Firas S.

Senior Full-Stack Developer & Tech Lead | WordPress, PHP, Vue, AI

Senior full-stack developer & technical project manager with 15 years of experience. I build and ship custom web platforms for clients in Switzerland, the US, the UK and Canada — I own projects end-to-end: scoping, architecture, team coordination, delivery, and I stay hands-on in the critical code. What I build: - Custom WordPress & WooCommerce — plugins, themes, multi-site setups, PIMs, payment integrations at any complexity - CodeIgniter 4 and PHP back-ends, REST & GraphQL APIs - Vue.js, Node.js and TypeScript front-ends - E-commerce at scale — Stripe Connect marketplaces, Shopify/Liquid, PayPal, Bitcoin/crypto gateways - AI-powered features using OpenAI, Claude and Gemini APIs — content generation, classification, workflow automation - Cross-platform mobile apps (iOS + Android) that ship alongside the web product - Long-term maintenance and technical partnership — not just one-and-done builds How I work: I'm equally comfortable working solo or inside a team, as lead or as contributor, on one project or several in parallel. I use AI-assisted development workflows (Claude Code, Antigravity) to move faster without ever losing hands-on control of the codebase. If I say I can do it, I get it done — my 100% Job Success Score across 46+ contracts is a fair representation of that. Things I've built: - Operations platforms with companion iOS + Android mobile apps — staff and shift management, on-site clock-in, QR-code task scanning, automated reporting - PHP project-management systems with full accounting-software integration (Zoho Books and similar) - Custom live-auction marketplaces with crypto and alternative payment gateways - Multi-site WooCommerce architectures with centralised product information management - API integration layers for video, publishing and enterprise workflows - Numerous WordPress/WooCommerce stores and custom CRMs for international clients Send me the brief — happy to talk through what you need and where I can help.
