Work experience
Self Employed
Self-employed • 2 yrs 9 mos
Automation Specialist
Feb 2026 - Present • 8 mos
Self-employed automation specialist (Corfesto). I design and build business workflows inside the client's own n8n account so they keep the stack, keys, and hosting. Typical work since Feb 2026: linear and branching flows (CRM, Sheets/Airtable, email, Slack, WhatsApp/Telegram), lead scoring agents, FAQ/qualifier chatbots with calendar booking, and brand-monitoring setups with weekday email/Slack briefs. Scope per project is one process, not the whole company. I document the flow, error handling, and what to click if a node fails. Client provides n8n (Cloud or VPS), domains, LLM keys, and CRM seats. I do not host production as part of a basic build and I do not run captcha bypass or ToS-breaking scrapes. Deliverable is a working workflow in their account plus a short handover — not a forever retainer inside the same ticket.
Database Administrator
Sep 2024 - Present • 2 yrs 1 mo
Freelance database administrator for small product and operations teams, delivered through Corfesto. Design and document schemas (typically under 60 tables). Write, fix, and optimize SQL for reports and application logic. Review EXPLAIN plans, propose indexes, and leave a short note on what to measure after the change. Build query packs and lightweight reporting layers so the client can rerun the work without me. Prepare staging-safe migrations and cutover checklists; I do not apply unreviewed changes on production. Stack: PostgreSQL and MySQL, plus SQL Server when the client already has it. Deliverables are the SQL, a schema or ER note, and handover docs. Not 24/7 on-call DBA and not a compliance audit. This is the same scope I sell on Fiverr: one query, a query pack, or a small report layer — not “run the company’s entire database forever.”
Investigation Specialist Sr.
Amazon
Apr 2022 - May 2026 • 4 yrs 1 mo
Senior investigation specialist in Amazon marketplace operations (Costa Rica). Handled high-volume case queues covering suspicious buyer and seller activity, policy violations, and risk signals that affect customers and merchants. Pulled and reconciled data from internal tools and databases using Excel, SQL, and reporting extracts. Documented findings, recommended actions, and wrote clear case notes so decisions could be audited. Escalated edge cases and coordinated with internal teams and external parties by email. Tracked recurring patterns (abuse, policy gaps, repeat actors) and fed them into process and quality improvements instead of treating every ticket in isolation. Worked to SLAs in a shift-based environment with written standards and peer review.
