Work Experience
Senior Full-stack Developer
Silversheet
- Helped to develop a medical credentialing platform called Silversheet. I worked both on the front and back end.
- Created a bunch of proof of concepts to check the viability of an idea. For example, I researched and implemented SSO MVP.
- Migrated some functionality to microservices (Amazon Lambda).
Full-stack Developer
Social Media Link
- Implemented data sync to various CRMs as a microservice, which saved the client's clients a lot of time: they no longer need to manually synchronize data between Social Media Link and their favorite CRM this way.
- Collaborated on the migration of AngularJS to a Vue single-page application.
- Worked as a back-end developer to improve general platform performance.
Senior Rails Developer
Spreemo Health
- Performed a complete migration from PHP to Ruby on Rails, making the development stack more modern and flexible.
- Developed a data sync service between QuickBooks and Spreemo, which dramatically simplified accounting work for the company.
- Worked on data migration after a codebase change, ensuring no precious medical data was lost.
