Lead engineer with 15+ years building and shipping web products, evolving from web-focused development into product-driven systems design.

Specialized in bridging product intent with scalable technical execution—designing architectures, developer workflows, and tooling that reduce iteration time and improve delivery reliability.

Along the years, had to hone certain skills in various domains:

• Translating product requirements into scalable systems
• Sense of ownership, clarity, and a focus on delivering impactful results
• Cross-functional collaboration and conflict resolution
• Stakeholder presentations and communication
• Technical leadership, mentorship and enforcing standards
• Frontend, Backend and Infrastructure architecture
• API design and integration
• Monitoring, Performance optimization and scalability
• Processes automation (PRs, CI/CD, releases, secret management)

Recently focused on AI-augmented workflows, internal tooling, and system-level thinking to increase team leverage and product velocity.
