Diagnostic WarningSigns of Critical
Signs of Critical
Technical Debt.
If your Adobe Commerce build is exhibiting these symptoms, you aren't just losing speed—you are leaking revenue and risking system failure under peak load.
Your store feels heavy and slow, heavily penalizing your mobile conversion rates and Core Web Vitals.
Deployments are a gamble. You lack a zero-regression pipeline, making every update a risk to checkout stability.
You are drowning in technical debt caused by conflicting third-party extensions and bloated legacy code.
Critical data silos exist because your ERP, WMS, and marketplaces aren't seamlessly synchronized via robust APIs.
Your current agency operates like a 'black box', taking weeks to action critical security patches or version upgrades.
You are bleeding revenue through abandoned carts and poor search, but lack the technical architecture to implement data-driven CX.

Book a Technical AssessmentEvery rescue begins with a deep-dive Technical Discovery. We audit your codebase, database, and server logs to identify the root causes of instability. We then present a prioritized stabilization roadmap before writing a single line of code.
Yes. For the vast majority of our Magento 2 clients, we highly recommend migrating to Hyvä. It strips away the heavy JavaScript bloat of the default Luma theme, resulting in drastically improved mobile load times and Core Web Vitals.
Absolutely. While we utilize proven middleware where appropriate, our engineers specialize in building custom, secure API bridges for legacy or highly complex bespoke ERP and warehousing systems.
We offer flexible, SLA-backed retainers focused on 'Proactive Guardianship.' This includes scheduled security patching, continuous performance monitoring, and dedicated hours for iterative feature enhancements aligned to your growth goals.
Yes. Many clients start with a focused technical audit covering architecture risk, performance bottlenecks, extension conflicts, and integration debt. You receive a prioritized action plan with commercial impact framing.
