I also optimized queries and orchestration to make API responses approximately 5× faster. At Kuelap.inc, I refactored application code, database queries, and backend orchestration, improving API response times by 10–15×. I also helped revamp frontend components for greater reusability. At onebrick.io, I designed and implemented data-integration APIs, launched a Data API MVP in six months, and led the upgrade from a synchronous version 1 to an asynchronous version 2. I supported client onboarding while building scalable backend services. I've worked across Java, Kotlin, .NET, PHP, PostgreSQL, MySQL, React, Angular, and API development. I also bring Scrum Master experience facilitating Agile ceremonies and working with product owners to prioritize requirements. ``` ## Experience ### Senior Software Engineer (current) SoftwareSeni.
