About Me

Rio Fenris — black-backed jackal

local-first, unapologetic QA, and systems that don’t break at 3 AM

I’m Rio. Born in Russia, rebooted life in the U.S. in 2024. I build local-only smart home systems, design resilient infrastructure, and apply ruthless QA mindset to everything from code to human processes. If it’s flaky, I’ll make it boringly reliable. If it’s over-engineered, I’ll trim it to the bone.

TL;DR value prop

  • Local-first architecture: lighting, HVAC, security, bots — all under your control, not someone’s cloud bill.
  • Operational rigor: logging, deduping, edge-case coverage, and failure paths that fail safe.
  • Delivery over theater: ship MVP → harden to MMF → iterate. Less slideware, more uptime.

Core competencies

  • Systems & Networks: Windows Server/AD, SMB, routing/VPN, monitoring, CCTV.
  • Security & Hardening: least-privilege, segmented networks, practical threat modeling for homes & small biz.
  • QA / SDET mode: test design, reproducible bug hunts, flaky-killer, log/metrics hygiene, “no duplicate triggers.”
  • Automation: Home Assistant, Telegram Bot API, event-driven scripts, scheduled jobs, templating.
  • Dev & Scripting: YAML, Python (utility scripts), Bash, HTML/CSS/JS for internal tools.

Selected wins

  • Coyotes Vision: privacy-first automations with Tomorrow.io weather, dynamic Telegram bot voice, “Total Silence” DND, camera snapshot & on-demand clip send, randomized replies, and sane logging. Designed for humans, not just nerds.
  • Route Killer (workplace utility): lightweight web tool to convert route codes ⇄ floor locations with history, multi-input, unique-count logic, autoscroll UX, mobile-friendly layout, and keyboard-first flow. Reduced mental overhead on the floor; currently iterating toward formal tooling standards. Made for biggest Amazon SSD in US (SOR3).
  • Local media delivery: explored VLC remote and Snapcast patterns for reliable sound prompts without cloud dependencies; pragmatic fallback when Bluetooth devices nap.

Projects

  • Coyotes Vision — friendly, opinionated smart-home stack with a mascot, humor, and ruthless reliability under the hood.
  • Route Killer — internal-style tool for route/floor conversion with UX that doesn’t fight you.
  • Full Effect — hand-crafting a custom “2.5-GO fuckyouself” engine because existing ones felt too slow
  • Escapism Project: never meant to be a doom mod.

Experience snapshot

10+ years across sysadmin, networking, infosec, CCTV, and team lead roles. Currently at the biggest Amazon SSD (problem solve squad) while building tools that make frontline work suck less.

Tech I speak (daily driver set)

  • Infra: Windows Server/AD, SMB, VLANs, static routing, WireGuard, Nginx, basic Docker.
  • Automation: Home Assistant, Jinja2 templating, Telegram Bot API, cron/scheduled jobs.
  • Tooling: VLC remote, Snapcast basics, qBittorrent API, simple REST/webhooks.
  • Stack: YAML, Python, Bash, HTML/CSS/JS; Git when it actually helps.

What I’m open to

  • QA / SDET (manual + light automation): test design, flaky eradication, observability, CI-friendly reporting.
  • Systems / IT / SecOps (hands-on): local-first deployments, network hardening, CCTV, practical monitoring.
  • Smart-home consulting: human-centric installs that don’t depend on three clouds and a prayer.
  • Internal tools: quick MVPs that remove toil and reduce training time for frontline teams.

Location: Portland, OR (open to remote and Pacific-time engagements). LinkedIn has the formalities; this page has the truth.

I don’t bite. Mostly.
