Rostyslav Ross

I’m a Full-Stack / Backend Engineer with 12+ years of experience building production-grade web applications, with a strong focus on backend systems, distributed architectures, and scalable APIs. I specialize in delivering reliable, long-term production systems, not just working demos.

Throughout my career, spanning fast-paced startups to structured corporate environments, I have consistently driven features from concept to release with complete ownership. I thrive in environments with mature engineering processes, working closely with cross-functional teams within Agile/Scrum frameworks, establishing strict testing patterns, and conducting rigorous code reviews to ensure maintainability.

I leverage modern AI tooling to accelerate development velocity, but critical engineering decisions remain human-driven.

🔹 My workflow focuses on: Designing clean, scalable architecture before writing code | Setting up reliable processes (CI/CD, comprehensive testing, strict code review standards) | Reviewing AI-assisted code for correctness, security, and performance bottlenecks | Challenging generated solutions instead of blindly accepting them | Ensuring systems are maintainable, predictable, and production-ready.

🔹 Key areas of expertise: Backend systems & architecture (Python, Node.js) | API design & complex third-party integrations (Payments, SaaS) | Scalable data processing pipelines (Celery, RabbitMQ) | Database architecture & query optimization (PostgreSQL, MySQL) | Frontend development (React, TypeScript).

🔹 Selected engineering highlights: Built and delivered 40+ production-grade web projects | Led the migration of monolithic Django systems into modular, service-based architectures | Designed and optimized data pipelines handling high-volume event processing | Built secure payment layers, multi-tier caching (Redis), and AI-powered production workflows (RAG, LangChain).

⚙️ Tech stack: Python, Django, FastAPI, Node.js, TypeScript, React, PostgreSQL, MySQL, Redis, RabbitMQ, Celery, REST APIs, AWS, Docker, Git, CI/CD pipelines.
