About
Hi there! I’m a software consultant with 10+ years of experience in full-stack development, including 5 years with Angular and Node.js, 4 years with Java/Spring Boot, and 4 years with React. I’ve contributed to startups, mid-market companies, and global enterprises across frontend, backend, and cloud technologies. I love turning complex problems into scalable solutions and collaborating with cross-functional teams to deliver value.
Beyond writing clean code, I mentor teams, drive architecture decisions, and help clients articulate goals and deliverables. I enjoy optimizing CI/CD workflows, improving performance, and guiding stakeholders through technical trade-offs to achieve business outcomes.
