// H2V Systems — Core Philosophy const h2v = { founder: 'Hiury Vilanova', mission: 'Build digital foundations', stack: [ 'Java', 'Kotlin', 'Spring', 'React', 'Node', 'AWS' ], values: [ 'transparency', 'excellence' ], deliver(project) { return project .plan().build() .test().deploy('production'); } };
// Founder
Hiury Vilanova Software architecture specialist with an extensive technical background in JVM ecosystems (Java/Kotlin), React, distributed messaging (Kafka), and mission-critical hybrid cloud environments.
From first contact to long-term partnership.
A clear, transparent, and result-oriented process structured in four stages.
Immersion & Alignment
We dive into the business ecosystem to map data flows, technical bottlenecks, and prioritized scope.
Solution Design
Data modeling, systems architecture, API definitions, and security plans approved before writing a single line of code.
Iterative Development
Incremental delivery by sprints, with strict code review processes, test automation, and continuous security.
DevOps & Evolution
24/7 proactive monitoring, complete telemetry, cloud cost optimization, and specialized technical support.
Results certified by clients
What technology partners say about our critical deliveries (pseudonyms applied under NDA).
We had severe performance issues in our processing queues. H2V diagnosed and resolved them with precision in two weeks.
The architecture consulting reduced our cloud computing operational costs by more than 60% without compromising system stability.
On-time deliveries, absolute transparency in pull requests, and highly maintainable code. Highly recommended.
