Flutter developer, building mobile apps and the shared code inside them.
Five years building mobile apps at Sutherland Global Services, SuneraTech and Ezshipp — plus two free code packages I published that other developers now use inside their own apps.
Context
I’m Ankeshwarapu Hitesh, a Flutter developer in Hyderabad. Five years across an enterprise services firm, a product company and a logistics startup — migrating legacy Android and Xamarin apps to Flutter, then maintaining the low-level packages those apps ended up needing.
Flutter and Dart apps for big companies, organised so they stay easy to change as they grow. One shared codebase serves many different clients, each with its own way of working.
I have published two packages on pub.dev, the official site where Flutter developers share code. One lets an app talk to a Microsoft SQL Server database on five platforms; the other stores an app's logs in far less space. Both are downloaded and used every month.
Claude Code, Codex, Devin and Windsurf wired into daily engineering work — with prompt and context engineering used to hold enterprise code quality while compressing the schedule.
Proof
Every number here comes from work that shipped. The last column says exactly where each one came from, so none of it has to be taken on trust.
| Number | What it is | Where it comes from |
|---|---|---|
| 160/160 | package quality score | A full score for ctls_logging on pub.dev — the official site where Flutter developers publish and download shared code. |
| 140/140 | package quality score | A full score for mssql_connection on pub.dev. |
| 1.7k+ | downloads every month | Other developers install mssql_connection and use it inside their own apps. |
| 66% | less time to deliver | A project planned for three months, finished in one at Sutherland, using AI coding assistants. |
| 5 | platforms from one codebase | mssql_connection runs on Windows, Android, iOS, macOS and Linux without a separate version for each. |
| 15+ | screens rebuilt | Older Android and Xamarin screens moved over to Flutter at SuneraTech. |
| 30% | faster app | Measured across those rebuilt screens, before and after. |
| 40% | quicker to open | Alongside 25% less memory used, after tuning the app's performance. |
| 45% | fewer crashes | The Ezshipp delivery app, after I fixed more than ten major bugs. |
| 50k | rows/sec bulk insert | The bulk-save path (BCP) in mssql_connection, writing records in batches. |
| 80× | fewer trips to the database | Sending records grouped together instead of one at a time — far less waiting on the network. |
| <1µs | per log write | Under a millionth of a second — ctls_logging writes straight into memory instead of to a file. |
| 70%+ | less storage used by logs | Compression built into ctls_logging, so apps can keep far more history. |
Selected work
Open any row to see what the work actually involved. Two of these are free packages anyone can download and use today.
A system that tracks products from the factory to the shop shelf, across phone, desktop, web and cloud. I build the mobile side of it in Flutter.
Track record
A large services company, a product company and an early-stage delivery startup. In every one of them, the job started by moving an existing app over to Flutter.

Hiring for Flutter, want to ask about one of my packages, or curious how a three-month project shipped in one — any of those is a good reason to write.
