SUMMARY
Focused Python Developer with 4 years of experience in backend and full-stack development, specializing in high-traffic platforms. Seeking opportunities
to drive innovation and scalability through advanced API integration and efficient system design.
EXPERIENCE
Python Developer (Backend/Full-Stack)
WebStudio February 2025 - January 2026, Warsaw, Poland
• Owned backend services for a high-traffic video platform (100k+ DAU, 20k+ videos).
• Improved performance by 50%+ through query optimization, caching, and backend refactoring; stabilized latency under load.
• Built and maintained REST APIs with Django/DRF; integrated third-party services via APIs and webhooks.
• Implemented background processing using Redis and Celery/RQ to offload heavy workloads and improve responsiveness.
• Delivered LLM-driven automation and analysis features via external model APIs; supported Docker-based deployments on Linux.
Freelance Python Developer
Freelancehunt / Upwork / Useme February 2022 - May 2025, Remote
• Delivered Django-based platforms and REST APIs for clients (admin panels, third-party integrations, automation tooling).
• Built ingestion pipelines processing 150+ new records/day from 4 sources; implemented normalization, validation, and deduplication.
• Integrated payment providers and external REST APIs; improved transaction reliability and streamlined checkout/data flow across client systems.
• Developed Telegram bots and internal tools to automate support and operational workflows; maintained and debugged legacy PHP modules.
• Designed PostgreSQL schemas and optimized queries; used Redis caching/queues to improve responsiveness and throughput.
• Delivered client features end-to-end (requirements → implementation → deployment) and supported production releases.
PROJECT
LLM Integrations for Web Platforms
NDA • January 2024 - September 2025
• Integrated LLM features into web platforms, shipping multiple assistant-style workflows for analysis and automation.
• Implemented structured outputs (JSON schemas / function calling) across several production flows to reduce invalid responses.
• Built prompt templates and routing logic for multiple user intents, including edge-case handling for stability.
• Added evaluation and logging for prompts/responses to support ongoing iterations and production debugging.
• Implemented safety constraints and fallback flows to keep behavior predictable in production.
Multi-source Data Ingestion Pipeline
Freelance • December 2022 - February 2024
• Processed 150+ records/day from 4 sources (APIs and parsing); implemented deduplication and automated retries.
• Normalized and validated incoming data across 4 heterogeneous sources, reducing invalid/duplicate records and stabilizing downstream processing.
• Implemented rate-limit handling and idempotent processing with retry/backoff to reduce ingestion failures and improve production reliability.
High-load Video Platform (NDA)
NDA • August 2022 - February 2023
• Supported a high-traffic video platform serving 100k+ DAU and managing 20k+ videos.
• Improved performance by 50%+ through query optimization, caching, and backend refactoring.
• Built and maintained REST APIs (Django/DRF) for content delivery and platform operations under load.
• Implemented background jobs and operational tooling to ensure stable processing during peak traffic.
• Improved reliability with rate-limit handling, retries, and monitoring-friendly logging for production debugging.
