I'm Tonko,
Full-Stack Software Developer
Full-Stack Software Developer
I have more than 10 years of web development experience working with enterprise solutions on premise and cloud for a wide variety of industries. Before becoming a developer, I did system administration which provided me with invaluable experience to also do the Ops part while doing the Dev part. I also hold a couple of dozen Microsoft Certifications to prove it.
Green field, brown field, rewrite or legacy project? I've did them all. I like solving problems and I'm interested in all of them! I have worked solo and in teams as a developer, mentored junior and mid-level developers, led projects as a team lead, and analyzed and advised on software development process.
I'm best skilled in Blazor, Vue, React, Svelte, .Net Core, SQL and Docker. During rewrite and legacy projects I've also been exposed to AngularJS, NodeJS, pretty much all ASP.Net technologies, and of course WinForms and WPF. I also used Selenium to write integration tests and wrote some automation scripts using Playwright. I would love to do more work like that.
Once the Docker craze hit, I decided to prefer developing apps to run in a cloud-native OCI compliant containers. I loved it so much that I even write them in containers! After all, what better way to make sure there are no surprises after deployment. While transitioning to cross platform development, I've set up a local Linux server which is now years later used to self-host a whole slew of containers that provide services to me and my extended family. For reliability, I've also had to deploy some of those containers to the cloud and I must say how amazed I was when I realized containers are cloud agnostic and I could easily switch from one cloud provider to another.
