Hire the Best Laravel Developers
in Poland

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.

Focusing on long-term opportunities 🙂 Some facts about me: - 10+ years of experience / SaaS, High Load products, Healthcare, Integrations - Focused stack: PHP / Laravel, AWS, React, Vue, React Native, NextJS / Caching, Infrastructure - Free Consultation / Providing support / Clean code / NDA signing - Worked with clients based in different countries and timezones

Full-stack developer with 15+ years of experience, focused on Laravel and Vue.js, along with SQL, Docker, microservices, and REST API work. Most of my projects run end to end, so I'm usually involved in the architecture, the coding, the testing, and keeping things stable in production. I lean on test-driven development and try to keep the codebase clean and easy to maintain, so it stays pleasant to work with over time. I also work with LLM and AI driven features, and I use AI tools in my own day to day workflow. On one of my current projects I build agentic workflows and agent orchestration directly into the platform, so I'm comfortable putting LLMs into real production applications rather than just experimenting with them. Some recent work: a Kubernetes based microservices platform for a solar-panel rental business, a production planning system for a cardboard factory that schedules jobs around real machine constraints, and an event and congress platform covering registration, abstract submission, accommodation, RFID badging, and certificate generation. So far my Upwork contracts have all finished at 5.0, which I'm happy about. I mainly enjoy longer term collaborations where I can really get to know a product. If that fits what you need, feel free to reach out and tell me a bit about it. Core stack: PHP, Laravel, Eloquent, Vue.js, Inertia.js, Livewire, MySQL, REST APIs, OAuth2, Docker, Kubernetes, PHPUnit, Git, JavaScript, Angular, LLM Integration.

Hi there! 👋 As a dedicated Full Stack Developer and SaaS Developer, I focus on engineering Custom Business Applications and production-ready software that holds up under real-world usage. My commitment to quality and client satisfaction is reflected in my 100% Job Success score on Upwork. My work sits at the intersection of software developer, web developer, and SaaS platform builder, with a deep attention to scalability, performance, and long-term maintainability. As a Full Stack Developer, I take ownership of systems end-to-end, pairing robust backend architecture with clean, modern interfaces. My frontend work is typically React-based, and I often collaborate with or replace traditional React developer or web developer setups by owning both frontend and backend in a single, coherent system. In the past few years, I’ve integrated an AI-first mindset into my workflow, using Python to build intelligent automations and LLM-driven features. As a SaaS Developer, I help companies design, build, and scale SaaS products, internal tools, and API-driven web applications intended for long-term use. My experience as both a software developer and SaaS development expert allows me to think beyond features and focus on architecture, reliability, and operational stability from day one. Many of the platforms I build include Healthcare applications, CRM, ERP, and custom portals where permissions, data integrity, and business rules are critical. In my day-to-day work, I design and implement backend services, APIs, and data models that power SaaS and complex web applications. I regularly work with Node.js, PHP (Laravel), and Python, drawing on my background as a Python developer to build scalable services, background jobs, and asynchronous workflows that perform reliably in production. As a Full Stack Developer and CTO, I ensure these backend systems integrate cleanly with frontend applications and third-party APIs. When required, I support react developer and mobile app developer workflows to deliver seamless user experiences. This end-to-end ownership is a key reason clients bring me in as a Full Stack Developer rather than splitting work across multiple roles. A significant portion of my work involves building internal platforms and API-first systems. In these projects, I often collaborate with teams focused on saas marketing by designing clean data pipelines and backend logic. My versatility as a wordpress developer and web developer allows me to bridge the gap between marketing sites and complex backend systems, including integrations with legacy CMS or WordPress-based systems when required. Clients typically work with me when they need: a Full Stack Developer laravel who can own frontend and backend a SaaS Developer who understands long-term scalability constraints a Backend Developer experienced with Node.js, PHP, and Python mobile app developer and react developer experience as a software developer backend services built with Node.js or Python by an experienced Python developer web applications with complex workflows from a senior web developer a wordpress developer for custom theme/plugin logic and API integrations SaaS platforms designed to support growth and saas marketing data needs MVPs that can realistically evolve into long-term SaaS products A large part of my work as a Full Stack Developer, SaaS Developer, and Backend Developer focuses on: -multi-role dashboards and internal tools (CRM & ERP) -authentication, authorization, and permissions -API-first backend system design -integrations with external platforms, including WordPress systems -Secure cloud solutions using AWS My core work as a Backend Developer and Full Stack Developer, CTO covers: backend services built with Node.js, PHP, and Python APIs, background jobs, and integrations databases such as PostgreSQL and MySQL modern stacks using tools like React, Vue.js, and Laravel AI-enabled backend features where they add real business value I regularly work on MVP builds as a SaaS Developer, with a focus on solid backend foundations and avoiding short-lived prototypes. Based on scope and timing, I work hands-on as a Full Stack Developer, SaaS Developer, and Backend Developer. Long-term results come from clarity and intentional system design. I focus on delivering software that teams can confidently run, maintain, and scale.
