PROFILE

Josef Procházka

Worked across multiple Apify repositories to deliver features and fixes that improved platform reliability, developer experience, and AI integration. In apify/apify-sdk-python, introduced dynamic request list creation and async-safe data iteration using Python and unit testing, while stabilizing dependencies for compatibility. Enhanced error handling in apify/apify-client-python by expanding API error parsing for both sync and async HTTP clients. Improved documentation readability and CI reliability through code formatting and configuration management. Developed a Python AI Agent template with PydanticAI in apify/actor-templates, and implemented timeout inheritance for actor orchestration in apify-sdk-js using TypeScript and full stack development practices.

Dec 1, 2025

December 2025 monthly summary for apify-sdk-js: Delivered the inherit timeout option for new Actor runs, enabling downstream Actor runs to inherit the remaining time from the parent run. Feature covers Actor.call, Actor.start, and Actor.callTask with a RemainingTime timeout model. This improves orchestration reliability and resource efficiency and aligns with cross-language consistency efforts (Python implementation and client libraries).

Mar 1, 2025

March 2025 monthly summary for Apify development. Focused on platform safety and developer onboarding, delivering features in apify/apify-sdk-python and apify/actor-templates that reduce risk, accelerate AI-enabled actor development, and improve observability. Key initiatives spanned automatic runtime safety in the Apify platform and a reusable Python AI Agent Template that streamlines onboarding and monetization.

Dec 1, 2024

December 2024 – apify/apify-client-python: Enhanced error visibility and reliability by expanding ApifyApiError to parse and expose the API's error data. Focused on a single feature that improves error diagnostics across both synchronous and asynchronous HTTP clients, with dedicated unit tests to validate behavior. This work strengthens client integrations, shortens debugging cycles, and lays groundwork for improved incident response.

Nov 1, 2024

November 2024 monthly summary for apify/apify-sdk-python: - Key features delivered: - Dynamic User-Input RequestList: introduced a new RequestList class extending crawlee.storages.RequestList to dynamically create request lists from URLs or lists of requests; includes parsing/fetching logic and unit tests. (commit c14fb9a9527c8b699e32ed49d39ce0a69447f87c) - Major bugs fixed: - Websockets Version Constraint to Preserve Compatibility: cap websockets to <14.0.0 in pyproject.toml to prevent installing versions with backward-incompatible changes that would break the current codebase. (commit 15ad0550e7a5508adff3eb35511248c611a0f595) - Async-safe Dataset.iter_items for apify_storage_client: fix Dataset.iter_items to function correctly with asynchronous iteration; add test verifying behavior. (commit 2db1beb2d56a7e7954cd76023d1273c7546d7cbf) - Overall impact and accomplishments: - Increased stability and compatibility of the SDK by preventing breaking dependency upgrades. - Enhanced data ingestion flexibility with dynamic request lists and improved reliability of async data iteration. - Expanded test coverage to reduce regression risk in future releases. - Technologies/skills demonstrated: - Python packaging and dependency management, asynchronous programming patterns, unit testing, and extending existing components (RequestList) with test-driven development.
