Technology FAQ
Practical questions about stack and architecture.
How does Uokal choose a technology stack?+
We begin with users, workflows, data sensitivity, integrations, scale, team capability, deployment constraints, and expected product life. Technology follows those needs.
Do you always use the newest framework version?+
We prefer supported, stable releases after checking ecosystem compatibility, operational risk, security, and migration cost. Newer is useful only when it improves the outcome.
Why do you use TypeScript?+
TypeScript makes contracts visible across components, APIs, models, and business rules. It improves tooling and makes change safer as products and teams grow.
When would you choose PostgreSQL over MongoDB?+
PostgreSQL is our usual choice for connected operational records and transactions. MongoDB is considered for bounded document workloads where its data model is a genuine advantage.
Can you work with our existing technology stack?+
Yes. We first assess architecture, support status, team knowledge, security, deployment, testing, and change risk before recommending integration or modernization.
How do you prevent cloud costs from growing unexpectedly?+
We define ownership, observe usage, cache deliberately, right-size services, use lifecycle rules, avoid premature complexity, and review cost alongside performance.
What makes an architecture AI ready?+
Clear APIs, governed data, observable workflows, safe permissions, asynchronous processing, evaluation boundaries, and vendor-independent integration points create useful readiness.
How do you test critical workflows?+
We combine typed contracts, focused unit tests, integration tests, browser automation, manual exploration, accessibility checks, and production monitoring based on business risk.
Do you use microservices?+
Only when independent scale, ownership, deployment, or reliability justifies the operational cost. A modular monolith is often the better starting architecture.
How do you keep software maintainable long term?+
We use explicit boundaries, readable code, automated quality checks, controlled dependencies, documentation, observability, and regular maintenance rather than relying on cleverness.
