    I am a Principal Software Engineer with over 7 years of software development experience. I help businesses with complicated business logic to implement scalable technical solutions by designing software architecture and applying it. Throughout my career, I worked as a Software Developer and Software Architect. I’ve worked with startups and with companies having dozens of billion dollars in yearly recurring revenue. I’ve worked on projects of different sizes, from small ones where I was the only technical person to huge ones where I had five teams working concurrently by use of Jira, slack and GitLab. So that you can get an idea of my type of work and working together would look like, Following are some of challenges that I am faced with when designing and implementing the system: 1. System should handle millions of transactions per day that have to be reported in a timely manner. 2. System should be tolerant to hardware failures, including the loss of the entire data center. 3. Multiple developers should be able to work on the project productively with minimal conflicts. 4. Correctness of reporting is essential - every introduced bug can have disastrous consequences - the system should have checks in place that prevent buggy code from being deployed to production. 5. Transaction reporting domain is very complicated, and business requirements are frequently changing. System design should be flexible enough to adjust to the required changes. 6. There are multiple stakeholders involved; each has different requirements for the system. I am devoted on a great deal of attention to solving most challenging problems in the engineering world by building a system that supports 'exactly once' end to end processing semantics (that means that every message is processed exactly once, with no message loss or duplication). If you're willing to work with me - write me Thanks.
