Technical Leader, Solutions Engineer, Mentor.
mikeportnov.com · Telegram · LinkedIn · Blog
Full-stack engineer and tech lead, in IT since 2017. I've worked across the whole product: backend and architecture, web frontend, mobile apps, infrastructure and observability. Domains: payments and lending, cloud security, edtech.
I've grown from engineer to head of engineering, led a team of 10 and taken products from an empty repo to production.
Since 2019 I also teach: built the Kotlin Backend track at JetBrains Academy, taught Android at Samsung IT School, coordinated bachelor's and master's programs at MEPhI. Now I run Punto Cero, a 10-week group program on goal setting and personal effectiveness, and mentor engineers 1:1.
