Paweł Dolega

Software engineer / entrepreneur. New technologies & interesting ventures. Worked in international corporations, small local software houses (two of which I co-founded) . These days my weapon of choice is mostly Lightbend stack (Scala / Akka / Play / Spark) though I am trying to remain flexible and not be too orthodox.

Far more important than actual technology – I am really passionate about technological challenges and problems that technology is trying to solve. I like to work on things that matter.

Worked as a software engineer, development lead and technical manager. Delivered projects both in government and private sector, both in Poland and abroad. All the projects delivered successfully, avoiding government contract fines or customer dissatisfaction (most, if not all, customers were returning ones). Had to fight teeth and nails from time to time to make it happen because of constrained staffing or extreme deadlines.

I worked with large-scale, highly available systems serving millions of clients, been involved in coordinating efforts of teams scattered around the world with crazy timezone differences and spent lots of time in modern virtualization / cloud computing initiatives / projects. Worked mostly with Unices (as plain Linux, Solaris, HP/UX, AIX and i5).

Worked with dozens of DB engines (relational, graph or document based), frameworks and technologies. My key skill is the ability to learn and *adapt* – and doing it rapidly.

Infrequent conference speaker and open source contributor.
