Testimonials

"Mikon kanssa on helppo työskennellä. Hän on omistautunut työlleen ja on valmis venymään tarvittaessa, koska hänellä on aina myös asiakkaan loppuasiakas kirkkaana mielessä. Ehdottomana plussana karttunut ymmärrys energia-alasta ja siihen liittyvistä teknisistä yksityiskohdista ja markkinasta. Pitkän linjan kokemus näkyy rauhallisena ja varmana otteena työssään tehokkuudesta tinkimättä."
--- Tiina Salmi, Service Manager at Elenia (customer, 2024)
"Mikko is one of the most experienced developers in HSL mobile app-team. He easily understands the business logic and puts that into code. He is easy to work with, talented in his field and very reliable. He finds solutions even under pressure and with very little sleep – like after a night when HSL converted into new zones. I highly recommed Mikko as a senior level developer."
--- Satu Rönnqvist, Product Manager at HSL (customer, 2019)
"In a desperate need for talented developer that documents both his code and the findings, people (non-devs) recommended Mikko to me. I decided to reach out to Mikko, and he jumped in instantly. Fast forward to results.. I got easy to comprehend documentation, clean code and debriefing. I am very pleased and can easily recommend Mikko for senior level dev tasks."
--- Sami Keskinen, CEO at StoneCrew Oy (customer, 2017)
"It was an honor to work with Mikko at eTasku Solutions Oy. He has the right attitude what comes to web development. He's eager to learn new technologies and loves to keep himself up to date with latest tricks."
--- Toni Leppänen, CTO at eTasku Solutions Oy (employer, 2017)
