Vinoth Kumar K.

I'm a full time freelancer and I specialize in automation development (& general backend dev) with Python, NodeJS and occasional Shell Scripting.
I also do front-end web development - you can checkout my other Specialized profile for this.

I have good experience in building backend systems, fully automated workflows, etc. - local & distributed/on-the-cloud with AWS/GCP/Azure.

14+ years

I always start with proper tasks & estimates and will be consistent with regular updates. This way there will be no surprises in cost/time and you'll be up-to-date with the progress without you having to chase around the freelancer.

When delivering my code, I’ll make sure that it is well designed, professionally written to the highest quality & efficiency with solid, re-usable, following OOPS concepts, proper commenting & documenting.
Future developers (if any are hired after me for maintenance/updates) can go through the code and update/refactor with ease - I know how it feels as a developer to read bad code and attempt to do anything on top of it.
