About Me

Ersin Er

I’m Ersin Er, a Software Architect focusing on the Cloud. I’ve been building distributed systems and leading engineering teams. LBNL, I’m an AWS pro.

Nowadays I’m an IoT Specialist. I’m busy with architecting IoT systems end to end; from embedded software to mobile applications, from cloud software to overall communication and integration subsystems. Expectedly, Security is one of the foremost concerns for my work.

Since early 2016, I’ve been working for Arcelik Group (a global household appliances manufacturer with headquarters in Turkey), in the R&D Office in Ankara, Turkey. I’m leading the Software and Systems Architecture, DevOps and Agile Development related aspects of the IoT effort therein with a particular focus on Cloud Computing.

You can find more information about me below and via my  social  profiles.


I’ve have been working as a Software & Solutions Architect, and as a Software & Systems Engineer as well, experienced in Cloud Computing, Distributed Systems, Concurrency, NoSQL & Big Data Technologies and Backend/Systems/Infrastructure Programming in Java and Administering Linux Systems.

I’ve BS (2003) and MSc (2006) degrees in Computer Science and I’m a lazy PhD candidate (which may even not be the case any longer).

As a Tech Lead I’ve managed and supported several Agile Projects and Teams.

In the past:

Worked as a Software & Solutions Architect at Metasolid, a Cloud Computing and Big Data startup, from early 2014 until late 2015.

Worked as a Software Architect and Technical Leader at Peak Games between late 2010 and late 2013.

I’ve been an ASF Committer and PMC Member of the Apache Directory Project since early 2005.

Worked as a Teaching Assistant (and System Administrator) at Hacettepe University, Dept. of Computer Sci. and Eng. for 7.5 years.

In general:

I’m strongly inclined to turn implicit into explicit, ambiguous into clear, and scattered bits and pieces into a connected and coherent big picture view, not just for software systems architecture but for any subject I’m concerned with.

I’m a productivityist. I used to be a perfectionist; I do not produce garbage.

I like watching sci-fi, fantasy and documentary; listening to 80s; reading technical and scientific books. I am also very much interested in linguistics, cognition, philosophy and various meta things.
