NextJS/NestJS Developer (Tanstack Query, Supabase, React Hook Form, and Chakra-UI) Working with Sachin has been great. He's able to take complex requests and put together all the pieces needed to make them real in our codebase while matching our coding standards. His verbal and written communication skills are solid - I really appreciate the detailed daily reports that he gives. I'm looking forward to working with him again.

Clients usually work with me because they want someone who:
🔹 communicates clearly and proactively

🔹 thinks beyond features and focuses on business impact
🔹 builds software that remains maintainable as the product grows
