I am a highly experienced and versatile full-stack developer with demonstrated proficiency in back-end optimization. Having worked with a wide variety of different technologies, I am able to easily find the best solution for complex problems and projects without bias. Furthermore, I have a sound understanding of technologies from the entire development stack. I specialize in software engineering, analysis, design, testing, configuration management, re-engineering, UML, and process development. I optimize bottlenecks through concurrency/caching and by finding the best possible tools. I am passionate about developing clean, fast, and organized applications that make the best use of today’s top existing and emerging technologies.
