Creating dynamic web applications; planning and designing sectoral automations from scratch and coding the layered architecture; Creating e-commerce structures from scratch or optimizing the existing structure, analyzing large-scale data and transforming data into meaningful and visual information, scaling projects with large traffic flows are my specialties.
I would like to introduce myself briefly:
My software life started in 1994 by studying computer technical high school. The first programming language I worked on was the Qbasic programming language. During my high school years (1997), I wrote a library automation program (QBasic) as a project. My first market experience is an inventory tracking program I wrote for a construction company in 1998.
In 1999, I started Kocaeli University Computer Education Department. I graduated in 2003. I learned many programming languages ​​(C, C++, Mathlab, SQL, VisualBasic, ActionScript 3.0). Again, during my school years, I signed many academic projects.
I have worked in many projects and companies since 2003:
I worked at Isar Computer between 2003-2009. In this process, I developed many desktop programs (stock tracking, pre-accounting, service tracking) for companies using VisualBasic and C#.
In 2008-2009, my interest in web technologies increased. This is how I learned PHP. Meanwhile, I started developing dynamic websites and applications.
In 2009-2013, I undertook the construction or optimization of many dynamic websites on the market as a freelance. I developed myself in HTML, CSS, MySQL, MariaDB, javascript, AJAX-JQuery with the projects I did in this process.
Between 2013 and 2015, I worked in a team that developed a large-scale logistics automation with cloud system technology for a large-scale logistics company. In this process, I used both SOAP and Rest Api technologies and increased my previous knowledge.
I started using Laravel Technologies since 2015. I also had experience on microservice architecture. I blended Laravel technologies with redis and RabbitMQ. I have worked with teams using Laravel in all the projects I have worked on for about 7 years. I worked as a team leader in 2 projects developed with Laravel.
I am a person who constantly develops himself and learns new technologies. I also love to teach and share my knowledge. Coding and nature walks are my hobbies. I always want to try to stay fit and live life happily.
