01
Distributed systems
Review service boundaries, data ownership, integration contracts and asynchronous workflows. Make failure modes, consistency requirements and operational trade-offs explicit before increasing system complexity.
Both Systems / Technical direction for business-critical software
Software Architecture Consulting
Make the next technical decision with a clear view of the trade-offs. Both Systems helps businesses assess existing systems, plan modernization and define architecture that fits their product, operating constraints and delivery capacity.

When the next decision carries real business risk
Growth, accumulated complexity and changing requirements can turn ordinary product work into difficult architectural decisions. An independent technical assessment helps separate the constraints that matter from the complexity you do not need to add.
- A growing product needs clearer service boundaries and ownership.
- A legacy platform is limiting change, but a wholesale rewrite is too risky.
- A new integration or distributed workflow raises reliability and consistency questions.
- A technical roadmap needs evidence before committing engineering time or budget.
/ Engagement scope
Architecture grounded in how your business operates
The engagement starts with your existing system and desired outcome—not a predetermined architecture or a preferred technology stack.
02
Incremental modernization
Identify seams in an existing platform and plan changes in manageable increments. Compare migration options, dependencies and rollback considerations without assuming that every legacy system needs a rewrite.
03
Technical assessments
Assess the relevant code, system documentation and operating context to identify maintainability concerns, technical risks and constraints. Prioritize findings according to business impact and the agreed scope.
04
Architecture guidance
Define system boundaries, document important decisions and evaluate alternatives with your engineering stakeholders. Turn architectural intent into a practical direction for implementation and review.
/ Potential deliverables
A decision you can explain. A next step you can act on.
Deliverables are agreed before work begins. Depending on the engagement, the work can include:
- A technical assessment with prioritized risks and findings.
- System diagrams and architecture decision records documenting alternatives and trade-offs.
- An incremental modernization roadmap with dependencies and review points.
- Working sessions and implementation guidance for the agreed architecture.
/ How the work happens
From context to an agreed technical direction
- 01
Frame the decision
Share the business goal, system context and constraints. Agree on the questions the engagement must answer.
- 02
Assess and compare
Review the relevant system and evaluate options against reliability, maintainability and delivery needs.
- 03
Define the next move
Document the recommendation, open questions and practical next steps. Agree on handover or further implementation support.
Direct access to the founder
Work directly with Marcelo Both, founder and senior engineer at Both Systems, with approximately 20 years of experience working with international clients. The person discussing your system is the person doing the work.
Engagements are scoped to one engineer’s capacity. Scope, deliverables and availability are agreed before work begins; ongoing support is not an automatic commitment.

What architecture decision is holding you back?
Share your system context, the decision you need to make and any delivery constraints. The first conversation establishes whether a focused assessment or a longer advisory engagement is the right fit.
