Freelancer profile translated to English.

Description

I design backends that survive growth. I work with asynchronous services, robust authentication, multi-user systems, and real CI/CD pipelines — not prototypes. I'm passionate about integrating external APIs, LLMs, and intelligent automations, but my real obsession is making architectural decisions today that won't become technical debt tomorrow.

• • Developed an AI assistant chatbot (RAG + embeddings) for call center agents, integrating information on crane rental rates, distances, and prices. Reduced average quote time from ~5 minutes to under 30 seconds, improving accuracy and consistency of responses.
• • Integrated the Kimai API with a Next.js application to monitor employee work hours in real-time, automatically detecting deviations, exceeded breaks, and overtime. This allowed HR to manage work hour tracking without manual review.
• • Designed an automated workflow that processes 100% of daily calls, using AI assistants to evaluate compliance with internal protocols. It detects fraud alerts, identifies operational non-compliance, and generates actionable feedback for advisors, eliminating the need for manual sample audits.
• • Implemented a cancelled call detection workflow that automatically identifies the customer, responsible agent, reason, and time, feeding into management dashboards and improving business visibility for decision-making.
• • Built a web scraping system with Playwright, automated with CI/CD in GitHub Actions, that runs twice a week to extract information on potential crane suppliers. This optimized the acquisition of new strategic partners by eliminating hours of manual research for the sales team.

• • Implemented Celery with Redis for asynchronous queuing and processing of critical tasks (email sending, notifications, real-time messaging).
• • Utilized Redis as a caching layer to optimize response times and reduce costs on high-concurrency endpoints.
• • Developed the roles, permissions, and sessions module with granular access control based on JWT.
• • Integrated Agno Framework to build the MVP for disputes, enabling intelligent conversations between users and LLM agents within the conflict resolution flow.
