Showcase project

Monthly App
Budget and savings tracking app
I wanted to create a budget tracker for myself, friends and family. This also serves as a playground to demonstrate my skill in building a real-world CRUD app where product and infrastructure is setup from ground up.
Client side has scalable React/Apollo architecture with MUI library and Webpack. GraphQL API is built with Node.js and Prisma ORM.
How I work
Effective and transparent communication
Many developers fall into trap of just writing code. But what they often forget is asking the right questions early on and solving a problem with prompt communication. Throughout my experience I learned how to shave off weeks and even months of unnecessary work with transparent and effective communication.
Pragmatic with business goals in mind
My goal is to help you build a successful business, and every online business needs to move fast while ensuring code quality. I can quickly grok the perfect balance and develop your product with speed and stability.
I won't waste your time
I am a self-managed contributor who can mold into your processes very quickly, so I won't need much hand holding. I know when to ask for permission and when to make decisions independently.
Flexible and risk free engagement
Hiring new talent is a great challenge and even bigger risk. I prefer to have happy clients who choose to work with me on a daily basis. In order to do that I prefer signing flexible contracts which you can terminate at any time. Not that you will need to🙂
