About // 01

Building systems that endure.

I work at the intersection of deep engineering and strategic execution. From system architecture to production operations, with a constant focus on continuity and stability.

Design and evolution of distributed systems with emphasis on integration and observability, in environments where operational continuity and technical consistency are fundamental.

Systems thinking

Designing from first principles, considering the complete lifecycle of every system.

Built-in resilience

Architectures conceived to sustain operations continuously and predictably.

Technical execution

Implementation aligned with strategic objectives, focused on consistent results in production.

What I Build // 02

I design systems and build the products that prove them.

I founded and lead an engineering studio: from concept and architecture to products running in production.

Engineering studio In production

Del Portal Technologies

My studio. It designs, builds and operates its own high-availability digital products. I lead the architecture and execution.

iOS · Android · Web
Fitness Functional

TrainO System

Born from my own injury and designed as a system: instead of handing out templates, it reasons and adapts every session to your real recovery.

iOS · Android
PropTech Functional

Inquora

Building and community administration. An app in production under the same architectural rigor as a critical system.

iOS · Android · PWA
FinTech Functional

Zent

Personal and business finance, with a shared mode. Designed as a system, not a pile of screens.

iOS · Android · PWA
macOS · Security · Local AI Functional

VaultOS

A local-first knowledge vault for Mac. Layered encryption (AES-256-GCM, Argon2id, Touch ID) and on-device local AI. No cloud, no telemetry.

Electron · React · TypeScript
Game engine · In development

BabelDestiny

A data-driven engine for an isometric Action Roguelite. Documented spec-first: every contract written before the first line of code.

Latency diagnosis in distributed systems

Integration platform · IBM Sterling

Intermittent latency without clear traceability caused SLA breach.
Custom observability stack enabled root cause identification in minutes.
Architecture

Microservices migration

Monolithic system · Financial sector

Unsustainable monolith blocked deployments and independent scaling.

Manifesto // 07

"The system doesn't interpret; it executes."

— Jorel del Portal

Everything else is a consequence.
