Most people schedule a meeting to discuss the problem. I'd rather solve it and send you an update. I take ownership of content and SEO operations - the publishing, updates, QA, and maintenance work that keeps your sites running - so you can stop managing it. My long-term clients all say some version of the same thing: "once Adrian takes over, I stop worrying about it." 🏆 Top Rated | 98% Job Success | 70+ projects | 5+ years Proof, not promises: → Ran content operations across a 100+ domain affiliate portfolio (iGaming) - weekly update cycles, ranking maintenance, full QA, zero errors reaching production → Audited a 2M+ article site with no CMS access - found 172 critical issues, delivered a phased recovery plan the client is now implementing (with me executing inside the CMS) → Cut a marketing agency's content production time from 5 days to 2 by rebuilding their workflow - then documented everything in an SOP library with Loom walkthroughs → Currently managing SEO and content operations across multiple client properties: technical fixes, schema, internal linking, PageSpeed, publishing How I work: I work in two formats. Monthly ownership - you hand me a defined area (a site, a portfolio, a publishing operation) and I run it: weekly delivery, written reports, issues flagged before they become problems. Or fixed-scope audits - you get a prioritized, phased action plan any developer or VA can execute; if you want, I execute it myself. Fully async. No standups, no status calls, no chasing. If I have a question, you'll get a message. If something's wrong, you'll hear it from me first. Loom walkthroughs when something needs showing rather than telling. Good fit if you: run an affiliate portfolio, an agency, or a content-heavy site and want the operations off your plate - permanently, not project by project.

Need a Laravel or Symfony developer who can build SaaS billing that survives production? I specialize in Stripe subscriptions, multi-tenant architecture, and AI-powered features. I build and maintain high-load SaaS platforms — where payments, billing, and AI integrations just can't fail. Launching a subscription product? Adding AI to your existing app? Scaling a multi-tenant system, or inherited a messy legacy codebase? That's exactly what I do. Laravel/Symfony on the backend, Vue.js/Nuxt.js on the front — built to last. 🎯 Core Areas of Expertise 💳 Stripe & Subscription Systems Full subscription lifecycle management: asynchronous webhooks handling, metered billing, upgrades/downgrades, dunning management, and Stripe Connect for marketplaces. 🏢 Multi-Tenant SaaS Architecture Robust tenant isolation strategies (single-database with scoped scopes or multi-database systems), dynamic subdomains, and clean infrastructure boundaries using Docker and Caddy. 🏗️ Long-Lived Enterprise Systems Deep work with large-scale Laravel and Symfony applications using Domain-Driven Design (DDD). I design clean architectures that remain maintainable years down the road. 🔌 High-Performance APIs & Integrations Designing scalable REST and GraphQL backends optimized for high concurrency, webhooks processing, and clean consumption by frontend layers. 🔐 Security & Data Resilience Encryption at rest, strict Role-Based Access Control (RBAC), secure OAuth/token authentication, and automated backup strategies. 🛠️ Legacy System Takeovers & Maintenance I don't just patch symptoms; I audit and fix the root cause. If you have a fragile, unoptimized application that frequently drops connections, chokes on database queries, or fails during high-traffic windows, I step in to modernize the code, optimize the infrastructure, and stay on as your long-term tech partner. 📊 Proven Track Record 8+ years of engineering production-grade PHP systems (Laravel, Symfony, Go). 2,000+ logged hours on Upwork with a flawless 5-star rating across all contracts. Consistent history of long-term, multi-year client partnerships — not just one-off gig builds. Expert workflow utilizing cutting-edge tools (Docker, PHPStorm, PHPStan, Pest, Claude Code) for automated quality control and rapid deployment. I read your codebase thoroughly before making a single change. I communicate clearly, document everything, and never disappear mid-project. If you are looking for a reliable, product-minded engineer to take your platform to the next level, send me a message. Let’s jump on a quick call, audit your current challenges, and outline a concrete roadmap.
