Stripe payment flow review & cleanup
Not only great developer, but also great sparring partner. Really knows what is needed, and can clearly explain why, even though I think initially otherwise. Also code committed is clean and compact.

Need a quick React / Next.js Fix Landing Page Error
Rostyslav quickly identified and fixed a Next.js build issue that was preventing our landing page from loading. Communication was excellent, turnaround was fast, and the fix was implemented cleanly. Strong React/Next.js troubleshooting skills and very easy to work with. Would happily work with him again.

If your current project is stuck because of messy APIs or poor Software Architecture & Design, I step in. My job as a Senior Full Stack Developer is taking an idea and making it a running Web Application. I focus on getting things done efficiently, whether you are building a complicated e-commerce platform or need specialized AI Integration for proprietary data. I work hard to make the entire development cycle clear for everyone involved. A good web developer needs to handle both the frontend experience and the back end logic so that the whole thing runs smoothly in production. If your team is looking for a Full Stack Developer who can deliver quality code using technologies like JavaScript, CSS, and HTML5 right away, we should talk. I am a reliable full stack developer helping clients build better digital tools.
Over 12+ years as a web developer, I have been building systems from the ground up. As an experienced Full Stack Developer, my background spans multiple core areas of software development. I work across stacks including Django and Laravel backend logic. For example, I spent over 5 years with Python as a full stack developer, working on 20+ backends that use Django or pure Python for Software Development. When building these services, I bring expertise in API Integration and using technologies like MySQL and Git from day one. My work covers everything from the web design layer to complex backend processes. I am a Full Stack Developer helping clients who need solid React developer work paired with strong Node.js backends.
I have experience delivering 40+ client projects for about 10 diverse clients, making me a safe choice as your full stack developer. My skills span the entire scope of Full-Stack Development, supporting both Web Application and pure Web Design needs. I am a highly capable web developer who manages multiple tech stacks effectively. For instance, I have delivered several key features like:
• Migrating complex Django monoliths to microservices, improving maintenance for 15+ modules in 5 years with the Senior Django Developer role.
• Building real-time data pipelines using technologies like Celery and RabbitMQ that handled millions of daily events across my 8+ year experience as a full stack developer
• Developing secure RESTful APIs using Node.js/Express and TypeScript for SaaS backends, serving over 30 unique API Integrations to different clients.
I work with React developer patterns constantly to make sure the user sees something fast and clean. As a Full Stack Developer, I am comfortable acting as a react developer when needed, supporting the frontend build using modern JavaScript and CSS principles. Another example of my capabilities:
- Implementing advanced AI RAG systems, connecting LLM APIs via LangChain for up to 5 distinct knowledge sources, backed by professional backend work from the last 1 year.
I am committed to being a top-tier web developer and full stack developer. As a Full Stack Developer, I understand that every detail counts, from the Bootstrap usage on the frontend to the query tuning in MySQL on the backend. A good react developer must know how to write clean HTML5 and effective JavaScript for maximum Web Design impact. Many times, clients wrongly assume they need a simple wordpress developer when what they really need is sophisticated full stack development using React or Angular frameworks. I ensure that no one needs a basic wordpress developer if they are ready for real web applications built with Python/Django or Node.js. The best Full Stack Developer and SQL Developer helps you avoid the mistakes of a low-skilled wordpress developer at any cost.
I am also skilled in advanced backend logic, acting as a dedicated python developer when the task requires it. I ensure that my work exceeds what a generalist full stack developer might offer by mastering core Software Architecture & Design principles. For example, building complex SQL stored procedures as SQL Developer and serverless components using Python Lambda functions over 4 years allowed me to deliver reliable systems for critical financial processes.
❌ I'm not a wordpress developer, please don't invite me to wordpress projects
❌ I'm not a mobile app developer, please don't invite me to mobile app projects
I bring 12+ years of overall experience as a full stack developer, building reliable Web Applications using technologies like JavaScript and React. My dedication as a Full Stack Developer and SQL Developer means you get a single point of contact that knows how to write good CSS, HTML5, use Django, and manage Node.js environments equally well. I am the web developer who makes it run smoothly in production environment every time.
