Capabilities

What we do

Two decades across software development and cybersecurity, from internet‑scale infrastructure to one‑machine automations that quietly run a business.

01 · build

Custom software

Web apps, internal tools, data pipelines and APIs. Built lean, documented, and handed over in a state you can actually maintain.

02 · secure

Security & hardening

Audits, infrastructure lockdown, DNS and email authentication (SPF, DKIM, DMARC), and incident cleanup. We think like the attacker because we've studied them for years.

03 · automate

Automation & AI agents

Self‑hosted AI gateways, monitoring bots, scrapers and scheduled workflows that replace the boring 80% of operational work.

04 · ship

Web & infrastructure

Static and dynamic sites on AWS and Cloudflare, performance tuning, analytics, and deployment pipelines that make publishing a one‑line command.

05 · model

Data & modeling

Statistical models, prediction systems and live data feeds. Sports, markets, weather: whatever the signal is, we build the pipeline that catches it.

06 · rescue

Rescue missions

Inherited a mess? Stalled project, dead vendor, mystery server? We walk into unfamiliar systems and get them back under control.

07 · apps

iPhone, iPad & Watch apps

Native Swift apps with widgets, complications, Siri and Shortcuts. Dashboard for Ecowitt is ours; yours could be next.

Who we are
