Vladimir Vorobiev

I am a Senior / Lead Full-Stack Developer with over 20 years of experience designing and delivering scalable enterprise applications, SaaS platforms, and cloud-based systems across .NET and modern JavaScript ecosystems.

My background combines deep hands-on engineering expertise with technical leadership across frontend, backend, API, and cloud architecture. I specialize in React.js, TypeScript, Node.js, NestJS, and .NET technologies, with extensive experience building high-performance applications, modernizing legacy enterprise platforms, and designing scalable microservice-based systems.

Throughout my career, I have worked across industries including EHSQ/ESG software, business intelligence, security operations, merchandising, real estate, and enterprise workflow automation. I have led modernization initiatives, implemented secure API architectures, improved platform observability, reduced technical debt, and delivered systems focused on long-term maintainability and operational reliability.

In recent roles, I architected and developed modern React applications using Redux Toolkit, TypeScript, and Material-UI while building scalable backend services with Node.js, NestJS, MongoDB, and Azure cloud technologies. I also introduced structured logging, monitoring workflows, automated testing strategies, and performance optimization initiatives that improved both engineering productivity and system stability.

Beyond development, I work closely with product managers, stakeholders, and engineering teams to translate complex business requirements into practical technical solutions. I have experience mentoring developers, leading code reviews, and supporting engineering best practices within Agile delivery environments.

I am particularly interested in opportunities where I can contribute to system architecture, technical leadership, platform scalability, and modern application development while continuing to build high-quality software that delivers measurable business value.

Thank you for your consideration. I would welcome the opportunity to discuss how my background and experience can contribute to your team.
