What I'm looking for

I’m looking to join a fast-paced, scrum-based team where I can own RESTful API and full-stack development, improve system reliability and performance, and use testing and CI/CD to deliver measurable outcomes—ideally in regulated SaaS environments.

I’m a Senior Software Engineer with about 12 years of experience, focused on building scalable backend services and RESTful APIs while integrating high-quality frontend components. I’ve worked in scrum-regulated environments, including a SaaS platform serving 1,100 pharmaceutical and biotech companies, where I bring a strong ownership mentality and meticulous attention to code quality.

I’ve delivered measurable outcomes, including a RESTful API that improved data retrieval speed by 30%, and a legacy-to-microservices migration that reduced system downtime by 40% while improving scalability. I also developed testing frameworks with JUnit and Mockito to reduce bug rates by 20%, implemented CI/CD pipelines with Jenkins to cut release times by 50%, and created monitoring/logging solutions that reduced response times by 50%—all while mentoring developers and collaborating cross-functionally.
