Developed high frequency trading back-end applications.

SGV provides financial services for its clients and partners via cryptocurrency solutions.I began from scratch for all projects that SGV had as an idea. I built a robust, responsible and prolific development team. I led the team, did resource and task planning, managed the technological roadmap and set the technical strategy of the company. Besides managerial tasks, I coded a significant part of the whole infrastructure and set up DevOps procedures and pipelines.Reported to the group owner.koinal.io: Koinal is a global coin-buying service which customers can buy cryptocurrencies 24/7 with their bank/credit cards and wire bank transfers. I named the product :) I designed the system architecture, coded most of the apis and integrated provider apis. I created and managed DevOps tasks and pipelines as well.koinal checkout: Checkout is a cryptocurrency card payments solution. It helps merchants to allow their users to buy coins with their debit or credit cards. All card processing, identity verification and fraud monitoring processes handling on api side. So, merchants being able to provide card payments solutions to their end-users without any hassle.Named the product as well and led the project from scratch to production phase. Designing, coding and deploying to production environment took 6-week hard work with just 3 team members. After release, checkout has reached its first 1M turnover in just a couple of days. Binance was the first merchant. 10+ merchants make use of this service right now.Bitpace: Bitpace is a cryptocurrency payment gateway providing fast, reliable, secure cryptocurrency payment services. It has deposit and withdraw functionalities via a single api.I designed the architecture of the system and coded most of the api. MVP was ready in 4 months. Bitpace provides its services to 10+ merchants at the moment.I also planned and executed a migration from IBM Cloud to Microsoft Azure for all projects above after their production releases.

I was responsible for delivering new features and products from idea level to release with best and most efficient way. Thus, I worked with product managers and business members about how product should work and what is the best solution.I prepared architectural design and visualise as documents. Made technical decisions, task plannings and assigned tasks to back end team members. Handed the documents out to the team and oversee the tasks being done. Also, helped the team to have a good understanding of the entire project and system architecture.Conduct code reviews, drive quality in code. Also, I wrote code with joy.My additional responsibility is install, configure, manage and maintain servers (web, Redis, MongoDB and others).
