About Jon Sajdak

Experienced software engineer & architect, with extensive leadership experience. Deep experience as software engineer in front end web (currently React.JS), along with almost a decade working with mobile iOS development (Obj-C + Swift). Technical lead in web and mobile platforms designing frameworks, APIs, platforms and all aspects of app infrastructure. Extensive R&D work developing solutions to complex problems. High accountability in all aspects of software development, independently, leading teams or part of a high-end team. Have a long history working with various teams across startups of all sizes, from founding engineer, seed+Series A/B funding, and buildups to medium size teams. Throughout my career I\'ve shifted in and out of different leadership roles and platforms. I\'ve worked in web technology both on server and client sides. I\'ve managed Unix/Linux server admin, managed web servers (Sun/Solaris, Apache, IIS- mostly pre-cloud though), deployments and managed engineers and small teams relating to such. I\'ve always been hands on as well, and thus able to understand what a team\'s engineers accomplish, even if that means distributing the work for efficiency. Primary Development Environments: Javascript, React.JS, typescript; Swift/Objective-C Other technologies: GraphQL, Restful APIs, SQL, CI, platform setups (Azure, Architecutre as code) Previous Languages: PHP, Java, C#, Perl, C++, C, LISP, shell In addition to experience, see projects section below for detailed list of personal side projects over time.
