Convert APNG Files to iMessage Sticker Pack
I highly recommend Arjun. He was very patient while we worked through some changes to the project on our end and he was always available for support. His skill in helping us get our Sticker Pack App on the Apple App Store was extremely helpful. He knows what he's doing. He's communicative, patient, kind and ready to work. It's hard to find people like this. Would definitely recommend Arjun to anyone.

iOS SDK Prototype Development (Swift) – License-Based Dynamic WebView System
I hired Arjun Gautami based on his strong profile and 100% success rate, and initially had high expectations for the project. However, during the course of development, communication and collaboration became challenging once detailed code review feedback was provided.
There appeared to be reluctance in addressing improvement requests, and it was often difficult to schedule calls to discuss technical concerns or clarify implementation details. It is possible that the project scope or complexity was underestimated during the bidding stage, which may have contributed to the difficulties encountered during execution.
After approximately three months of engagement, the delivered codebase still requires significant rework on our side, and a considerable amount of time was spent on follow-ups and coordination.
For relatively straightforward or standard projects, Arjun may still be a suitable choice. However, for projects involving more complex, custom, or evolving requirements, clients may want to assess technical alignment and communication expectations carefully before proceeding.
I sincerely wish Arjun the very best in his career and hope he continues to grow his technical and professional skills with experience.
