Hello! My name is Deiby Dayans and I have been a professional software developer for more than 12 years. I also have a full-time professional team of developers specialized in DevOps, Full-Stack, and Low Code approach. You've probably seen the value of a good architecture in Full Stack Development, and early figuring out good Database Architecture in API design. But will it ensure that things will be done AS EXPECTED? Here is the thing: Whether it's coming up with software development, API Integrations, or Migrations you have to see the value of planning, following up, and prototyping to land mental models of the Big Picture. I see that. Do you? If you're not sure about that, think about this situation: Are you confident in your list of tasks or the backlog provides the necessary information to believe things will be DONE as expected? This can be as frustrating as having stressful calls with developers who do not keep track of results. You may find yourself in a situation where deadlines are approaching and you need to present product features to your CLIENTS, USERS, or MANAGERS from your department. And when the proof of concept fails. That sense to be honest kills you! At the end, you have to be in a meeting asking to reschedule the DEMO day or release date if necessary. Okay! Think of me as the person who will support to you to get the things DONE and will try to figure out CORNER cases. I am a hardworking professional willing to go the extra mile for my clients - just read what those clients have said below! By taking on the project(s) with an attitude as if I'm the owner of the product or business and with the following aptitudes: - Planning. - Methodologies. - Prototyping. - Clean Coding. - Clean Architecture. - SOLID. - Test Design. - Stress Tests. ** TO ENSURE COMPLIANCE WITH UPWORK'S TERMS OF SERVICE , PLEASE REFRAIN FROM SENDING OR SHARING ANY CONFIDENTIAL INFORMATION OR SPECIFICS OF YOUR REQUIREMENTS MATTER PRIOR TO THE INITIATION OF A FORMAL PROJECT OR A PAID CONSULTATION.
