Updated on Jan 25, 2026

I’m Sergey, a senior technical writer with 10+ years of experience helping teams ship clear, consistent documentation for complex software. I work across end-user documentation, developer docs (APIs and SDKs), and documentation operations, with a strong focus on information architecture, standards, and scalable docs-as-code workflows. I partner closely with product, design, engineering, and support to turn fast-moving releases into guidance users can trust, and to build documentation systems that stay accurate as products evolve. Known for stepping in where needed, closing feedback loops, and raising the quality bar on clarity.

Work experience

Technical writer | Phantom (April 2025 - present) | Remote, Vietnam

At Phantom, I’m part of the Customer Happiness team, where I focus on making sure users always have clear, accurate, and helpful information at their fingertips. My work spans Help Center content (help.phantom.com), developer docs (docs.phantom.com) UI writing, user advocacy, and chatbot maintenance.

Highlights

  • Help Center quality and consistency: Restructured and standardized articles so users get the same reliable answers across Help Center and chatbot responses.
  • Day-one documentation: Built a process for launch-ready docs for major releases (including Phantom Cash, Prediction Markets, Perps, Terminal, Chats, and PSOL), with proactive updates as features evolve.
  • Style and standards: Revived the internal style guide and expanded it beyond Help Center docs to support UI writing and cross-team collaboration.
  • In-app clarity: Partnered on reviews for major features to keep in-app wording intuitive and user-friendly.
  • Cross-functional impact: Closed product loops by bringing user feedback to product and engineering teams.
