You need to get a project off the ground
You have the idea and the business rules, but you need someone to design the architecture and build it properly from the start.
Software Engineering
We build and maintain the software your business runs on
Custom systems, integrations, applied AI, automation, websites, and cloud infrastructure. We take on new projects as well as systems already in production, and you work directly with the engineer leading the work.
No formal brief needed. A short description is enough to get started.
When companies call us
Where we usually help
Some companies come to us with a new project. Others already have a system in production and need someone to keep improving it, connect it to other tools, or fix problems that have piled up.
Your product needs to keep moving
The product is live and the backlog keeps growing. You need engineering capacity to keep up without breaking what already works.
Your tools don’t talk to each other
ERP, CRM, spreadsheets, and in-house systems with duplicated data and a lot of manual work to move information between them.
Production is causing headaches
Slow pages, recurring errors, risky deployments, or infrastructure nobody feels safe touching.
What we do
From development to infrastructure
We work across the whole software lifecycle: building, integrations, AI, deployment, and maintenance. You can hire us for one piece or hand us the whole thing.
Software development
Custom web systems, APIs, and backends, plus new features for products you already have.
For example: customer portals, admin dashboards, APIs, and complex business rules.
Applied AI and automation
We bring AI into your systems and processes: assistants that work with your company’s data, agents that carry out tasks, and automations that take repetitive work off your team.
For example: internal assistants, AI agents connected to your systems, and process automation.
Integrations and modernization
We connect systems, APIs, and third-party tools. We also modernize older applications step by step, planning the migration so operations keep running during the change.
For example: ERP and CRM integrations and legacy system migrations.
Infrastructure, cloud, and DevOps
We set up and look after cloud environments, deployment pipelines, monitoring, and the infrastructure that keeps your product online.
For example: cloud environment setup, CI/CD, monitoring, and cost reviews.
Production support
We investigate incidents, fix bugs, and improve performance in production systems. This is engineering support, with terms agreed in the contract.
For example: bug fixes, performance tuning, and ongoing maintenance.
Websites and landing pages
Fast, well-structured company websites and landing pages, ready for leads and campaigns.
For example: company websites, product pages, and lead capture pages.
Don’t see what you need?
Tell us about it anyway. If it’s a software engineering problem, we’ll give you an honest answer about whether we can help.
How we start
It starts with a conversation
Before any proposal, we want to understand your situation: what exists today, what needs to change, and what matters most.
- 1
Tell us what you need
It can be an idea, a system with problems, or a list of improvements. No formal document required.
- 2
We recommend a path
After the conversation, you get a proposal. When there’s a lot of uncertainty, we suggest starting with a technical assessment or a smaller pilot.
- 3
We get to work
It can be a fixed-scope project or an ongoing monthly engagement, whichever fits best.
Summary after the first conversation

Experience
What we’ve done
Current Ternavisk work in Brazil and the United States. To protect confidentiality, we don’t name clients or share details that could identify them.
Recurring billing, checkout, and invoicing
A new billing and wallet solution, from the architecture to the screens, with recurring charges, checkout, and a customer area. It connects to third-party payment and tax invoicing services.
Moving to .NET 10 without putting production at risk
Legacy applications migrated from .NET Framework to .NET 10, with new AWS environments, deployment pipelines, regression tests, and a quick rollback plan in case anything went wrong. We also removed unused cloud resources to cut costs.
Keeping an online learning platform running
We handle deployments, version control, and Azure infrastructure, keep an eye on stability, and investigate incidents such as slowdowns in production. We also advise the client’s developers, working in English every day.
Applied AI for students
We started with a test in production to measure whether students wanted an AI assistant. The project was approved, and we’re now building the full version, with an admin panel to track usage.

FAQ
Common questions
Do you only work on existing systems?
No. We build projects from scratch and also take over systems that are already in use.
Who will work on my project?
Bruno coordinates the work and takes part in the technical decisions. Depending on the size and the skills needed, other professionals join the project, always coordinated by Ternavisk.
Do you work with AI?
Yes. We integrate AI models into existing systems, build agents that carry out tasks, and automate processes. Before proposing AI, we check whether it actually solves the problem.
How does support work?
It’s technical support for production systems: investigating errors, fixes, performance, and maintenance. Hours, response times, and channels are defined in the contract. 24/7 on-call coverage is not part of the standard offer.
How do we start, and what does it cost?
The first conversation is free. After that, we send a proposal: a fixed-scope project, an ongoing monthly engagement, or, when there’s more uncertainty, a technical assessment first.
Do you work with companies outside Brazil?
Yes. We already work on systems for companies in the United States, communicating in English every day. Terms are agreed for each contract.
Which company signs the contract?
Ternavisk is the commercial brand of Ternavisk Soluções em TI, a Brazilian company. The contracting entity is always stated clearly in each contract.
