Production Stabilization & Concurrency Remediation

Fragile Codebase → Production-Grade System

Production Stabilization & Concurrency Remediation illustration

A codebase that works in demo will not survive production. No tests catch regressions, no monitoring alerts you when users hit failures, and under concurrent load, unguarded shared state turns into race conditions in order, payment, and inventory flows.

Obox Systems is an international software engineering company headquartered in the US, specializing in stabilizing systems built fast — AI-assisted prototypes, rushed MVPs, and codebases that outgrew their first architecture. Engagements are led by our CTO, backed by a structured team with mandatory peer review; NDA available on request.

We audit and refactor these codebases into production-grade systems — security hardened, tested, observable, deployable — in weeks, not the months a full rewrite takes. Every file is triaged as Keep, Refactor, or Replace, preserving validated product decisions.

Proven: a Node.js bottleneck rewritten in Rust behind the same API delivered 10x throughput.

We can help you with:

  • Codebase audit with file-by-file triage: Keep / Refactor / Replace
  • Security hardening — input validation, auth middleware, secrets management, dependency audit
  • Concurrency remediation — race conditions in order, payment, and inventory logic eliminated
  • Automated test suite — unit and integration tests for critical paths
  • CI/CD pipeline — GitHub Actions, staging environment, automated deployment
  • Architecture refactoring — folder structure, separation of concerns, dependency cleanup
  • Performance optimization — database indexing, query optimization, caching
  • Production deployment — monitoring, error tracking (Sentry), logging, backup strategy
  • Rust rewrite of performance-critical paths when Node.js or Python hits scaling limits

The Diagnostic Architecture Audit maps your codebase’s security, test coverage, and architecture in five days — a file-by-file triage report you own.

Milestone-based

Case Studies

FAQ

  • Rewrites discard validated product decisions — UI flows users navigate, business logic handling edge cases, working integrations. We preserve what works (typically 50–70%) and fix what doesn’t. Faster, lower risk.

  • Cursor, Copilot, Bolt.new, Lovable, Replit Agent, v0, ChatGPT-generated code. The failure patterns are consistent regardless of which tool generated the code — missing tests, no error handling, duplicated logic.

  • The Diagnostic Architecture Audit scans for security vulnerabilities, measures test coverage, maps architecture, and produces a file-by-file triage report (Keep / Refactor / Replace) you own regardless.

  • Yes. We refactor in your stack — React, Next.js, Python, Node.js. Rust rewrites are surgical, only for bottlenecks where your current stack hits performance limits. Same API, better throughput.

  • Our audit tells you honestly. If refactoring cost exceeds rewrite value, we recommend our SaaS Development service instead. A five-day audit prevents a costly rebuild mistake.

  • Yes. We sign NDAs before any technical discussion begins, on request.

  • You do. IP, source code, architecture docs, and deployment runbooks are fully assigned to you on completion — no vendor lock-in.

  • Yes. Signed contracts with fixed scope per phase. Wyoming LLC — you’re contracting with a registered entity, not an individual.
