I help cybersecurity, SaaS, and cloud companies create clear technical content that builds trust, explains their value, and helps attract the right clients. With 6.5+ years of experience across IT networking, cybersecurity, secure software development, and technical research, I turn complex topics into clear, accurate writing that is practical and does not sound AI generated or generic. I can help with: • SEO-focused cybersecurity articles • B2B SaaS website copy and landing pages • Thought leadership content for CISOs, security leaders, technical teams, and executive buyers • Cloud security, compliance, and risk content • AI security and application security topics • Ebooks, white papers, case studies, and technical guides • Security policies, reports, and training material My background includes network security, cloud security, incident analysis, risk assessment, ISO 27001, NIST, GDPR, secure SDLC, Kali Linux, Burp Suite, and programming concepts across C, C++, Java, Python, and Rust. What makes my work different is that I do not just rewrite surface-level information. I understand the technical side, research deeply, and write in a way that helps your audience actually understand the problem, trust your solution, and take action. If you need clear and accurate technical content, I can help.

I started out as a software developer. I later pushed into technical writing. My first published articles focused on SQL Server and the .Net 4.0 / 4.5 Framework. Later on, I had the lead author role for The SQL Workshop (Packt Publishing). Here at Upwork, I have solved problems and added value for customers all around the world. I worked as a Senior Content Developer (Technical Writer) at Microsoft for almost three years, and after the 2025 Microsoft layoff waves (15000 and counting) I'm back at Upwork. Reach out. Tell me your requirements, and I will craft the high-quality written product(s) you need. I built documentation resources for Microsoft, and I can build those resources for you. Thank you!

Senior Technical Writer & Computer Engineer | Help Centers & Knowledge Bases I'm a senior technical writer with a computer engineering background who builds and owns complete documentation systems, not just individual docs. For my two most recent SaaS clients, I created help centers with hundreds of articles from scratch, as well as an interactive video certification program. Clients hire me when they want to hand off documentation entirely. I define the scope with your stakeholders, select and build the platform, write and structure every article, and keep it all up to date as your product evolves. I've delivered complete documentation sites in WordPress, GitBook, and Intercom, working directly with CEOs, VPs of Product, and Heads of Customer Success. I bring 13+ years of combined experience in computer engineering and technical writing, which means I don't need your engineers to translate for me. I understand systems the way the people who built them do: I learn your product hands-on, bring informed questions to developers and support teams, and write documentation that deflects support tickets instead of generating them. WHAT I DELIVER — Complete help centers and knowledge bases for SaaS platforms — API documentation — Quick start guides, user guides, and product manuals — Video certification and training programs — Documentation strategy: platform selection, information architecture, and scope HOW I WORK — I take ownership. You get a documentation partner, not a task-taker waiting for assignments. — I integrate all stakeholder feedback before publishing, and handle post-publish updates within 24 hours. — I have a proven Upwork track record of long-term contracts, because owning documentation is an ongoing relationship, not a one-off gig. If you want someone to own your documentation end-to-end, or need guidance on strategy before committing, message me and tell me about your product.
