Solid bases.
Big achievements.
We transform enterprise complexity into robust, fast, and scalable digital solutions. We elevate OutSystems ecosystems to the highest standards of software engineering with direct senior mentorship.
How Was Base64 Born?
The OutSystems platform revolutionized enterprise software development worldwide. However, its own rapid success created a critical market challenge.
The Market Challenge
Rapid market expansion coupled with the platform's abstraction layer led to many developers lacking deep knowledge of its inner workings and the context of complex, interconnected enterprise ecosystems.
Our Motivation
We founded Base64 to bridge the experience gap the market faces today. We provide clients with genuinely seasoned senior consultants capable of leading projects with precision and architectural rigor.
Sustained Growth
Our junior developers are personally trained by the partners themselves. For their first six months, they work alongside senior engineers, ensuring absolute alignment with our core engineering values and technical excellence.
Software Architecture Without Shortcuts.
We don't just build 'fast screens'. We deliver rock-solid digital foundations engineered to handle millions of transactions, continuous integration, and seamless long-term evolution.
Direct Partner Mentorship
Continuous hands-on senior technical supervision across all projects by architects who have mastered the platform since its inception.
Engineering Beyond Low-Code
Deep proficiency in C#, native .NET extensions, high-throughput relational database architectures, and responsive UI design systems.
Focus on Governance and Scalability
Strict implementation of the 4-Layer Architecture (4LA) framework, eliminating cyclic dependencies and preventing future bottlenecks.

Frequently Asked Questions About Our Services
Transparent answers regarding our software architecture methodology, ODC/O11 platforms, and team mentorship.
What distinguishes Base64 from other OutSystems consulting firms?
Base64 was founded to bridge the 'experience gap' in the OutSystems ecosystem. Our junior developers are trained and mentored directly by the founding partners for at least six months on real projects. Furthermore, we master deep software engineering beyond low-code, including C#, .NET, high-throughput relational databases, and strict 4LA architectural governance.
Does Base64 have experience with OutSystems Developer Cloud (ODC) and OutSystems 11?
Yes. Our team holds extensive experience and certifications in OutSystems 11 as well as the latest OutSystems Developer Cloud (ODC) platform, designing cloud-native modular solutions prepared for microservices.
How does the architecture audit and code health check work?
We thoroughly audit your software factory against the Architecture Canvas (4LA), identifying cyclic dependencies, slow database queries, security risks, and best practice violations, delivering an actionable executive report for technical debt elimination.
Can Base64 provide dedicated squads or mentor our internal team?
Yes. We supply high-performing complete squads or allocate senior tech leads for hands-on coaching, elevating your internal team's technical maturity and accelerating critical deliveries.
Where is Base64 located and where do you deliver services?
Base64 Solutions is headquartered in Lisbon at Avenida da República, Nº 6, 7º Esq, 1050-191 Lisbon, Portugal. We operate both on-site and remotely for clients in Portugal and across international markets.
