Clearly an experienced developer. Will seek clarification on all the important points, ask the important questions, etc. so you don't have to worry about understating anything in tickets - then executes and delivers quickly, in one go. Overall impressed with Maksym's professionalism and quality.

Generating a Cost Estimator Website: Need Efficient Full Stack Developer
Maks did exceptional work on a complex custom SaaS project that I was able to take to market. He’s solution oriented, detail oriented, a clear communicator, and truly committed to quality. He quickly grasped the big-picture vision and turned my idea into a polished product. Communication was excellent throughout, and he consistently delivered above expectations.
I’ll definitely be hiring Maks again!
Genuinely, if you are considering the opportunity to hire him, I would love to be a reference (I live in California, please ask Maks to connect us and I can show you his work).

Koper, Slovenia - 7:16 am local time
If you are looking for a Full Stack Developer to take ownership of your architecture, security, and deployment, you are in the right place.
🚀 Why Clients Choose Me as their Full Stack Developer:
✅ Business-First Engineering: Unlike a standard Web Developer who just writes code, I focus on your ROI. I build systems that solve business problems, from complex API integrations to custom dashboards.
✅ Symfony & Laravel Expert: I specialize in high-end PHP frameworks (Symfony/Laravel) and modern frontend stacks.
✅ Scalable Architecture: My solutions are built to scale. I handle Database Architecture and DevOps (AWS/Docker) so you don't have to hire a separate Backend Developer.
Core Services & Expertise
As your dedicated Full Stack Developer, I cover the entire product lifecycle:
1. Enterprise Web Development (Symfony & PHP) I provide robust Full Stack Developer services using PHP 8.4, Laravel, and Symfony. Whether you need a legacy system modernization or a new SaaS platform, I deliver clean, documented code.
Backend Developer logic that handles complex data processing.
API Development (REST/GraphQL) for mobile and web apps.
Node.js integration for real-time features.
2. Modern Frontend & UI (React Developer) I act as a lead React Developer to build responsive, lightning-fast interfaces.
React Developer expertise for Single Page Applications (SPA).
Front End Developer mastery including HTML5, CSS, and Web Design implementation.
Experience integrating with React Native Developer teams to ensure web/mobile parity.
3. E-Commerce & CMS (WordPress Developer) While I specialize in custom software, I also provide high-level WordPress Developer services for enterprise needs.
Custom WordPress Developer plugin creation and theme development.
WooCommerce and Shopify Developer API integrations.
Performance optimization and technical SEO implementation.
My "Full Stack Developer" Process
When you hire me as your Full Stack Developer, you get a transparent, agile workflow:
Discovery: I analyze your needs better than a typical Web Developer, ensuring we pick the right stack (e.g., deciding between a Python Developer approach or a PHP solution).
Architecture: I design the database (MySQL/PostgreSQL) and infrastructure.
Development: Agile sprints as your Full Stack Developer and React Developer.
Deployment: CI/CD pipelines, Docker containers, and AWS setup.
Technical Stack & Capabilities
To ensure I can serve as a comprehensive Full Stack Developer, I maintain proficiency and familiarity across a wide range of technologies found in modern Web Developer environments:
Backend: PHP (Symfony, Laravel), Node.js, Python Developer (Scripting & Scraping integrations).
Frontend: React Developer tools, JavaScript, Angular (Maintenance), Web Design principles.
Mobile Context: Experience architecting APIs consumed by a Mobile App Developer (iOS/Android) or Flutter Developer.
CMS: Enterprise WordPress Developer workflows, Shopify Developer integrations.
Infrastructure: AWS, Docker, Linux, Database Design.
Case Studies & Results
SaaS Platform: Acted as Lead Full Stack Developer for a B2B platform, handling 10k+ daily transactions.
Legacy Migration: Replaced an outdated system with a Symfony/React architecture, improving performance by 300%—a result a standard Web Developer rarely achieves.
E-Commerce API: Built a custom middleware connecting a WordPress Developer site to an ERP system.
Frequently Asked Questions
Q: Can you work with my existing team? A: Yes. I often work alongside a dedicated Front End Developer, React Native Developer, or Mobile App Developer. I can also act as a CTO figure for smaller teams.
Q: Do you handle design? A: I have strong Web Design skills for UI/UX implementation. If you have a graphic designer, I will implement their vision pixel-perfectly as your Front End Developer.
Q: Why choose you over a generic agency? A: An agency assigns you a junior Web Developer. With me, you get a senior Full Stack Developer and React Developer with 15+ years of proven success.
