  (Lambda, EventBridge, Step Functions) that improve performance and resilience.
• Translating business and functional requirements into practical, well-architected solutions using
  TypeScript, or Python,
  and modern development frameworks.
• Guiding engineering teams through architectural decisions, providing hands-on support, design reviews, and technical mentoring.
• Collaborating with product and delivery teams to balance speed, stability, and scalability in every solution.

• Your hands-on experience applying Hexagonal Architecture, Event-Driven Architecture, and Domain-Driven Design to build scalable, maintainable systems.
• Your technical capability across TypeScript, , and modern programming frameworks, with the ability to design and review high-quality code.
