Your growth outgrew your systems.
That is why everything feels manual: data scattered across tools that do not talk, reports built by hand, automations that break when you need them most. It is not a people problem. It is technology acting as a bottleneck instead of the pillar your growth stands on. And that is fixable.
If you are reading this, you are probably not looking for a pair of hands. You already see the version of your company that runs like a machine: you have it built in your head, down to the dashboards. What you have not found is someone who can build it at the level you imagine it. You take your operation seriously, you move fast, and you know that owning everything is not the same as doing it all yourself. That is exactly who I do my best work with.
That is where I come in. You could call me a systems architect, but the title falls short: I am the person you hand a problem to and stop thinking about it. From the first conversation to the system running in production, the whole path is mine to own. I will not spend this paragraph convincing you; the profile you are reading already does that. The standard you have in your head is the one I work at.

• Full-stack platforms: React, TypeScript, Supabase, PostgreSQL, AWS
• AI agents that carry real workloads: chat, voice, decision logic
• Integrations across CRM, finance, and operations, working as one system
• The architecture and technical direction that tie it all together

• You work directly with me: I lead Prometio Group, and I am the one who runs discovery, designs the architecture, and writes the code
• Every delivery includes tests, documentation, and a handover another engineer could pick up tomorrow
• You own everything: your GitHub, your accounts, your infrastructure
• Full US time zone overlap, clear communication every day

The best systems are built on three things, and they run in both directions:
• Honesty: I tell you the truth about progress, problems, and costs the day I see them. I expect the same about your priorities and constraints.
• Hard work: I hold a high bar for what ships. You bring the same seriousness to your side of the table.
• Responsibility: I own my outcomes and my mistakes. You own your decisions, on time.
If that is not how you work, we are not a match, and that is fine. If it is, send me a short description of what you are building. I will tell you honestly whether I am the right fit, and who is if I am not.
