I provide a long-running PHP Laravel developer team that ships SaaS, CRM, marketplaces and admin tools. 7,000+ hours worked, 200+ PHP Laravel developer projects delivered, 100% Job Success Score, Top Rated Plus. As COO I scope, plan and oversee every PHP Laravel developer engagement we sign. I qualify the brief, run discovery, match the right engineers and own commercial relationships. My team owns the code. Why hire my team: - 20+ years of PHP Laravel developer delivery - 200+ PHP Laravel developer, Full Stack Laravel, Laravel Vue and PHP React projects shipped - Long-term retainers (3 - 10+ years) The PHP Laravel developer team I run is a full PHP Developer and Backend Developer bench. Every PHP Developer on it works in Laravel, MySQL and Redis with RBAC, audit trails, Stripe billing, queues and WebSocket real-time, so when a client needs a PHP Developer or a Backend Developer who owns the data model and the API, that is the seat I staff. The Backend Developer side covers schema design, REST and GraphQL APIs, background jobs and Nylas, Mailgun and Stripe integrations. On the frontend my Vue.js Developer and React Developer engineers pair with that backend. A Vue.js Developer takes admin panels, dashboards and multi-tenant SPAs on Inertia.js, Vue 3 and Pinia; a React Developer takes SaaS dashboards, marketplaces and content platforms on React + Next.js. Laravel Vue is what we reach for when a project needs a clean PHP backend with a reactive SPA. PHP React is the go-to when Laravel pairs with React + Next.js, with react node services and a javascript developer mindset across both sides. Our Full Stack Laravel team owns systems end-to-end - a Laravel + PHP backend paired with a Vue or React frontend, MySQL, APIs and AWS. Clients hire a Full Stack Laravel team instead of splitting backend and frontend specialists. Adjacent Full Stack Laravel: full stack web developer rebuilds, full stack php delivery, python full stack developer pairings for data and AI, full stack developer ai and full stack developer react funnels. A lot of the work is line-of-business systems, so I also staff a dedicated CRM Developer and ERP Developer. A CRM Developer rebuilds messy spreadsheet-and-email workflows into a single Laravel CRM with pipelines, roles and reporting; an ERP Developer wires registration, billing, inventory, lab and back-office modules into one platform with shared RBAC and audit. We have shipped a clinic ERP with cashier, doctor and lab desks and a CRM rebuild that ripped out a legacy Gutenberg setup. The CRM Developer and ERP Developer seats sit on the same Laravel core. Above the role labels, every engineer is a Software Developer first. That Software Developer discipline - clean architecture, code review, predictable deploys, tests - keeps a multi-month build stable and is what a client really buys when they hire a Software Developer through me. Migrations the team handles often: ruby on rails moved onto Laravel + React or Laravel Vue, an android developer hand-off when a backend feeds a mobile app, a flutter laravel companion when mobile is on the roadmap, a wordpress developer track for storefront and CMS migrations, and php laravel react rebuilds for clients outgrowing a Gutenberg setup. Clients hire me when they need: - a PHP Developer or Backend Developer who owns the data model, API and infra - a Vue.js Developer or React Developer to pair with a Laravel backend - a CRM Developer for pipelines, roles and reporting on Laravel - an ERP Developer for registration, billing, inventory and back-office modules - a Software Developer team for SaaS, marketplace or CRM products - a Full Stack Laravel team that owns frontend, infra and deploys - a wordpress developer hand-off and a long-term web developer and website design partner Recent work my team shipped: - Identity-verification SaaS. Backend Developer + Full Stack Laravel. Laravel + Node.js real-time, MySQL + Redis. 4K+ DAU, 1M+ checks via Developer API. - Multi-currency Voting SaaS. Full Stack Laravel / PHP React. Laravel + MySQL, real-time vote locking, Stripe payouts. 2M+ users in 10 countries, $2.5M+ revenue. - Clinic ERP. ERP Developer / Backend Developer. React + Next.js, Laravel, Node.js, Redis, AWS. Registration, cashier, doctor, lab desks, 500 patients/day. - Education B2B platform. Vue.js Developer + React Developer. Laravel 8, Vue.js admin, React portals, CKEditor, Stripe. Hierarchical content editor, student seats. - CRM rebuild on Laravel. CRM Developer / PHP Developer. Legacy WordPress + Gutenberg ripped out, photoshop assets, photographer briefs and product photography pipelines re-routed into a custom Laravel CMS with Nylas and Stripe. The COO hat keeps multi-month delivery predictable. Need a PHP Developer, Backend Developer, Vue.js Developer, React Developer, CRM Developer, ERP Developer or Software Developer team that ships on time and stays long-term - let's talk.

$87M in client revenue. 150+ projects shipped. Top 1% on Upwork. Not a pitch. Just receipts. I build web apps that actually work at scale. The kind that handle a million users without breaking a sweat. Django backends, React and Next.js frontends, and lately, a lot of AI integration work with LLMs and ChatGPT APIs. Here's what I bring to the table: ▸ Full-stack development (Django, Python, React, Next.js, MERN) ▸ AI and LLM integration (OpenAI, RAG systems, custom chatbots) ▸ SaaS architecture built for growth ▸ REST APIs and microservices that don't fall apart 73% of my clients come back for more work. Some have been with me for years. I think that says more than any badge. 10 years in, I've learned what separates good projects from disasters. Clear communication. No surprises. Shipping on time. Treating your business like my own. If you're building something serious and need someone who can lead the technical side, let's talk. Send me a message with your project details.

I have more than 15 years of programming experience. As a freelancer, I have broad experience: I developed web (ASP.NET, Python, PHP), desktop (C++, C#, Python — Linux and Windows) and mobile (Android — Java, C++) applications. I list here some of my jobs. C#: * clubspeed.com — a large software suite for family entertainment clubs; included C# code (80%), including CoreApi and ASP.NET Razor, plus PHP (Laravel) and Node.js code (for low-level car racing control tasks). I developed it as a team member. * qadra.com — a financial company; C# code (80%), Python (some microservices are Python/Flask based, 20% of code), AWS-hosted with Docker containers and Lambdas. I developed it as a team member. * enven.nl — implemented from scratch their non-public partners portal: ASP.NET Razor and some CoreApi endpoints. * ASP.NET website for house rentals. * ASP.NET website for remote control of a robotic device via a WebSocket connection. * Vegetable-oil plant automation desktop program (C# + WinCC). Python: * Embeddable fact-checking chat that uses the LangGraph framework to implement a customizable LLM/AI backend (OpenAI, DeepSeek, Hugging Face, or Ollama). It allows administrators to embed the component in their websites so users can ask questions about facts described in articles and verify whether facts listed in an article are true. It included agentic code and many external APIs to check facts (not just asking an LLM), and even computer vision to inspect website photos (OpenCV). Backend is FastAPI. * AI/LLM-based ad selection for a website (FastAPI and LangGraph). It processes website text or chat messages and selects ads of different types related to the content. It contains SDKs for embedding ads on many platforms, including Go, React, and plain HTML. * Polish-language training software, based on Django and LangGraph. * Many small projects: desktop scripts, web scraping (Selenium and related tools), and simple AI agents. C++: * Factory equipment monitoring system (Ubuntu Linux, custom server over TCP/IP, web interface in PHP). * Many small projects, some of which are mentioned in reviews on this profile; many are non-public. * Powerful software for automated ad submission on social networks (massive bots that send millions of messages). PHP: * 20+ websites — without CMS, with my own CMS, and with open-source Drupal, WordPress and Joomla CMSs. * Backends for Android applications. Android: * SOCKS5 proxy application that allows sharing mobile VPN with non-mobile clients via the SOCKS protocol. * Many WebView-based "business card" applications. * Dating-related applications, including erotic puzzles. Human emulation: * Spam bots — I cannot provide a specific list of such software for legal reasons. * Automatic checkout on eBay and similar websites. * PayPal automatic payments. * Data scraping, including air tickets and goods in online stores. Reverse engineering — I cannot provide a specific list of reverse-engineered software for legal reasons. * Java bytecode reverse engineering, including Android. * .NET bytecode reverse engineering. * Machine code for 32-bit and 64-bit x86 and ARM CPUs. Assembler: * High-performance cryptographic library for x86\_64 CPUs.
