I am a chemistry/biology/physics PhD (the title itself was obtained at an engineering school but the context was systems biology) with a wealth of experience in scientific research. I have been a part of a few scientific research projects in the fields of chemistry/biomedicine/biophysics/omics and am a published author in my field(s). Other than working in a laboratory writing is what I enjoy the most. From writing poetry and short stories (mostly for my own pleasure) to essays and academic research papers, all things writing suit me. If they are related to science, even better. Even if they are not, I am a person of many interests, I adore history, culture, art, philosophy, etc. I am available also for diverse scientific work, including interpretation of analytical chemistry data (mass spec, NMR, HPLC), solving various problems in the fields of chemistry/physics/biology. I pride myself on being a very analytical and patient individual, as well as intelligent and able to grasp concepts previously unknown to me very quickly. I actually do this on a regular basis, challenge myself and try to learn about things outside of my main interests. When it comes to writing, I am familiar with most citation styles used in academia, and am able to follow guidelines well. I do have a specific writing style and I like to leave my distinct mark on the writing I do.

I help AI security platforms and MLOps tools create technical content that engineers trust, executives approve, and validate content quality before publication, so it doesn't damage credibility. **BACKGROUND:** PhD in Intelligent Control and AI (50+ publications, 382 citations, h-index 12), Expert-Vetted freelancer (Top 1%), $100K+ earned on Upwork, 70+ completed projects. **WHAT I DELIVER:** → Original AI Security Writing (1000+ published - Knostic) - White papers (5,000-8,000 words): Threat models, compliance frameworks, implementation roadmaps - Technical analysis blogs (2,000-3,000 words): Agent security, coding assistant threats, data leakage, prompt injection - Buyer guides: Security tool evaluation, framework comparisons (NIST AI RMF, ISO 27001/42001) - Case studies: Enterprise implementations with technical depth + business outcomes Examples from Knostic blog: - "AI Coding Agent Security: Threat Models and Protection Strategies" - "Building an AI Data Security Strategy From Scratch" - "Top Vibe Coding Security Risks and How to Fix Them" → ML/LLM Evaluation Content (250+ reviewed - Deepchecks) - Technical articles on LLM evaluation methodologies, benchmarks, and agent assessment - Content strategy + outline creation for complex ML topics - Review and editing for technical accuracy, methodology rigor, and claim defensibility Examples from the Deepchecks blog: - "LLM Agent Evaluation: Metrics, Methods & Real-World Use Cases" - "Top LLM Evaluation Benchmarks and How They Work" - "How To Evaluate State-Of-The-Art LLM Models: A Complete Guide" → Technical Review & Quality Control - 250+ Deepchecks articles validated for technical accuracy - 5000+ ODSC conference submissions reviewed (6 years) - Methodology verification, claim validation, and editorial for clarity - Catching errors before they damage platform credibility **WHY COMPANIES HIRE ME:** I'm not a "content writer who Googles stuff." I'm a PhD researcher who writes with reviewer-level rigor. When I write about AI agent security, I understand threat models and attack surfaces. When I review LLM evaluation content, I know benchmarking methodologies. When I create outlines, I map research requirements to evidence standards. My content passes technical review because I AM a technical reviewer. **HOW I WORK:** 1. Discovery Phase: Product capabilities, target buyers, competitive landscape, regulatory context 2. Research: Deep dive into technical architecture, threat models, use cases 3. Outline: Structure with inline citations, key claims flagged 4. Draft: Full content with citations, technical depth, business context 5. Revisions: Technical accuracy → audience fit → final polish 6. Delivery: Google Doc (formatted), reference list, meta descriptions
