About

Results-driven Software Development Engineer with 5+ years of experience architecting scalable systems that solve complex technical challenges. I transform business requirements into elegant technical solutions that deliver measurable impact. Technical Expertise: Backend Development: Java, Python, Spring, Hibernate, Django, JUnit, Mockito Architecture: Microservices, Event-driven design, System scalability Infrastructure: AWS cloud ecosystem, CI/CD pipelines At Bizongo, my current role as Software Engineer 2 has allowed me to showcase my abilities in designing and implementing high-performance systems using TDD methodologies. I've engineered RESTful APIs that achieved remarkable efficiency gains, reducing response times by 95% and reaching a P99 latency of just 300ms. My work with AWS Lambda for HubSpot integration resulted in a 90% reduction in API response time. I led the replacement of a legacy system through implementation of new microservices and database normalization, which not only improved system performance and maintainability but also generated $36K in cost savings. This demonstrates my ability to balance technical requirements with business objectives to deliver tangible value. During my time at Spoonshot, I architected and delivered the first version of the "Genie" operations platform using React, Django, and MySQL, while also optimizing core RESTful APIs to reduce the response time by 70%. This resulted in a 30% reduction in user-reported latency issues, highlighting my full-stack capabilities and user-focused approach. At Zenoti, I led end-to-end development of customer onboarding and payment processor setup, including a dispute management subsystem that enhanced visibility and minimized communication overhead. I also demonstrated exceptional operational efficiency by resolving over 100 monthly customer and internal queries with a 92% first-contact resolution rate. Beyond technical accomplishments, I've proven my leadership capabilities by mentored team of 7 through structured weekly sessions. By providing guidance on best practices and code quality, I helped reduce code review iterations by 30% and increase team velocity by 25% within 6 months, showing my commitment to team growth and development. Passionate about continuous learning, performance optimization, and creating resilient distributed systems that deliver measurable business value. Committed to engineering excellence and collaborative problem-solving to tackle complex technical challenges.
