I'm Rolandas Šimkus
And I'm a Senior Software Engineer based in Lithuania
I specialize in Rest API development, scripts that simplify day to day work and much more.
My passion is to design new services, implement and ship them to production with the highest quality. I enjoy working on various automation scripts that can improve clients daily performance when it doesn't need to do tedious things repeatedly.
I design and develop Rest APIs, Microservices and other tools for customers of all sizes.
High quality is essential for any Service or Tool that I work on, so I make sure that all deliverable is covered with a proper unittest coverage, E2E tests and if necessary performance / load tests.
Creating scripts for various purposes: schedules, CI/CD pipelines, data manipulation and much more.
Implementing new Services and working on already existing ones. Each implementation is backed with tests.
Design & Architecture
Designing and preparing Architecture for new and existing Services.
Implementing improvements and fixing issues.
Consulting clients on various topics: design, architecture, tooling, services and more.
Providing mentoring services for other developers and clients.
Making Things With Passion.
Each project requires different tooling / skills. I focus on back-end with tools that provide best time / cost efficiency.
Here are some main tools from programming language to cloud services that I work constantly.
