What we have built.

Featured · Travel & Holidays

Utazzo Holidays Platform Rebuild

A fast growing travel brand was held back by a monolith on Angular, .NET, and MS Access, slow and impossible to scale.

Web app, CRM, and admin rebuilt as microservices on AWS, with an automated lead pipeline and speed on low-end devices.

// WHAT CLIENTS SAY

The work speaks. Our clients confirm it.

“

They write code like it’s their own product. Every sprint felt like our engineers were fully invested in the outcome - not just closing tickets.

Founder · Series A SaaS Startup · Web application development

“

We went from concept to App Store in 11 weeks. The architecture they designed at the start meant zero rewrites - it scaled exactly as predicted.

CTO · Consumer Mobile App · React Native development

“

Our AWS bill dropped 40% in the first month. More importantly, our deployment pipeline went from a ritual to a button press. That’s the real win.

// INDUSTRIES WE SERVE

Where we have shipped.

We focus on engineering quality over sector specialisation - but these are the verticals where we have shipped repeated, comparable work.

SaaS & B2B Platforms

Multi-tenant apps, subscription flows, role-based dashboards, and enterprise integrations.

Consumer Mobile

iOS and Android apps shipped on React Native, with native modules where they earn their place.

Travel & Hospitality

Booking flows, inventory engines, and customer-facing portals built for real load.

AI & Data Workflows

Document processing, RAG chatbots, and structured-extraction pipelines in production.

Field Operations

Offline-first mobile, automated reporting, and image-recognition workflows for distributed teams.

Internal Tools

Admin panels, ops dashboards, and pipelines that make the team faster, not the customer.

// HOW WE MEASURE SUCCESS

Results that survive launch.

A shipped product is not the same as a successful one. We agree the measurement upfront and instrument it before launch - so the wins are real, not retrofitted.

Business outcomes first

Every engagement opens with a one-page success doc - the metric that matters to the business, measured the same way before and after.

Instrumented at launch

Analytics, performance monitoring, and error tracking are wired into the first deployment, not bolted on six weeks later.

Honest post-launch reviews

At 30, 60, and 90 days we run a written retrospective - what worked, what missed, what to change. We send it whether the numbers are good or not.

No vanity metrics

We do not count uptime above 99.9% as a win unless your business actually needs it. We report on what moves your revenue, retention, or cost line.

// EVERY PROJECT FOLLOWS THE SAME PROCESS

Discover → Architect → Build → Deliver → Grow

Every engagement starts with understanding your business, not your feature list. We design the system before writing code, build in two-week sprints, and deliver with monitoring and support in place.

Questions about this work

Which Codevibe case studies can I read in full?

Two are published as complete write-ups. The Utazzo Holidays travel platform rebuild covers a customer web app, sales CRM and admin rebuilt on Next.js, NestJS and React microservices on AWS, with AI automating the sales pipeline. The Reelrr study covers a lead-generation website for a video reel production service, built on Next.js.

Why are some Codevibe case studies anonymised?

Several clients are under confidentiality agreements, so those engagements appear as anonymised case studies - the sector, technology stack, timeline and outcome are described, but the client is not named. The two named studies, Utazzo Holidays and Reelrr, are published in full with the client identified.

What technologies do these projects use?

Next.js and React on the frontend, NestJS and Node.js for APIs and microservices, React Native for mobile, and AWS for infrastructure, with LLM-based automation where it earns its place. Legacy migrations feature heavily: an Angular, .NET and MS Access monolith and a legacy PHP monolith were both moved onto modern stacks.

How long do Codevibe projects typically take?

The engagements shown here run from 6 to 14 weeks: an infrastructure overhaul in 6 weeks, an AI internal tool in 8, a consumer mobile app from validated concept to App Store in 10, a SaaS platform rebuild and a field operations app in 12, and a B2B platform redesign in 14. Larger multi-module rebuilds run longer.

What kinds of problems does Codevibe take on?

The common thread is systems that have outgrown their original build - monoliths that buckle under load, manual processes that need automating, and products that need to reach an app store or a fundraise on a deadline. The work spans SaaS rebuilds, mobile apps, AI tools, lead-generation sites and cloud platforms.
