Technical Lead

I am a software developer with 12 years of commercial programming and team leading experience. I am interested in working on very complex projects involving many different technologies. I am very good at figuring out how such projects work and understanding what needs to be done even if previous developers are long gone, there is no documentation and it is not possible or very hard to find a developer who knows all technologies being involved in a project. I can lead existing and new developers in such projects but also code myself. I can architect complex projects from scratch. I know how to create long term plans of execution to achieve a specific goal and then to actually execute that plan. I am very good at extracting requirements from clients who usually think in very abstract and general ways and converting them to a format that developers can actually work with. My main skills include: ✓ Android apps ✓ iOS apps ✓ Deep learning and Google TensorFlow ✓ Crypto platforms: BitCoin, Ethereum, EOS, NEM ✓ PHP/Python/JAVA backends ✓ Amazon Web Services and complex server infrastructure administration ✓ Spring Framework ✓ Pivotal Cloud Foundry ✓ Augmented Reality ✓ Team leading

Five Stars is not enough! re4ct0r consistently exceeds our expectations. He has a tremendous ability to understand BOTH the business requirement as well as the technical task. Because of this re4ct0r raises pertinent issues that shape the strategic direction of the project and then executes on the agreed solution in the most efficient way. He does in 1 hour what it takes lesser freelancers to do in a day (if at all). Our highest endorsement and true appreciation goes to re4ct0r!
