Rupak Basu
Freelancer
Python/Flask development | AWS support
Welcome to my website. I am a software developer and IT professional from Kolkata, India, with hands-on experience of 15+ years.
I provide freelance service in Python/Flask based development of cloud-native Microservices/APIs, and also the backend of monolithic SaaS/web applications; both exclusively targeted at AWS cloud for deployment. I also provide freelance hands-on support in AWS infrastructure deployment, management, and troubleshooting. The core technology areas I can work in are listed here.
If your business/organization is planning to convert one or more parts of your existing monolithic SaaS/web application to independent, scalable, highly available, high-performance Microservices, or if you are thinking of building a robust, state-of-the-art, monolithic SaaS/web application, then you may hire my freelance development service in those endeavours.
You may also hire my freelance service if you need hands-on technical support in your AWS infrastructure deployment and troubleshooting challenges, pertaining to any of the areas listed here.
Demos of work
If you want to check out live examples of my work, this website hosts several self-service demos. These demos have been developed by me. They are deployed & managed on my own AWS infrastructure, using most of the components listed in the technology stack here. Feel free to sign up and try out these demos.
Technology stack/Skill set
(My work pertains to Linux platform only, and not any other OS platform)

Demos of work: FAQ
An account may also be deactivated by us at any time without notice if unusually high or abusive activities are observed in that account.
- While the demos are free to try out, you will have to use your own service providers' (e.g. AWS) API/Access keys in the demos. That may incur charges in your service providers' accounts accordingly.
- It is strongly recommended that you create new, temporary API/Access keys in your service providers' accounts for using in the demos, and delete those keys immediately after checking out the demos.
- Upon deactivation of your account, all demo data created by you on this website (e.g. API keys, conversations, messages, assistants, documents, Q&A etc.) will be deleted. However, your sign-up data (name, email, organization, website etc.) will be retained with us in order to prevent potential abuse of the demos by malicious users.
- The demos here are not real, feature-rich, professional SaaS/web applications or Microservices. They are just application fragments, demonstrating examples of my work, meant only for checking out. If you are interested in hiring my freelance service for building real, professional SaaS/web apps or Microservices, you may initiate a business enquiry.
- Accuracy of output in the demos is solely dependent on the output of the underlying third-party APIs and AI models integrated (e.g. AWS Bedrock).
- You should provide authentic information about yourself in all the fields in the Sign-up form. If we suspect that you have provided false/dummy/placeholder information, your signed up account will be deactivated without notice.
- You should not misuse or abuse the demos on this website in any manner. If you do, your signed up account will be deactivated without notice.
- The demos are provided "as is" without warranties of any kind, express or implied. Availability, accuracy, security, and reliability of the demos are not guaranteed.
