Engineering for what's
already in production.

The identity
behind the code
H2V Systems is led by Hiury Vilanova — hands-on engineering when traffic grows, legacy gets in the way, or a new product needs a real ship date.
The H2 and V come from the founder's name: an owner for the project, short communication, and technical calls explained without marketing gloss.
Mission
Reduce incidents and rework with software you can actually run — readable logs, predictable deploys, scope we honor.
Vision
Be the team you call when you need someone who read the stack trace and suggests the next step without pushing an endless rewrite.
Values
Say no when the timeline doesn't work, write down what we agreed, and keep email/Slack/WhatsApp answered during business hours.
// H2V Systems — Core Philosophy const h2v = { founder: 'Hiury Vilanova', mission: 'Build digital foundations', stack: [ 'Java', 'Kotlin', 'Spring', 'React', 'Node', 'AWS', 'Cloud' ], values: [ 'transparency', 'excellence', 'client_success', ], deliver(project) { return project .plan().build() .test().deploy('production'); } }; // Powering digital foundations
// Founded by
Hiury Vilanova. Software engineer with a track record in Java/Kotlin/Spring, React, and environments where incidents are expensive — usually leads technical discovery and PR review.
From briefing to deploy
Clarity on what ships each sprint — you see delivery, not just phase promises.
Discovery
We dive deep into your business. We understand the real problem, stakeholders and define the scope with precision.
Architecture
We design the ideal solution. Stack, infrastructure, database and APIs, all documented and validated before we write a single line of code.
Development
Agile sprints with incremental deliveries. Code review, automated testing and continuous deployment.
Sustainability
24/7 monitoring, security updates and technical support so the system evolves alongside you.
What people say about our work
Feedback from people who worked with us on critical work — generic titles because of NDAs.
We had pain in queues and reporting; within two weeks we were measuring again. Architecture explained without theater.
We cut processing time a lot after they drew the right flow — without selling a universe-sized refactor.
Deadlines met, PRs with context, tests where it mattered. Recommend for teams with no patience for slides.
