Full-stack Developer
Match Score — ruby on rails developer
N. has over 12 years of continuous, recent Ruby on Rails experience across multiple roles up to 2024, including full-stack development with PostgreSQL, React, AWS, and integrations like Stripe, directly matching the Ruby on Rails developer role. Strongest signals include leading end-to-end development on production apps (e.g., map app for businesses, spare parts tracker), performance optimizations, and startup founding with investment, demonstrating ownership and impact. Excellent education from a top Serbian CS program, clear CV structure, and no stale skills—all RoR experience is current and hands-on. Minor concerns are part-time availability (may not suit full-time roles) and Serbia location (potential timezone issues for non-remote jobs, though JD unspecified), plus some early non-RoR experience that's irrelevant. Overall, exceptional fit with minimal risks.

Work Experience

- Worked on several projects, some of them pilot projects. The biggest were built for a thermal coal power station in Serbia (TE Kostolac). Built one app using Ruby on Rails, PostgreSQL as a database, and React as a front-end framework. The application shows a map of various businesses in Belgrade and a user can filter them, click on a pin on the map, and see all sorts of information. Created another app using Ruby on Rails and Oracle as a database. It keeps track of more than 7,000 types of spare parts for all kinds of vehicles and keeps track of which vehicle can use which part. Users are able to edit parts and filter them. Wrote procedures in Oracle PL/SQL for one application to calculate the average fuel consumption for excavators, bulldozers, and other vehicles on the open pit. Led the entire development process, including talking to the end customers, building functionalities, testing, deployment, and more. Gained experience in handling a demanding freelance schedule and workload.
