I craft products that are real-time

Full-stack engineer specializing in Elixir & Phoenix. Currently building multi-tenant IoT and security platforms at Blacksight — real-time monitoring, honeypots, and compliance-grade reporting (CMMC 2.0, FIPS 140-3) — shipped end to end.

Where I've made an impact

Software Engineer @Blacksight LLC

Nov 2025 — Present

Building multi-tenant IoT & security platforms — real-time, compliance-grade, shipped end to end.

  • Built a multi-tenant IoT device management platform (Protect) using Phoenix/Elixir with customer, partner, GSOC, and admin portals, real-time monitoring, alarm management, and compliance reporting (CMMC 2.0, FIPS 140-3, NDAA).
  • Contributed to a distributed honeypot security system that simulates 15+ network services to detect unauthorized access, with real-time attack reporting and OTP-based fault tolerance.
  • Created a DNS/port scanning service (Scanner) with affiliate management, Stripe integration, subscription handling, and automated scanning workers for DNS, port, and scheduled scans.
  • Maintained the company marketing website (www) using Phoenix/Elixir with contact forms, career pages, and platform integrations for lead generation.

Playgrounds

I learn systems by rebuilding them as visual machines. Here's the BEAM — Elixir's VM — running lightweight processes and passing messages, live.

3worker = spawn(fn ->
4  receive do
5    {:ping, from} -> send(from, :pong)

parent = self() — capture the running process's pid.

BEAM Message Passing

Step through spawn, send and receive across process mailboxes.

LIVE

Supervision Trees & Restarts

Crash a child and watch the supervisor apply its restart strategy.

NEXT

Phoenix LiveView Lifecycle

mount → render → handle_event → diff over the WebSocket.

SOON

React Render & Commit

Render phase, reconciliation, and the commit to the DOM.

SOON

Angular Change Detection

Zone.js, the component tree, and OnPush vs default.

Answer

What kind of projects do you take on as a freelancer?

I build full-stack web applications end to end — real-time platforms, multi-tenant SaaS, dashboards, internal tools, and marketing sites. My sweet spot is Elixir/Phoenix on the backend (LiveView, OTP, PostgreSQL) paired with React or Next.js on the front-end, but I'm comfortable owning the whole stack including deployment.
