Temporary support - Fix the Bugs
Devansh is a highly skilled Full Stack Developer who did an excellent job working on our SQL Server meal-planning system and related integrations. He quickly understood a very large and complex stored procedure architecture and was able to work confidently across backend logic, APIs, and supporting application workflows.
He helped identify and resolve issues related to recipe rotation, blacklist consistency, and overall workflow stability while maintaining clean and reliable code. What stood out most was his proactive approach and problem-solving mindset.

Devansh is professional, communicative, and easy to work with throughout the engagement. His combination of strong backend, database, and full stack development skills made a significant impact, and I would confidently recommend him to anyone looking for a dependable Full Stack Developer.
