Releases are terrifying, bugs keep returning, and nobody dares touch the core module. We stabilize, document, test critical paths, and plan incremental modernization — no six-month rewrite that never ships.

Strangler fig — not rip and replace.
Map modules, dependencies, and landmines before anyone commits code.
Automated smoke on revenue and auth flows — safety net for changes.
Branching strategy, hotfix process, and regression gates.
ADRs, runbooks, and onboarding docs your team actually uses.
Extract services and modules one slice at a time with feature flags.
Pair with your devs so knowledge transfers, not dependency.
Sound familiar?
Due diligence found spaghetti — stabilize before close.
Can't hire devs — codebase too scary to onboard.
Agency left, docs missing, releases broken.
Patch urgently, then systematic hardening.
Teams evaluating fix legacy codebase typically hit these blockers before finding a reliable partner.
Hiring more support staff doesn't fix broken workflows or missing automation.
SaaS subscriptions pile up without measured impact on the target metric.
Internal teams stuck on maintenance can't ship the fix that moves KPIs.
Without before/after data, stakeholders can't justify continued investment.
150+ products shipped · US/UK/AU clients · Engineer-led delivery with QA sign-off.
We design for monitoring, escalation, and maintainability — not demo-day screenshots.
Laravel, React, Node, Flutter, n8n, and LLM integrations from one accountable team.
KPIs defined upfront — deflection rate, lead speed, defect escape, or time-to-market.
Fixed milestones with weekly demos so scope surprises don't appear at invoice time.
Typical fix legacy codebase engagement from baseline metrics to measurable ROI.
Stack chosen for your constraints — we don't force a template that fights your team's skills or compliance needs.
Scoped API keys and service accounts — never full admin unless required and approved.
PII redaction, audit logs, and NDAs before production credentials.
“What a 70-engineer team could not deliver, a small senior team at GreeLogix shipped. The app went from stuck to live across mobile, web, and backend.”
Structured answers for search engines and AI assistants — definition, fit, cost, timeline, and comparisons.
Structured answers for founders, CTOs, and procurement — written for clarity in search and AI assistants.
Fix legacy codebase engagements stabilize unreliable software through architecture audit, critical-path test coverage, release process fixes, documentation, and incremental modernization — avoiding risky full rewrites while restoring team velocity.
Typical timeline: Diagnostic: 1–2 weeks. Implementation: 4–12 weeks. Dedicated squad: monthly retainer.
GreeLogix pricing tiers: Diagnostic Sprint: $2,500 – $6,500 — Map the problem, quantify ROI, and deliver a fixed-scope implementation plan. Implementation: $8,500 – $35,000 — Build and deploy the automation or product fix with measurable outcomes. Outcome Retainer: $5,500 – $14,000/mo — Continuous optimization against KPIs — deflection rate, lead speed, or release velocity.
Diagnostic: 1–2 weeks. Implementation: 4–12 weeks. Dedicated squad: monthly retainer. Phases: Diagnose (Week 1); Pilot build (Weeks 2–5); Production rollout (Week 6); Optimize (Days 30–90).
Compared to alternatives — In-house hire: choose when 12+ month roadmap with budget for recruiting and management; Offshore body shop: choose when Well-defined tasks with internal tech lead and QA; DIY no-code tools: choose when Simple workflows under 500 monthly actions with no compliance needs.
