Built on Aviation Principles: Precision, Reliability, Speed.
Vector 9 Software is a bespoke systems engineering studio, distributed systems laboratory, and corporate parent behind specialized practices.
The Intersection of Frontline Aviation and Systems Architecture
"We reject software bloat, unnecessary latency, and fragile cloud dependencies. High-consequence operations demand software that works with absolute certainty."
— Vector 9 Software Engineering DoctrineVector 9 Software was founded on a singular realization: whether in a fighter cockpit executing a tactical sortie or on an enterprise operations desk coordinating global inventory, operational friction is the root cause of systemic failure.
Headquartered in the Leiria region of Portugal—adjacent to Monte Real Air Base (BA5)—we pair frontline fighter aviators with veteran distributed systems engineers with over 15 years of high-consequence platform experience.
As the parent entity, Vector 9 Software oversees sovereign data infrastructure, distributed database research, and bilateral enterprise contracting, while deploying specialized operational software through our dedicated practices.
Aviators & Systems Architects
Frontline fighter aviators working alongside senior distributed systems engineers.
Pedro Leal
Head of FlightSQN
Operational fighter pilot with experience in daily sortie planning, standardization and evaluation, and squadron operational execution.
Marco Silva
Lead Project Manager
Over 15 years leading enterprise engineering and mission-critical software initiatives. Oversees agile product delivery and defense-compliant architectures.
João Rodrigues
Lead Software Engineer
Specializes in high-performance local-first distributed systems, air-gapped cryptographic security protocols, and real-time operational state synchronization.
Strategic Foundations
Three core engineering pillars that guide every platform we build.
Fighter Aviation Rigor
Founded and guided by active fighter pilots. We design operational systems with the same uncompromising discipline, ergonomics, and fault tolerance demanded in combat aviation.
Sovereign & Local-First R&D
Complete data sovereignty, host-resident databases, and cryptographic resilience. Across internal tools and client platforms, data is stored directly on a private VPS or local machine.
Dual-Vertical Delivery
Operating two dedicated engineering practices: FlightSQN for specialized aviation and defense, and V9 Enterprise for custom enterprise platforms, ERPs, and high-throughput commercial operations.
Sovereign European Base
Vector 9 Software is incorporated and operates in the Leiria region of Portugal, adjacent to Monte Real Air Base (BA5). Operating under strict Portuguese and European Union sovereign legal jurisdiction.
Full compliance with EU GDPR data sovereignty, defense confidentiality guidelines, and bilateral Master Services Agreements.
