How the work runs
Clarify the goal
The first step names the business process and the systems already in place. Wishes that are not in scope stay listed as excluded.
Fix architecture and scope
Data flows, boundaries and modules are written down before code. The estimate refers to this text, not to a verbal number.
Build and integrate
Development, security and operations follow the same plan. Integrations to ERP, payment and channels stay traceable.
Hand over and portfolio
Completed work appears in the public portfolio where it fits the engagement. Operations and documentation match what was agreed.
Posts
These posts were written by Rouslan Trouchkovskii at United Solutions.
Headless commerce in stages, not in one cut
A monolith switch on a weekend is a rollback plan, not a migration strategy.
Where card data stops touching the shop
If card data can reach the shop database, the boundary drawing is wrong and is fixed before launch.
Legacy ERP without a big-bang switch
A one-night ERP cut-over is a plan for lost orders unless every path was rehearsed in writing.
Architecture on paper before the estimate
A verbal architecture is not a scope. The estimate points to the paragraph that names modules and exclusions.
Scaling e-commerce without stopping sales
A peak that only works after manual cache clears is not scaled; it is postponed.
