What I'm looking for

Seeking an autonomous QA Automation or Tech Ops role focused on building scalable CI/CD testing pipelines, backend API validation, and data infrastructure testing. I prioritize high-impact, asynchronous execution over synchronous overhead, specializing in Playwright, Python, and AWS environments

About
PORTFOLIO: https://martindao.onrender.com

Technical Product Operations & QA Automation Architect | Escalation Engineer

I bridge the gap between complex product logic and technical infrastructure. I don't just find bugs; I architect the automated frameworks to prevent them and lead the Tier 3 escalation efforts to resolve them when they hit production.

With 8+ years across Microsoft, FPT, and high-growth AI startups, I specialize in "Resilient Product Delivery"—ensuring high-velocity releases without sacrificing system stability.

Technical Core:

Automation Strategy: Architected end-to-end Playwright and Cypress frameworks from scratch, cutting regression cycles by 60% and reducing flake by 75%.

Technical Operations: Expert in production triage using Datadog, Kubernetes, and Splunk. I specialize in Root Cause Analysis (RCA) and reducing Mean Time to Resolution (MTTR) for P1 incidents.

Data Validation: Advanced SQL & Python expert. I build automated data validation scripts to ensure 99.9% accuracy across high-volume ERP and MarTech pipelines.

Release Coordination: Expert at bridging the "Dev-to-Prod" gap. I lead the triage, severity assignment, and developer handoff to keep release cycles on track.

My Toolkit:

Test Automation: Playwright, Cypress, Selenium, Pytest, API Testing (Postman/GraphQL)

Infrastructure & Ops: AWS, Kubernetes, Docker, GitHub Actions, Jenkins, CI/CD

Observability: Datadog, Grafana, Splunk, New Relic, Sentry, ELK Stack

Business Logic: SDLC, Agile/Scrum, Jira/ServiceNow, SQL (Advanced), Python (Pandas)

I am a builder who understands the business case behind every line of code. If your team needs a technical mercenary to stabilize your automation, triage your production fire drills, or optimize your release operations, let’s connect
