Worked on improving onboarding and configuration management across two repositories, meltano/meltano and tonkeeper/ton-assets. In meltano/meltano, focused on documentation accuracy by updating the Getting Started guide to reflect the correct CLI usage, ensuring new users encountered accurate command examples and output. For tonkeeper/ton-assets, expanded asset management capabilities by adding Changelly to the custodians list and introducing a new staking pool, Stakee, through clean, config-driven changes. Employed skills in backend development, configuration management, and data management, utilizing JSON, YAML, and Markdown to maintain clarity and auditability. Prioritized user experience and maintainability through precise, standards-aligned contributions.
