Experience

Founder

LogSworn · Canada · Sep 2026 – Present

Founded a Canadian engineering company building tamper-evident sensor records for buildings: LoRaWAN sensors, hubs that sign every batch of readings, and a client web app with reports an inspector can verify independently.
Offers engineering services in cloud, data and AI, software, and connected devices.

Site Reliability Engineer

Global SaaS platform · Remote · Sep 2023 – Oct 2026

Built an event-driven service and VM recovery system on Google Cloud in Python: ticket webhooks trigger GitLab CI/CD pipelines, an AI-assisted triage step decides what to act on, and services restart automatically. Cut time-to-recovery from ~25 minutes to ~5.
Wrote Python and Bash automation for server management, diagnostics and load measurement across a ~2,000-server global production environment.
Converted hundreds of recurring manual ticket processes into one-click runbooks, and authored and maintained the runbooks and operational documentation.
Built or contributed to 30–50 internal dashboards, reports and ETL pipelines on GCP, BigQuery and Superset.
Proposed and delivered the integration of Google Gemini into engineering and support workflows, roughly doubling throughput on recurring ticket work.
Senior technical point of contact for production issues: live debugging and performance tuning in containerized Kubernetes services, and architecture and scaling recommendations for technical and non-technical stakeholders.

Senior Technical Support and Application Developer

Global SaaS platform · Remote · Jul 2022 – Sep 2023

Led a team of 3 maintainers owning assignment and productivity tooling, consistently delivering within SLA.
Wrote and pitched the technical proposal for a case-routing platform, then built it on React, Express/Node.js and PostgreSQL on GCP. It routes 100–200 support cases a day across ~40 agents worldwide by skill, language and region.
Built internal web apps and REST APIs, and developed and customized Salesforce applications for customer-specific requirements.

Technical Support Specialist, Bilingual

Global SaaS platform · Remote · Jan 2021 – Jul 2022

Resolved 9–10 senior-tier enterprise tickets a day at ~95% SLA adherence and over 90% QA scores.
Subject-matter expert on SDK and REST API integrations for enterprise customers.
KCS Knowledge Domain Expert: authored or curated 60+ knowledge-base articles.
English and Spanish support for Latin American accounts; turned complex issues into actionable defect reports for engineering.

Web Developer (freelance)

European technology startup · Remote · Dec 2019 – Mar 2020

Built responsive web and desktop applications in PHP, from requirements through deployment.

Systems Analyst

Retail bank · Aug 2018 – Nov 2019

Developed and deployed secure internet-banking systems in Java, and mobile banking features with Ionic.
Designed a UID-generation algorithm (Java, IBM Informix) producing traceable, non-sequential identifiers for flagged batch transactions.

Server Administrator

Cloud technology startup · Remote · Jul 2017 – Nov 2017

Set up and administered the founding database and web-server infrastructure.

Projects

vagrantNet (open source, github.com/aadiaz1804/vagrantNet): publishing protocol and TUI client for LoRa mesh radio networks, built for sub-kilobyte bandwidth. A custom zstd dictionary gives 45% smaller payloads and 34% fewer round trips than plain zstd over 500 randomized pages. Runs under systemd, deployed with Docker.
High-concurrency network telemetry engine: asynchronous Python (asyncio) engine polling thousands of servers from a single Linux node and aggregating sub-minute response times into latency profiles.
Homelab: Unraid, Proxmox and Kubernetes running personal services, with Portainer and Tailscale.
Clinic management system: Laravel/PHP application for clinic, patient and pharmacy operations at low-income clinics in Latin America.
