Aquarel offers six specialized software engineering rescue services led personally by Principal Engineer Dositej Grbović: three Core Demand Pillars (Vibe-Code App Rescue, Scaling-Wall SaaS Refactoring, and Membership & Stripe Billing Stabilization) and three Platform Spokes (Lovable + Supabase, Bolt.new & v0 Next.js, and Claude Code, Cursor & Replit). Every engagement begins with a free 20-minute Triage Call and $0 48-hour Codebase Audit.

Filter by your primary production symptom to see the root technical cause, recommended Service Landing Page, and pre-filled Triage Call link:
AI Prompt Regression Loops 1–2 Weeks • Starts at $1,000–$1,500+
"Every new prompt in Claude Code, Cursor, Replit, or Lovable fixes one feature and breaks two others"
Root Cause: 3,000-line monolithic god-components, circular state dependencies, and missing repository-level CLAUDE.md / AGENTS.md architectural boundaries.
Surgical Fix: Decompose god-files into isolated domain modules and lock core auth/billing behind custom CLAUDE.md, AGENTS.md, and .cursorrules guardrails.
Bolt/v0 & Next.js Build Crashes 5–10 Days • Starts at $1,000–$1,500+
"App works in Bolt.new or v0 preview, but fails next build, drops SSR sessions, or crashes on deploy"
Root Cause: Server-only imports leaked into Client Components, unguarded React Server Actions, SSR hydration mismatches, and corrupted Stripe raw webhook buffers.
Surgical Fix: Separate Next.js Server/Client boundaries, wrap Server Actions in session + Zod validation, and configure zero-error production CI deployments.
"Production SaaS dashboard freezes under real concurrency, WebSockets crash, or upgrades risk downtime"
Root Cause: Unbounded component re-renders, N+1 API waterfalls, unisolated WebSocket background workers, and brittle deployment scripts.
Surgical Fix: Profile render flamegraphs, decouple state stores, harden WebSocket supervision, and ship strangler-fig modernization with zero downtime.

Frequently Asked Questions
Should I choose a Core Demand Pillar or a Platform/Stack Spoke?
+
Both lead directly to Principal Engineer Dositej Grbović and follow the exact same 4-Step Offer Ladder (Free 20m Triage Call → Free 48h Codebase Audit → Fixed-Scope Rescue Sprint from $1,000–$1,500+ → Optional Fractional TechOps Retainer). Choose a Platform Spoke if your app was built primarily in Lovable + Supabase, Bolt.new/v0 + Next.js, or Claude Code/Cursor/Replit. Choose a Core Demand Pillar if your app spans multiple tools, hits a B2B SaaS scaling wall, or suffers from active Stripe/membership billing leaks.
What is the Mandatory Proof Triad included on every Service Landing Page?
+
Every Aquarel Service Landing Page embeds three verified proof assets directly above the conversion CTA: (1) a matching Career Rescue Case Study documenting real production outcomes, (2) 1 to 5 code-backed Technical Teardowns with copy-pasteable CLAUDE.md or AGENTS.md guardrails, and (3) a direct preview link to our interactive Sample 48-Hour Codebase Audit Report (/sample-audit).
How does the Free 48-Hour Initial Codebase Audit ($0) work across all 6 services?
+
First, we talk live on a 20-minute Triage Call (or connect asynchronously within 1 business day), verify my identity, and execute a mutual NDA before you grant read-only repository access. Within 48–72 hours, I deliver a Red/Yellow/Green risk scorecard, a 10–15 minute plain-English Loom video walkthrough, and a fixed-price Rescue Sprint quote with zero obligation.
What if my production checkout, authentication, or server is down right now?
+
Every service supports our 24–48 Hour Emergency Stabilization Fast-Track (starting at $1,500). Select "🔴 Production Emergency" on /triage to bypass the standard audit queue and trigger an immediate [P0 EMERGENCY TRIAGE] alert to Dositej Grbović’s mobile device with a 2–4 business hour response commitment.
