Customer support specialist moving toward technical investigation work: L2/L3 support, application support, and SQL/data-driven troubleshooting.

I currently work as a Senior Customer Support Specialist at a B2B SaaS company building document scanning and PMS integrations for the hospitality industry. Before that I spent close to two decades running my own ventures, including building and operating a high-traffic e-commerce marketplace with hands-on API integration, database management, and web scraping work.

I'm not a software engineer and I don't want to be one. What I'm good at is taking a vague or broken customer report and turning it into a concrete, evidence-backed answer: what happened, why it happened, and what the data actually shows. This profile is where I practice and document that kind of investigative work.

• Building a portfolio of technical investigation write-ups using real tools (Postman, SQL, Kibana) against realistic scenarios
• Working through SQL fundamentals and query-based problem solving from first principles
• Learning to read logs and API behavior the way a support engineer needs to, not the way a developer does

Postman API Investigation Investigated a mock API for silent field acceptance, authentication enforcement gaps, and rate-limiting exposure. Framed as a real-world triage case: what a customer would report, what the API actually does, and what the fix should be.

SQL Investigation: PMS Booking Sync A synthetic property-management-system booking-sync scenario used to practice root cause analysis through SQL queries alone, no assumptions, no guessing, just what the data shows.

Kibana Log Analysis Time-series spike detection and anomaly investigation using log data, focused on identifying what changed and when.

SQL Cheat Sheet A working reference I built while learning: query execution order, NULL handling, JOIN types, aggregations, HAVING vs WHERE, subqueries, and style conventions.
