Gediminas Ubartas
Hello, I'm Gediminas Ubartas,

IT consultant/Software developer

I'm a full-stack engineer with over 15 years of experience building scalable applications and leading development teams across fintech, e-commerce, and sports technology. Throughout my career, I've enjoyed solving complex technical challenges, designing robust system architectures, and guiding teams toward delivering products that make a real impact.

My 5-Step Collaboration Process

A structured approach to successful collaboration and project delivery

My approach to a successful collaboration is to begin with a discovery of the present state of your project, problem, or demand, then scope out the engagement where I can add value and plan the implementation appropriately.

I consider adequate communication to be a critical component of success. As a result, I propose the following phases as a cycle of our collaboration:

1
Discovery

Remote Sessions

Begin remote session(s) for scoping and planning. We'll explore your project's current state, identify challenges, and define clear objectives for our collaboration.

2
Assessment

Trial Assessment

An assignment for me to serve as a trial assessment for both parties to see whether we are a good match to work together effectively.

3
Execution

Delivery

Delivery of the work with consistent communication, regular updates, and adherence to agreed timelines and quality standards.

4
Review

Evaluation

Evaluation of outcomes and results together, gathering feedback and ensuring all objectives have been met to your satisfaction.

5
Iteration

Repeat Cycle

Repeat the cycle for further work objectives (if any), building on our established collaboration and continuous improvement.
