Leon Olszewski’s Expertise I was born to make software - I just love it! I’m a diverse software professional who’s always ready to try new things. I’ve spent years building and rearchitecting microservice based backends. That includes the databases, caches, message brokers, service interfaces, load balancers, API gateways, etc. I've designed and built out entire iOS and Android frontends. I’ve built web applications using modern frameworks like Angular and I’ve supported legacy ASP.NET web applications as well. I've even written apps to interact with programmable logic controllers in industrial settings. I'm particularly well learned on the topic of authentication standards such as OAuth 2.0, OIDC and SAML, having done a number of such integrations as service provider and identity provider alike. Over the years I've learned that delivering value for the business isn't just about writing great code - It's about building the right thing, getting it into customers' hands quickly and collecting returns (it is a business after all). That is to say the process by which you produce software goes hand in hand with the design of the software itself. This is where I believe Agile and DevOps philosophies really shine, and I've been a strong advocate of both for a long time. I'm well acquainted with ideas like continuous integration and continuous delivery and their enabling tools. For me it's not about following "the right process" in a one-size-fits-all way; it's about matching the solution to the problem. I'm looking for an opportunity to apply my experience and energy. I love building great solutions with great people. Check out my blog at https://www.codecomplete.tech
