I started in a classified environment writing war game simulations. Now I build compliance-grade iOS software alone. The standards never changed. The bureaucracy did.

Teachers spend 40 minutes after every incident on paperwork that never reaches the right person. Bitácora closes that loop in the moment, on device, in both languages. FERPA. LFPDPPP. No district server touched.

Bitácora

Solo Founder · iOS Engineer

Teachers log observations, flag incidents, and see patterns. No paperwork. I built it alone: concept, architecture, compliance, App Store submission.

  • Bilingual from day one. EN/ES is first-class, not an afterthought.
  • On-device AI. Zero student data leaves the device.
  • Architected for two-country compliance: FERPA (US) and LFPDPPP (Mexico).
  • SwiftData persistence with encrypted sync, privacy by design.

SRE & Infrastructure

Systems Reliability Engineering

Years keeping production systems alive. When things break at 2am, I've been the one in the terminal. At Electric AI, one migration quarter delivered a 50% productivity gain. The runbooks are still running. That experience is now structural in how I build.

  • Cloud infrastructure design and cost optimization.
  • Incident response and post-mortem culture.
  • CI/CD pipelines, containerization, observability.

Bitácora Dashboard

Solo Founder · Full-Stack Engineer

My internal ops center. Real-time visibility across tickets, QA, AI costs, and agent workflows. I built it because I needed it. It's not a demo.

  • AI-powered ticket generation with Claude. Structured outputs with compliance flags and effort estimates.
  • QA test case tracker with CSV import, filtering, and one-click YouTrack bug creation.
  • AI usage and cost monitoring across Anthropic and OpenAI, with budget alerts.
  • Session-based auth with AES-256-GCM encrypted credential storage. API keys never reach the browser.

See how credential storage works
// AES-256-GCM — API tokens encrypted at rest in SQLite. // Student data never reaches the browser. export function encrypt(plaintext) { const key = getKey(); const iv = randomBytes(12); // 96-bit IV for GCM const cipher = createCipheriv('aes-256-gcm', key, iv); let encrypted = cipher.update(plaintext, 'utf8', 'hex'); encrypted += cipher.final('hex'); return { encrypted, iv: iv.toString('hex'), tag: cipher.getAuthTag().toString('hex'), }; }

System Architecture

Capabilities

iOS / Swift SwiftUI, SwiftData, CoreML, HealthKit, CloudKit. Production apps that live on real devices.
Bilingual Product EN/ES as a first-class constraint, not a translation layer. I've shipped bilingual products at every layer of the stack.
AI Integration On-device AI via CoreML, API integration with OpenAI/Anthropic, agent-assisted development workflows.
Compliance FERPA and LFPDPPP in production. Not as add-ons. I architect data flows so the constraints are load-bearing, not bolted on after the fact.
Infrastructure & SRE AWS, Docker, Kubernetes, Terraform. Incident response at scale. Systems built to stay up.
Full-Stack Web React, Node.js, SQLite. Internal tooling and dashboards for the Bitácora platform.
Engineering Mentorship QA engineering instructor at TripleTen. I teach the way I onboarded SRE teams. Socratic method. I don't hand you the answer. I surface the question that makes it obvious.

How I Build

01
Clarity first Before any code, I define the problem precisely. Wrong problem, wrong solution.
02
Agent-assisted build 8 agents, each scoped to one domain: iOS, backend, QA, security, compliance. I define the problem, review the output, and make every architectural call.
03
Test on device Every feature gets tested on hardware, not just the simulator. Real behavior matters.
04
Ship with intent Versioned releases, meaningful changelogs, compliance sign-off. Nothing goes out without purpose.
The edge

Solo engineer. No stand-ups. No handoffs. No one waiting on someone else's review. I hold the full context. Architecture, compliance, product. I've held that kind of ownership since White Sands. Decisions get made in the same sitting.

About

Mr. Primo
Mr. Primo Reads Zarathustra. Ships iOS apps. Both make sense.

I wrote Java for war games simulations at White Sands Missile Range. Containerized classified systems for a defense contractor. Kept production alive as an SRE at a VC-backed startup in New York. Built performance pipelines for a telehealth platform in San Diego. Now I build Bitácora, an iOS app for teachers, solo. The reliability bar is the same. The person accountable for everything is still one.

I run the full stack myself. iOS development, VPS infrastructure, agent orchestration, compliance architecture. There is no backend team. There is no ops team. One system. One vision. Every decision mine.

50% productivity gain, Electric AI migration
FERPA + LFPDPPP. Two-country student data compliance, production.
0 data breaches. Student data stays on device.

Since we started using Bitácora, incident documentation that used to take me half an hour now takes five minutes. And I know it actually gets read.
