Online-tilassa Offline-tilassa
Hi, my name is Sergio and I work both as agile lead developer and project manager so I offer services both as individual or as small team/company as I can quickly build a team of developers based on your needs. You will have contact directly with me and not with a third person. I have 5+ years experience as lead developer in Angular, MEAN (MongoDB, Express, Angular, Node.JS) and related technologies (Universal, Material, NativeScript, Cordova...), 10+ in LAMP (Linux, Apache, MySQL, PHP) projects and 15+ in general development (Java, JavaScript, Bash...). I’m focused on top quality and standards. All the code I work in is thoroughly reviewed and always follows the best practices. I also have experience in improving the quality of low qualified teams over time. I can show real and verifiable samples of my work privately. I keep a good relationship with all my previous and current customers so I can provide any references you need.
