• Feature delivery
• Unit testing
• Scope management

One of the biggest sportswear companies’ order management services had to make dependencies upgrade, interface redesign. I was responsible for creating roadmaps to accomplish business goals, along with architectural support, analyzing the existing code base and refactoring proposals. There were two apps: responsible for B2B orders and responsible for access management. Applications were written on Vue as a POC originally but after lots of iterations became a legacy center so required treatment.

• Analyzing of ways for redesign implementation
• Redesign roadmap creation
• Migration roadmap creation
• Description of technical stories
• Analyzing of the solution’s code base
• Refactoring & refactoring proposals
• Merge requests review

Not a specific project but a group of activities like supporting pre-sales, R'n'Ds, etc.

• R’n’D conducting, requirements definition, documentation
• Pre-sales technical support, proposals, estimations
• Technical articles writing
• Educational courses creation
