Tejas Nasre aka Builder
I'm a full stack engineer at heart, building mobile and web products almost 90% of the time. I focus on writing clean, scalable code with strong attention to product experience and performance.
Product-focused developer who takes ownership and enjoys building scalable applications from end to end. Looking for opportunities to work on large-scale mobile products within a team that values growth, strong peer mindset, and sustainable work culture.
