👋 Hello! I’m David — a medical writer with an MD and 9+ years of experience in systematic review and literature review, with a particular focus on evidence synthesis. I help researchers, consultancies, and healthcare organizations plan, conduct, and publish systematic review projects, from early protocol development to final manuscript submission. 📚 I follow internationally recognized systematic review methodology and reporting standards, including PRISMA guidelines, GRADE, structured screening workflows, and reproducible search strategies. My experience in systematic review projects includes protocol development, transparent documentation of the systematic review process, and preparation of publication-ready manuscripts that meet the expectations of peer-reviewed journals. 🔬 In addition to medical and scientific writing, I am proficient in the full workflow of producing a systematic review: from systematic literature search and article retrieval to data extraction, data management, statistical analysis, and meta-analysis (including network meta-analysis). My toolset includes R with relevant libraries, Rayyan, RevMan, and DistillerSR, allowing efficient and reproducible evidence synthesis. 📄 I can deliver content across multiple formats, including manuscripts, slide decks, interactive learning modules, and video-based educational materials. I am also comfortable working in multicultural and multidisciplinary environments, collaborating regularly with internal teams and external stakeholders. ⚙️ To ensure smooth collaboration, I share and export deliverables in commonly used formats such as Word documents and Zotero/EndNote libraries, making it easy to integrate my work directly into your systematic review workflow. 📊 Whether you need a fully managed systematic review or targeted support—such as refining a PICO question, developing a search strategy, or conducting specific stages of a systematic review—I can help. With my experience in systematic review methodology, I can contribute at any stage of the project, from pre-protocol planning to final manuscript polishing and responding to peer-review comments. 🎓 I also offer video consultations. If you need guidance on the next steps of your project, feel free to book a call. I have been teaching systematic review methodology at the MSc level for the past five years, and I’m happy to help clarify concepts or troubleshoot methodological challenges. 🌍 Finally, you should not expect language barriers to be an issue — my English is more than sufficient for discussing complex research questions and delivering high-quality work.
