Selection Contribution Platform, Retail Catalog. Responsible for systems that process earth's largest catalog data, owning everything around the system from deployments to monitoring and troubleshooting.

Software Development Engineer

.Net web development (business process management tool). Responsible for developing and maintaining a workflow engine running within Microsoft's IIS. The engine processed tens of thousands of workflows daily, forming the backbone of one of the largest banks in Turkey by providing a performant application for business to develop and perform various workflows such as loan applications or account opening.

Senior Software Developer

.Net development for the infrastructure of core banking application. I designed and implemented a workflow engine from scratch with Oracle as the storage. The frontend was implemented with WPF and the engine was a daemon performing steps asynchronously. This application served as the building block to create the new generation banking solution for the largest bank in Turkey with more than a thousand branches.

Software Specialist, Content Management Service

IPTV settop box software development. I've written modules in C to support teletext, subtitles and RTSP (real-time streaming protocol).

Embedded Software Developer


Created a product from scratch, which served as a storage solution much like dropbox. This involved C++ client application development using wxWidgets, openssl, libcurl, xerces-c and boost libraries. Server was implemented in Java with data encryption and delta updates to allow for a secure, fast and seemless experience for the end user.

Software Engineer

I've been developing serverless web applications and APIs using the serverless framework, making use of AWS lambda, step functions, APIG, S3, CloudFront, Route53 and CloudWatch (for events).

As an ex-Amazonian, I've developed many services backed by AWS. Leveraging cloudwatch to monitor system health or high throughput stream processing with kinesis and dynamodb just to name a few of my experiences with AWS.

Although I regard myself as a polyglot technologist, having worked with various software stacks, Java is my go-to language. I've developed and maintained daemons, REST services and Android apps with Java; often finding myself inspecting a heap dump for memory leaks or connecting to a remote JVM to debug problems.

I've created serverless backend APIs using Python3, with the serverless framework.
I've been using Python for scripting small tasks, such as a migration script or automating a test. I've also developed web applications on Django.

I believe in automating any routine we have in software development. I strive to maintain a deployment pipeline where engineers would have confidence pushing code. This can only be possible with proper testing. I aim to have pretty high unit test coverage (nope, 100% is not practical) and ensure every external dependency is covered via integration tests. Furthermore, for high quality and improved operational excellence, having a separate environment for testing against regressions and performance is crucial within a full CD pipeline.

Deploying and maintaining services on Linux require a great deal of knowledge with scripting languages and command line tools. Tailing through application logs grepping for a particular pattern is what I do daily to troubleshoot production problems. To hot-fix corrupt data or perform a migration, occasionally I need to get my hands dirty on a perl or python script. I have experience in things like monitoring traffic on a particular port or profiling a process in terms of I/O, CPU or memory utilization.

I've used postgresql on AWS RDS and have developed applications using postgresql and also performed migrations on the database.

I've developed REST compliant web services on nodejs, serving high TPS traffic.

Enthusiastic software guy - polyglot technologist.
