You built your product with AI tools. It works, users are on board, but when investors ask about due diligence and regulators ask about compliance, Supabase and Vercel won't cut it. We move your stack to production-grade AWS in under four months, at a fixed price, with zero downtime.
Multi-account Landing Zone, RDS Multi-AZ, ECS Fargate, KMS encryption, GuardDuty, CloudTrail. Everything configured correctly from day one: reproducible, auditable, investor-ready.
Standardised NestJS backend with reusable modules for auth, business domains, documents, payments, audit, observability, and generated frontend clients. The kind of stack that attracts talent instead of repelling it.
Field-level AES-256-GCM encryption, MFA via Cognito, audit logging via CloudTrail, and access governance via SCPs. The architecture gives teams the technical controls needed for compliance readiness.
Complete framework with documentation, runbooks, and AI development configuration. You can continue building independently. We're available on retainer, but you're never locked in.
Problem
Investors are asking about your infrastructure and your Supabase/Vercel stack can't demonstrate maturity
We deliver a multi-account AWS Landing Zone with governance, monitoring, encryption, and CI/CD. The exact infrastructure stack that passes due diligence. Ready in weeks, not months.
Problem
Regulators require encryption, audit trails, and access controls (NIS2, DORA, GDPR)
Application-level AES-256-GCM via AWS KMS, CloudTrail for audit, Cognito with MFA, NestJS Guards replacing Supabase RLS. Compliance-supporting controls are built into the architecture, not bolted on after.
Problem
A software house quoted £200K+ and six months of work
Our repeatable framework, built once and deployed many times, brings the cost down to from £12K. AI-accelerated delivery means one engineer produces what normally takes three. Scale advantage, not cheap labour.
Problem
Traditional migration takes too long and you cannot wait six months
Fourteen weeks, four phases. Your old stack keeps running in parallel throughout. Zero disruption to users. The switch happens only when everything is verified and ready.
Problem
No DevOps team or backend engineer to lead the migration
Fully managed by a two-person senior team (Solutions Architect + Full-Stack Engineer). We handle everything: infrastructure, backend, frontend switchover, go-live. You focus on your product.
Problem
Fear of being locked into the migration partner
We hand over the complete framework with documentation, AI coding configuration, and runbooks. Any competent engineer can continue the work. If you want us back, we re-engage instantly because it's our known stack.
| Traditional agency | AI tools (Lovable, Cursor) | SmartVibe | |
|---|---|---|---|
| Cost | £60K to £200K / €70K to €240K | £0 to £5K (but not production) | from £12K / €15K |
| Time to production | 26 to 52 weeks | Days (but not real production) | 10 to 16 weeks |
| Infrastructure quality | Custom, often manual | None | Production-grade, reproducible IaC |
| Post-delivery development | Dependent on the agency | You're alone | AI-assisted with guardrails |
| Client independence | Low (only they know the code) | High (but no quality) | High (framework you can take over) |
| AWS consumption | Variable | Zero | Full stack, grows with your product |
Every migration lands on the same standardised target stack. We know it deeply, have comprehensive documentation, and deliver it faster each time. This is a product, not a bespoke engagement.
AI generates code from your existing codebase. Humans make architecture decisions, validate security, and own the output. You get startup speed with enterprise quality controls.
Your product keeps running on the old stack throughout the entire migration. The switch happens after feature-parity testing is complete. Your users notice nothing.
A typical migrated startup runs on approximately £120/month of AWS at initial user volumes. Scales predictably with growth. No surprise bills, because the standardised architecture has known cost curves.
Fintech, healthtech, legaltech: we design for NIS2, DORA, GDPR, FCA, and PSD2 from the start. Encryption, audit trails, access governance, and MFA are in the base stack, not optional add-ons.
Devopsity is an AWS Advanced Partner since 2014. Well-Architected Programme member. Service Ready for ECS/EKS. Confirmed AWS DevOps Competency, AWS Security Competency in progress. Your migration is backed by a decade of AWS project experience.
Four phases, typically fourteen weeks. Your existing product keeps running throughout. Fixed price agreed upfront based on an assessment of your codebase.
We lay the groundwork: AWS infrastructure defined as code, dev/staging/prod environments, the first application module running with authentication and encryption. By the end of week two you have a working development environment with a CI/CD pipeline.
We build all domain modules for your application. Your existing code is reverse-engineered into specifications, then AI-assisted generation produces the NestJS modules. By the end of this phase you sign off a working staging environment with the full API.
Deterministic migration scripts replace all Supabase calls in your frontend with generated API hooks. No manual rewriting. By the end, Supabase is completely removed from the codebase and you sign off full feature parity.
Production infrastructure ready, tested, and verified. We switch DNS and launch production. The old stack stays on read-only standby in case a rollback is needed.
| Layer | Technology | Why |
|---|---|---|
| Frontend | React + TypeScript (existing, migrated) |
Most vibe-coded apps are React SPAs. Frontend carries over; we replace the service layer. |
| Backend | NestJS on ECS Fargate |
Standardised NestJS backend with reusable modules for auth, business domains, documents, payments, audit, observability, and generated clients. |
| Database | RDS PostgreSQL Multi-AZ |
Managed relational DB with high availability. Direct migration from Supabase PostgreSQL. |
| Auth | AWS Cognito + MFA + OIDC |
Managed auth with MFA, social login, strong auth federation. Replaces Supabase Auth. |
| Encryption | AES-256-GCM via AWS KMS |
Application-level field encryption. Replaces pgcrypto. Per-field, auditable. |
| IaC | Terraform |
Full infrastructure as code. Landing Zone, dev/staging/prod. Modules from our platform. |
| CI/CD | GitHub Actions, ECR, ECS |
Trunk-based dev, environment promotion, manual approval gate for production. |
| Monitoring | CloudWatch + X-Ray + GuardDuty |
Observability from day zero. Dashboards, alarms, tracing, threat detection. |
| Edge | Cloudflare Pro (WAF + CDN + DNS) |
DDoS protection, caching, SSL termination. |

Not sure about scope or cost? We'll review your codebase and tell you exactly what the migration involves: timeline, cost, and what carries over vs. what gets rebuilt. No commitment.
Share your repo (read access). We assess: number of entities, complexity of business logic, auth model, data sensitivity, integration points.
You receive a document with: estimated timeline, fixed price quote, migration approach, what stays vs. what changes, and risk factors.
The assessment is free. If the migration makes sense, we proceed. If it doesn't (too simple or too complex for this model), we'll tell you honestly.
