Joonas Sirén’s Expertise I've been a developer since 2009, first starting out in frontend and from there quickly expanding my skillset and shifting towards more backend, or actually fullstack development. Gradually over time, working in many levels and roles, I progressed into the role of a technical architect, which I've been doing from 2013 onwards. During my career I've held the positions like frontend developer, lead developer, lead architect, solution architect and the likes. I've seen and experienced many of the horror stories that are quite common in software development, from the no scope yet fixed price projects, to the horrid client experiences, and yet, all of the projects I've participated in, I've seen through and triumphed at the end. And those turnovers are the ones that have taught me the most about what makes the difference between the success stories, and the ones that fail. My biggest strength is, that I have the ability to convince clients, and educate them about the right solution for their specific problem, and most importantly‚ gain their trust and turn them over to our side, whilst keeping them happy, and yet always striving to do the right, the ethical things, from the projects perspective, in order to hit the mark and deliver the best solution possible for all parties involved. To date, in all of my projects, I've been working in different custom development projects, utilising mostly open source technologies, and a few others of the likes of: - React - AWS - Node.js - Angular.js - Google Guice - Postgres / EnterpriseDB - Flyway - Spring Boot - JSF (Icefaces) - Java - Hibernate - Spring Frameworks - SQL Server - Heroku
