SUMMARY
Junior QA Engineer with a background in IT monitoring and technical support: root-cause investigation, log analysis
(ELK, Zabbix) and incident documentation in Jira. Practical knowledge of manual and API testing: test cases,
checklists, bug reports, functional, regression, smoke and sanity testing, Postman and SQL data validation. I also build
AI automations in Python: my portfolio project, an LLM-powered lead routing system, includes guardrails against LLM
errors and 46 automated tests.

webhooks, REST APIs

WORK EXPERIENCE
Monitoring Specialist, JSC TascomBank Oct 2024 - Oct 2025
• Monitored high-availability enterprise IT infrastructure (~1,000 nodes) using Zabbix, ELK and vSphere.
• Investigated alerts, abnormal behavior and hardware/software failures from detection to root cause.
• Analyzed system logs and application error traces to isolate failures and provide detailed diagnostics.
• Maintained incident documentation and standard operating procedures; provided L2 support to bank employees.
HelpDesk Specialist, Boosta Jul 2026 - Aug 2026
• Supported users across Windows, macOS and Linux: network connectivity, DNS and mail-service issues.
• Reproduced user-reported issues across environments to find root causes; triaged and tracked them in Jira and
Slack.
• Documented recurring problems and resolution steps to improve system reliability.

QA TRAINING & PRACTICE
• Requirements analysis to find ambiguities, logical gaps and edge cases before test execution.
• Test documentation: test cases, checklists and test suites; test design with boundary values and equivalence
partitioning.
• Functional, smoke, sanity, regression, retesting, positive/negative and exploratory testing (black box).
• Bug reports in Jira with steps to reproduce, expected vs actual results, environment, severity/priority and evidence;
full bug life cycle.
• REST API testing in Postman: methods, parameters, headers, status codes, JSON response validation against
schemas.
• SQL queries to verify data persistence and UI-to-DB integrity; Linux CLI for log navigation.

PROJECT
AI Lead Qualifier & Router: personal portfolio project 2026
Python, FastAPI, LLM APIs (Gemini / Groq / Ollama), Pydantic, SQLite, Telegram Bot API, Google Sheets API, pytest
• Built an end-to-end automation for a home-services back office: a messy customer message becomes a qualified,
routed lead with a Telegram card for the manager in about 3 seconds.
• LLM extracts 15 structured fields (contacts, city, trade, urgency, missing info) from texts with typos, Spanish or
missing details; output is validated against a JSON schema with Pydantic.

• Designed guardrails so code, not the LLM, makes critical decisions: contact details must appear in the source
message, and contractor matching is rule-based and explainable.
• Telegram bot with one-tap Confirm / Reassign / Call first actions, SQLite event log, optional Google Sheets mirror;
resilient to rate limits, invalid LLM output and service failures.
• Demo on 15 difficult test leads: 15/15 processed, 4/4 emergencies detected, 73% auto-matched, average 3.4 s per
lead. 46 offline tests; runs at $0; LLM provider switchable in one line.
• Developed with AI-assisted coding (Google Antigravity, Claude). Source and demo:
