Build and evolve
B2B products, internal platforms, and new modules from architecture through production, delivered in increments people can review and use.
B2B software developmentThree lines of work
We enter through the problem, not a technology list
The starting point changes. The responsibility does not: understand the system, reduce risk, and leave a foundation your team can operate and evolve.
Modernize and rescue
Inherited or difficult-to-change systems: stability and observability first, then incremental evolution without impulsive rewrites.
Legacy application modernizationData and integrations
Pipelines, events, enrichment, interoperability, APIs, and data performance tied to the real operation.
Data engineering and integrationsWhere to start
Three clear ways to get started
The right entry point depends on which risk you need to reduce before committing to a larger implementation.
01Rescue
Rescue Diagnostic
For existing software that has become risky or difficult to change. We audit before promising a solution and deliver a stabilization plan with costs and timelines.
- Architecture and dependencies
- Prioritized technical and security risks
- Keep-versus-replace recommendation
- If we continue, the diagnostic fee is credited
02Validate
Product Sprint
For reducing uncertainty before a complete build. We define the product, test a prototype, and leave a technical plan you can execute with us or another team.
- Scope and acceptance criteria
- A working, navigable prototype
- Architecture decisions
- You can stop and keep the deliverables
03Build
Build and Evolve
For building an end-to-end B2B product or continuing after a diagnostic or Sprint. One team covers product, frontend, backend, integrations, and deployment.
- Product design and frontend
- Backend, APIs and integrations
- Testing, deployment, and observability
- Ongoing monthly collaboration available
The Rescue Diagnostic and Product Sprint start at USD $3,000. Full builds typically run between USD $16,000 and $65,000, depending on scope. We confirm the range before requesting access or committing to implementation.
We take on a small number of projects at a time so each one gets real focus and the same hands from start to finish, not a rotating team.
Behind each phase there is a method. The detail of how we design and build — discovery, specs, components and architecture — lives on its own page.
See how we buildRisk under control
Your company stays in control from day one
The engagement should be easy to start, review, and end. These terms are already part of how we work.
Your company owns the work from the first commit
The repository, code, infrastructure, and documentation remain in your name.
You can stop after the Sprint
Either side can decide not to continue. You keep the deliverables produced.
The team knows your whole project
We work on it directly and keep the context, with no rotating teams and no handoffs.
The diagnostic is not paid twice
If we continue with stabilization, we credit its value toward the project.
About
Direct engineering for products that cannot be left half-built
We are an engineering team with more than 14 years of combined experience across backend, architecture, distributed systems, product, and frontend. We cover design, frontend, backend, AI, mobile, and deployment without subcontracting the hard part.
We take on a few projects at a time. That means you always talk to the people writing the code: no middlemen, no context handoffs, no explaining the same thing twice.
And we take care of what shows up late: that the system holds as it grows, that another team can maintain it, that it doesn't go down at six on a Friday. Scalability, performance, availability, security, and maintainability aren't extras: they're what decides whether your product is still standing in three years.
What we build
- Custom software
- Web & mobile apps
- Platforms & SaaS
- APIs & microservices
- Artificial intelligence
Evidence, not promises
A small studio with experience in large systems
Experience matters when the data is real, the integrations are difficult, and a failed deployment has a concrete cost. This is what we bring to each project.

Codiva-owned products
Built by our team under codiva. They are not client engagements: open them and inspect the work.
Previous professional experience
- Tracktec
- Portavita Health
- Acronis
- Previsible
Work performed by members of our team as part of previous employment. These companies are not codiva clients and their names do not imply endorsement.
Cloud + events
A pattern for processing without blocking the system
Small APIs, asynchronous work, bounded memory, and traceability. The architecture changes with the problem; these boundaries do not.
Clean Architecture
The business does not depend on the framework
Dependencies point inward. The domain stays stable while the web layer, database, or cloud provider changes.
Code to production
Real gates before production
We design delivery with the software. Tests, review, security, and observability are part of the normal path.

FAQ
Frequently asked questions
What is codiva?
codiva® is an independent studio of two senior software engineers, based in Ñuñoa, Santiago, Chile. We build complete product — design, frontend, backend, and AI — from start to finish, with no juniors and no subcontracting. The people who sell you the project are the people who build it.
What services does codiva offer?
Three lines: Build and evolve B2B products, internal platforms, and new modules; Modernize and rescue inherited or difficult-to-change systems; and Data and integrations for pipelines, APIs, interoperability, and data performance.
Who owns the code?
You do, from the first commit. The repository is in your name and we hand over everything — code, infrastructure, and documentation — with no hidden dependencies or lock-in. If one day you want to continue with another team, you can.
Can you take over a project someone else started?
Yes. We take on inherited codebases — from a freelancer who left, an agency that changed direction, or a previous team — stabilize them, and keep building. This is exactly where more than 14 years of backend architecture and distributed systems make the difference.
What happens if the team gets sick or fully booked?
We take on a small number of projects at a time, precisely so we don't overcommit and can give each one real attention. The whole team knows every project, so nothing depends on a single person, and your code, infrastructure, and documentation always live in your repository. If timing needs coordinating, we tell you before we start, not after.
Do you work with internal teams or replace them?
Both. We embed with your internal team when there is one, or act as your full product team when there isn't. We adapt to how you already work.
How much does a project cost?
It depends on scope, but we won't make you guess. A Product Sprint starts at USD $3,000 and a full product usually runs between USD $16,000 and $65,000. On the first 30-minute call we give you a real range — not a 20-page proposal three weeks later.
How long does it take?
A Product Sprint is 1–2 weeks. A full product runs between 6 and 16 weeks depending on scope. We put a date in the proposal and flag it the moment anything puts it at risk — we would rather have an awkward conversation early than a surprise at the end.
What if it doesn't work out or we're not happy?
That's exactly what the Product Sprint is for: 1–2 paid weeks with concrete deliverables, at the end of which either side can decide not to continue — and you keep the prototype, the architecture decisions and the technical plan regardless. It's the cheapest way we know to find out whether we work well together.
