About

Professional summary

I am a Technical Support and Integrations Engineer with more than three years of hands-on experience in L1/L2 support, B2B client integrations, API diagnostics, and data verification. I have also spent two years in operations management, coordinating client-facing workflows and maintaining service quality.

I manage end-to-end integrations, from requirements gathering and data scoping to feed configuration, testing, production rollout, and post-launch support. My experience includes XML, JSON, and RETS feeds, field mapping, FTP/SFTP delivery, REST APIs, SQL validation, and geolocation troubleshooting.

I am comfortable diagnosing technical issues using Postman, Swagger, browser DevTools, HTTP request analysis, authentication tokens, and status codes. I work closely with product and engineering teams by creating clear bug reports, reproducing issues, and supporting B2B partners in English.

My infrastructure support background includes Windows Server, RDP, TCP/IP networks, VPN tunnels, SIP telephony, Linux command-line tools, and POS-system support. I have administered client environments, maintained internal knowledge bases, and onboarded support engineers.

I use automation and AI tools daily to improve data verification and operational processes. I have built Google Apps Script utilities, worked with Google Workspace and reporting tools, and coordinated multilingual document-processing workflows. I am open to remote opportunities and relocation.
