Solo Founder & Software Engineer

Building tools educators actually want to use.

I build Bitacora — an iOS app that helps teachers track student observations and behavioral patterns. Designed for schools in the US and Mexico. Compliant. Private. Fast.

Built from scratch. Shipped to production.

Bitacora

Solo Founder · iOS Engineer

App Store

An iOS app that helps teachers log student observations, flag behavioral incidents, and surface patterns — without paperwork slowing them down. Built solo, from concept to App Store.

  • Bilingual from day one — EN/ES first-class, not an afterthought.
  • On-device AI inference — 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 of keeping systems alive at scale. Cloud architecture, incident response, and the discipline that makes software reliable by design.

Capabilities

What I bring to your project.

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 inference via CoreML, API integration with OpenAI/Anthropic, agent-assisted development workflows.

Compliance

FERPA and LFPDPPP in production. I architect data flows so compliance is structural, not a checkbox.

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 Bitacora platform.

How I Build

Agent-assisted. Shipping-focused.

I've built an AI agent workflow that compresses solo development timelines without cutting corners on quality.

Clarity first

Before any code, I define the problem precisely. Wrong problem, wrong solution.

Agent-assisted build

I run a team of specialized AI agents — iOS, backend, QA, security — each scoped to a domain. I direct and review.

iOS Backend QA Security

Test on device

Every feature gets tested on hardware — not just the simulator. Real behavior matters.

Ship with intent

Versioned releases, meaningful changelogs, compliance sign-off. Nothing goes out without purpose.

The edge

Solo engineer. Zero bureaucracy. Fast decisions. Deep context on the problem. I can ship what a team takes months to build.

About

Mr. Primo

Curious by nature. Shipping by habit.

Mr. Primo is a solo founder and software engineer focused on the intersection of education and technology. I build Bitacora — an observation and incident-tracking app for teachers — because the best tools come from understanding the tedium firsthand.

I work across the full stack: iOS, cloud infrastructure, and the systems that keep products running at scale. When I'm not shipping features, I'm thinking about the next problem worth solving.

Let's build something.

I take on a limited number of consulting engagements alongside Bitacora development. If you're building something in EdTech — or need someone who understands bilingual product from the ground up — let's talk.
