Technical consulting in software architecture and technology
Software technical consulting is the independent assessment of systems, architecture and engineering practices to support evidence-based technology decisions. Wisalo, a software house based in Curitiba, Brazil, founded in 2019, combines strategy and execution: we diagnose, recommend and, if you want, help implement the changes.
Overview
Technology decisions, such as choosing a stack, architecture or cloud provider, or rewriting a system, have an impact for years and are expensive to undo. An experienced outside perspective helps you see risks, compare alternatives and decide with clarity about the trade-offs.
Our recommendations are practical and prioritized. Instead of a generic report, we deliver a diagnosis backed by evidence from your own code and operations, an action plan ranked by impact and risk, and a record of architecture decisions, so your team knows the reasoning behind each choice.
The consulting is led by professionals who also build and operate software every day, which keeps recommendations close to the reality of those who will carry them out. We assess not only the technology but also how the team works: version control flow, code review, testing, releases and observability. When a recommendation involves a decision that is hard to reverse, such as switching databases, languages or cloud providers, we make explicit the risks, the migration costs and the conditions under which another alternative would be better.
Who it is for
Leaders who need to make technology decisions
Directors and managers who need an independent technical assessment before investing.
Companies going through investment or acquisition
Organizations that need to understand the quality and risks of a piece of software before a business decision.
Teams with accumulated technical debt
Teams that feel every delivery is getting slower and want a realistic plan to recover the codebase.
Companies undergoing digital transformation
Businesses that are digitizing processes and need a coherent technology roadmap.
Problems we solve
Unsure whether to rewrite or evolve the system
We assess the code and architecture and recommend the lowest-risk path for the business.
Stack choices without clear criteria
We compare alternatives based on requirements, team, cost and ecosystem, and record the decision.
Architecture that can't keep up with growth
We identify bottlenecks and propose a target architecture with a gradual transition plan.
Unknown security and LGPD risks
We review authentication, authorization, secrets management and personal data handling.
Tech team without a best-practice reference
We mentor on architecture, testing, code review and continuous delivery.
What we deliver
Technology assessment
Evidence-based diagnosis of architecture, code, infrastructure, security and delivery process.
Systems architecture
Design of the target architecture and transition plan, with decisions documented in ADRs.
Code review and technical debt
Code review with a technical debt map prioritized by impact and effort.
Stack selection
Comparative analysis of languages, frameworks and cloud services for your context.
Digital transformation roadmap
A technology evolution plan aligned with business goals, broken into stages.
Tech team mentoring
Guidance for leaders and developers in adopting engineering practices.
Technologies and stack
The consulting covers the ecosystem Wisalo already works with every day, including:
- Architecture Review
- Tech Due Diligence
- Code Audit
- Roadmap
- ADRs
- Clean Architecture
- AWS
- Kubernetes
How we work
Goal alignment
We understand the decision that needs to be made, the business context and the constraints.
Discovery
We analyze code, architecture, infrastructure and processes and interview the people involved.
Diagnosis
We consolidate findings with evidence, classified by severity and impact.
Recommendations
We present alternatives, trade-offs and a prioritized action plan.
Execution support
If it makes sense, we oversee or carry out the implementation together with your team.
Frequently asked questions
What is a technology assessment?
It is a structured evaluation of a system and how it is built and operated: architecture, code quality, infrastructure, security and delivery process. The result is an evidence-based diagnosis and a prioritized action plan.
Does the consulting include implementing the recommendations?
It can. Wisalo combines strategy and execution: you can hire only the diagnosis or also the support to implement the changes with our teams.
Do you do technical due diligence?
Yes. We assess the quality, risks and maintainability of a piece of software to support investment, acquisition or partnership decisions.
Is it better to rewrite the system from scratch?
In most cases, gradual modernization carries less risk than a complete rewrite, but the answer depends on the state of the system. We assess the case and present the alternatives with their risks.
How long does a consulting engagement last?
It depends on the scope and depth of the analysis. We define the scope and schedule in the proposal, after understanding the decision that needs to be made.
What do I receive at the end of the consulting engagement?
A diagnosis backed by evidence, risks classified by severity, recommendations with alternatives and trade-offs, a prioritized action plan and a record of architecture decisions, presented to your team.
