I'm an Upwork Expert Vetted writer who has helped over 100 B2B technology clients grow customer acquisition, LTV, and retention through compelling, engaging content. Always simplifying the complex, but never losing sight of the substance. My writing appears in Forbes and TechCrunch and past clients include Amazon, CloudLinux, and Infineon. Hire me now for blog content, thought leadership, case studies, whitepapers, sales enablement docs, etc - that gets results. --- The longer version: To produce convincing content in a complex technology domain you need a content partner who plays a dual role: analyst, and writer. Your content sidekick needs to develop a deep understanding of your service offering, your target market, and the technology environment you sell into (analyst) - and then utilize their mastery of language to communicate with impact (writer). I deliver the three essential skills you need: ✅ A deep understanding of the multi-stakeholder B2B buyer journey gained through experience in ITSM ✅ A unique knack to rapidly get to grips with complex (enterprise) technology products and services - the backstage stuff that the general public never hears about ✅ Cracking, clear, compelling copy and content PS: ✅ I'm adept at working with global, multicultural teams where subject matter experts don't speak English as a first language ✅ I do accept on one-off projects, but 80% of my work is for long-term clients What I deliver, how I work =================================================================== Count on me to deliver compelling content from thought leadership through to demand gen copy and everything in between. Always with a clear purpose and persona in view. See me as an extension of your team. I can deliver on minimal and non-existent briefs, taking the lead and developing your content from scratch, or follow your content plan to the last detail. Located in London, I work late hours and I routinely service clients from the West Coast through to Europe, the Middle East and Asia – even Australia. PS – I’ll write to your preference of English dictionary, whether US or UK (or Aussie!) What sets me apart =================================================================== FIRST – Exceptional, flexible copywriting skills You’ll get accurate, grammatically correct copy that is clear and compelling. I know how to engage an audience by using copy flow and cadence and I can do so even when the subject matter gets tough. I voice copy to meet your target audience whether that's Neil Patel-style copy or content that's at home on mckinsey.com. SECOND – An incredibly quick study with broad technology and finance know-how Do you find that every other writer you’ve hired struggles to understand your services and your vertical? My broad technology background and a degree from a rigorous economics school means I can get to grips with even the most complex environments. Result: working alongside your SMEs (or on my own) I can produce compelling content right from the start. THIRD – Established on Upwork 100% job success across 100 jobs... I take Upwork seriously, and I take your requirements seriously. I only bid if I’m confident I can meet or exceed your expectations. Quotes from my clients =================================================================== "Stephan, you've nailed it. This is precisely what I was envisioning." - Telecoms client, whitepaper project. "Sometimes, I think he knows more than we do about our own company. Highly recommended skilled writer with top business skills." – CMO in mobile infrastructure space. "Truly outstanding work. Stephan is a copy writing pro. Short copy, long copy. He nails it! Excellent writer and a quick study. He did such a great job on the assignment; I immediately gave him an additional project. " – Leading Silicon Valley marketer. "He does a great job explaining complex matters in an easy to understand way for non-techies. Stephan became an extension of our team. I would hire him again and I think you should too.” – CEO of Stockholm-based inbound marketing agency. "One of the best freelancers I have cooperated with. Experienced and qualified writer." – Marketing Director at enterprise software vendor. "Thank you for this, I'm really pleased with it. You really have captured the story I wanted to get across." – Commercial Director at London-based finance consultancy. Keyword cloud =================================================================== 5G AI AML analytics banking cloud compliance containers cybersecurity data development digital transformation edge computing enterprise finance fintech fraud hardware IaaS infosec infrastructure insurance IoT KYC machine learning management ML MNO PaaS payments payments predictive analytics resilience SaaS security services software tech technology thought leadership UX vulnerability management

I'm a Senior PHP Developer with over 20 years experience developing web applications and building and deploying API based solutions. Over half of that experience is working for London based Tech companies. I was a contractor for 5 years and am used to getting up to speed quickly with any new platform. I am currently working for Reward Gateway which is a Global Employee Rewards platform that services 6000+ clients worldwide with offices in US, Europe and Australia. Clients include Samsung, Ernst & Young, Deloitte, McDonalds, Heinekin, M&S, Sainsburys, Transport for London, etc I am able to work with a product owner or product team or even client directly to translate requirements into a full technical specification and then build (and manage) the full technical rollout. My time as a Business Analyst alows me to speak the language of both client and developer. I am happy to setup and handle meetings, present solutions, right through to eventually writing the code and delivering the tested solution. I do not deploy anything without 90% test coverage, both unit and/or functional tests. In addition to this, I am used to putting together end to end test cases in Browserstack too. I am often involved in working with QA (or managing QA entirely) to produce a suite of tests that ensure the feature we ship does what it should. I have a lot of experience monitoring with tools such as New Relic (and creating dashboards) and identifying issues early on and generally keeping an eye on things and working with Dev Ops to see that issues are fixed and dealt with.
