I’m a Senior Android Developer with over 10 years of experience building mobile apps using Kotlin and Java. Over time, I’ve worked on different types of projects, from enterprise tools to consumer apps, and I really enjoy turning ideas into reliable, easy-to-use products. I actually started my career in backend development and QA, which helped me build a strong foundation in how systems work end-to-end. Eventually, I found my focus in Android development, and that’s where I’ve spent most of my career. In my current role, I built an app used by field technicians to manage and submit meter checklists, taking care of everything from architecture to implementation. In a previous role, I worked on a social media app where I had ownership over key features, worked closely with the product team, and also helped onboard and mentor other developers. Earlier on, I had the chance to work on a variety of apps across different industries like education, logistics, and media. One highlight was helping fix a critical issue in an audiobook app that improved how users downloaded content. I’ve also built many apps from scratch earlier in my career, which gave me a lot of hands-on experience. What really sets me apart is that I don’t just focus on coding — I like to understand the bigger picture, make thoughtful technical decisions, and build things that are maintainable long-term. I’m also always looking for ways to improve how I work, whether that’s learning new tools or finding smarter ways to deliver better results.
