led the complete migration of a legacy monolith to a Laravel microservice architecture. Designed the full RESTful API surface and built event-driven ERP middleware for real-time data sync.
Built an API-driven fraud prevention integration for a major e-commerce platform serving millions of users, analyzing customer purchase behavior and demographic data to block fraudulent orders in real time.
Designed and delivered the complete RESTful API backend for Telenor Myanmar's Eagle mobile application — from JSON contract definition and endpoint design to production deployment and ongoing debugging support.
Full audit and architectural overhaul of a high-traffic Laravel SaaS codebase. Resolved N+1 queries, implemented Redis caching, and right-sized AWS infrastructure — cutting monthly costs by 30%.
Designed and maintained a suite of public RESTful API endpoints for enterprise SaaS clients in Norway, including SOAP/REST third-party integrations, full API documentation, and team leadership across 8 engineers.
Led a 6-person cross-functional team to design and deliver a complete backend integration solution for a global maritime welfare organization — from technical planning and API design through to release.
I'm open to senior backend and integrations engineering roles at SaaS companies — especially where API design, third-party integrations, and Laravel are at the core of the product.
