    Frequently Asked Questions

    Project-based development has a defined scope, fixed deliverable, and end date — you pay to build a specific thing. Managed services is ongoing: a dedicated team operates and evolves your platform week by week. Use project-based when the scope is well-understood and the work has a clear end. Use managed services when you need continuous improvement, on-call support, or fractional engineering capacity. Scalexa offers both, billed weekly on actual hours worked.

    Senior engineers only. Every Scalexa engineer has 10+ years of production experience. We do not employ juniors, interns, or offshore code mills. This is the single most important reason mid-market and Fortune 500 clients hire us: every line of code is written by someone who has shipped at scale before.

    Weekly billing on actual hours worked, not fixed-price estimates. Before any build, we run a paid Scoping exercise (Architecture Assessment $2K–$15K+, Code Audit $3K–$5K) that produces a realistic time and cost range. We refuse to do free estimates because they reward over-promising and create misaligned incentives. Weekly invoices show exactly which engineers worked which hours on which tickets.

    Yes — we run a service called Vibe Coding Rescue specifically for failing projects built by junior teams, offshore firms, or AI code generators like Lovable, Cursor, or Bolt. We start with a Code Audit ($3K-$5K) that produces a written diagnosis, a triage plan, and a rebuild-versus-salvage recommendation. Most rescues are salvageable; the ones that aren't, we tell you straight.

    We're stack-agnostic and pick what fits the problem. In practice, our most common stacks are: TypeScript/React/Next.js for frontend, Node.js or Python (FastAPI, Django) for APIs, PostgreSQL or DynamoDB for data, AWS or GCP for infrastructure, Terraform for IaC, and GitHub Actions for CI/CD. For AI/ML work we layer in Python with PyTorch, TensorFlow, Hugging Face, and the major cloud ML platforms.

    Every project ends with a written handover document (architecture diagrams, runbooks, on-call procedures, deploy guides, known issues), a recorded walkthrough for your team, and 30 days of post-handover support included. Source code lives in your Git org from day one, not ours. We do not hold infrastructure or credentials hostage.
