Dan Ochoa

Software developer, architect & project manager in the AI era.

Full-time at Coral Vita, writing C#, .NET and PostgreSQL. After hours I architect and ship indie products end-to-end — Cronradar, HumanProof, Ashbase, NeuroEval and more.

紹介

One foot in the codebase, one in the roadmap.

I'm Dan — a CS grad from Universidad Tecnológica de México, based in Greater Orlando. Full-time Software Developer at Coral Vita, and on the side I architect and ship a small portfolio of indie products.
i.

Develop

C#, .NET, ASP.NET and PostgreSQL by day at Coral Vita. TypeScript, Next.js and Avalonia anywhere a fast UI is needed.

ii.

Architect

End-to-end systems — multi-language SDKs, monorepos, container orchestration, and CMS-driven sites that survive contact with real traffic.

iii.

Manage

Years of running scope, stakeholders and timelines as a founder, PM and full-stack engineer. Comfortable owning the awkward conversations.

iv.

Leverage AI

Ship LLM-native features — see Crontab Space's natural-language → cron — and use modern AI tooling daily to compound output.

Things I've built and shipped.

A handful of products from the last few years — most solo, all in production or actively developed.

Cronradar

Drop-in cron monitoring for .NET, Node, Python, PHP and more.

A self-hostable .NET 9 / Aspire server, a CMS-driven marketing site, and nine SDKs covering the runtimes I keep running into in production. The 2023 serverless prototype became this.

    Research

    HumanProof

    An assessment for the AI era of cognitive work.

    An assessment that scores whether a person can do valuable cognitive work in collaboration with AI — not their prompting skill, not their AI knowledge. Companies pay per candidate or for L&D programs; a free tier exists for self-assessment. Pairs with Shinsotsu as the measurement half of the loop.

    Shinsotsu

    A hiring platform where candidates and companies both come out ahead.

    A hiring platform built so both sides win. Companies submit a role and receive three HumanProof-tested candidates with a commitment to interview all of them. Candidates skip the résumé pile and the ghosting — every introduction is to a company that’s already in. The distribution half of the HumanProof × Shinsotsu loop.

    Ashbase

    GDPR-clean deletes for production Postgres.

    A PostgreSQL extension that makes DELETE destroy personal columns instead of rows — analytics keep working, the row stays joinable, and every transition writes a hash-chained audit entry an auditor can verify without trusting you. Open-source extension + paid cloud companion.

    NeuroEval

    Developmental screening, online and end-to-end.

    Spanish-first online instrument that automates a manual neurodevelopment evaluation. Caregivers answer age-banded questions across five areas; the engine scores them, flags delays, and surfaces compensatory activities. AI narrates the rule-based engine's output without inventing recommendations. Admin panel is private.

    Crontab Space

    Read, write and debug cron — with AI.

    A free tool to read, write and debug cron expressions. Includes an LLM-powered natural-language → cron generator, a visual builder, and a syntax reference.

    Inferno CMS

    An open-source headless CMS that gets out of the way.

    Open-source, npm-installable headless CMS. Content modeling, webhooks, timestamps, and a quiet monochrome admin UI. Distributed as a pnpm monorepo.

実験

What I've explored, killed, and learned from.

A short list of products that taught me something real before I shut them down or rebuilt them.
  • 2023 — 2024
    Halfnine.com

    My solo B2B software studio (2023–2024). Marketing site, sales funnel and client delivery, all owned end-to-end. The site reached real traffic and the studio had paying clients.

    Wound it down when I took the Coral Vita role. The studio paid its own way and ended cleanly — no clients left mid-project.

  • Nov — Dec 2023
    yourname.is

    A niche SaaS for personalized first@last.com email — branding, auth, billing, infra, all solo. Real customers paying real money.

    Validated I could run a niche SaaS end-to-end alone. Closed because the niche stayed niche; the playbook stayed.

  • Apr — Nov 2023
    surveyr.io

    Acquired a UK-based Laravel job-monitoring SaaS, migrated it to US infrastructure, and operated it for 7 months as PM + full-stack engineer.

    First time taking over an inherited codebase and live customer base. Migration shipped without losing a row or a customer.

  • 2023
    serverless-cron-monitor

    First attempt at a cron monitoring service, built serverless.

    Self-labeled “Bad — Ignore.” Cold starts and serverless quotas killed the value prop. The lesson became Cronradar — a long-running, self-hostable .NET server with proper SDKs.

  • 2022
    QuoteBid (“OpenContracts”)

    Marketplace prototype for contract bidding (“OpenContracts”), 2022.

    First contact with marketplace dynamics. Two-sided liquidity is brutal as a solo dev — better suited for products with single-sided demand.

  • 2022
    Excalibur (xc-architecture)

    Architecture notes for a sensor system, codename “Excalibur,” 2022.

    Pre-code architecture writing as a discipline. That habit is now baked into how I plan Cronradar and Inferno.

道具

The stack I reach for when the brief says “ship it.”

.NET on the server when the team needs it, TypeScript everywhere else, AI tooling woven throughout. Pragmatic choices, modern defaults.
