Senior Software Engineer

I am a software engineer who has worked in enterprise software development projects for over 25 years. I worked as a software development engineer, project team leader, and branch manager gradually in my professional life.

After working as a civil servant, I retired in January 2020. I am currently working as a senior software engineer in a private company in Ankara, Turkey. I am planning to extend my profession abroad. I want to work in a job where I can gain further experience, and make contributions with my experience.

I am an ambitious, enthusiastic and open-minded professional. I am a fast learner and can adapt to different environments quickly. I am a good instructor and I like to share my knowledge and experience. I am a hard worker, team player and problem solver. I love to learn and work on challenging new technologies.

I took part in analysis, design, front-end & back-end development of various high volume / large scale projects that served over 1000+ users in corporate intranet. Those projects were mainly about document management, business workflows, social network analysis (SNA) and web mining.

As a senior software developer, I intensely made use of parallel programming, application & data security, auditing, authentication & authorization, text retrieval systems, object relational mapping (ORM), multi-layer application servers, SOA and REST services, and many more diverse concepts. I am especially experienced in Windows environment, .NET programming, and web based technologies.

I prefer to work as a senior backend/frontend developer or as an application architect.
