My journey reflects a passion for crafting innovative digital solutions, backed by successful funding rounds and impactful results. Passionate about Kotlin, Jetpack Compose, and building seamless user experiences, I’ve also worked on backend integrations using Node.js and Google Sheets APIs, processing 100k+ entries/month.
