What I'm looking for

I’m looking to build scalable web/mobile products end-to-end—shipping APIs, databases, and performance improvements—while using analytics to improve user experience and retention, working in an Agile, collaborative team.

I’m a Software Developer(Web&Mobile) with 5+ years of experience building and maintaining scalable applications. I’m proficient in JavaScript, Python, Vue.js, Quasar, Django, and Firebase, with strong full-stack development, mobile app delivery, and cloud-based systems experience.

I focus on end-to-end product delivery—designing and implementing APIs, database models, and performance optimizations, then using analytics to improve user experience and retention. I’ve built user tracking systems to monitor engagement, behaviour, and goal completion and improved products through debugging and data-driven enhancements.

Beyond development, I bring QA and delivery experience from Quality Assurance work and Agile task management, plus leadership from founding and leading operations for digital platforms. I enjoy collaborating across teams to ship reliable features and continuously improve system stability and responsiveness.
