About Kevin

With 13 years of experience in software engineering, I design and develop robust and scalable web platforms, working across the entire stack. My background in various sectors, including public service, finance, cybersecurity, healthcare, and retail, has provided me with a comprehensive understanding of product and technical challenges.

Expertise
  • Technical Architecture: Designing performant, modular, and scalable systems, adapted to product challenges and team organization.
  • Full-Stack Development: Mastery of major frontend frameworks (React, Vue, Solid, Angular) and modern backend environments (Node.js, Spring, Kotlin), with a strong focus on code quality and developer experience.
  • Stack Modernization: Refactoring and migrating existing systems to improve maintainability, performance, and team agility.
  • Product-Tech Collaboration: Experienced in working within multidisciplinary teams, mentoring developers, and maturing engineering practices.

Engineering Values
  • Software Quality: Clean, structured, easily testable, and sustainable code.
  • Delivery Orientation: Pragmatic and iterative approach focused on continuous delivery of value.
  • Adaptability: Ability to quickly grasp new business or technological contexts.

My experience as a tech lead allows me to manage complex projects, align technical choices with business objectives, and contribute to the growth of both teams and systems.
