Your API documentation is either accelerating developer adoption — or quietly killing it. I help companies fix that. I'm Angel, a Senior Technical Writer and Frontend Developer with 4+ years of experience delivering documentation that measurably improves developer onboarding, API adoption, and product usability - primarily in fintech and SaaS. At Zest Payments (Stanbic IBTC), I led a complete overhaul of a developer portal serving 500+ developers: → 30% reduction in developer onboarding time → 25% increase in API adoption through validated Postman examples → 20% organic traffic growth via SEO-optimized documentation architecture → 100% elimination of Git leak security vulnerabilities Here's what makes me different: my background in React, Next.js, Angular, and TailwindCSS means I don't just write your documentation — I can build and maintain the platform that hosts it. That dual capability means fewer handoffs, faster delivery, and documentation that actually works in production. What I deliver: ✅ REST API reference documentation — endpoints, request/response schemas, error codes, authentication ✅ Developer portals built with Docusaurus, Docsify, and Astro Starlight ✅ Integration guides, QuickStart guides, and SDK documentation ✅ Release notes aligned with agile sprint cycles ✅ OpenAPI / Swagger specification documentation ✅ SEO-optimized documentation architecture — structured for findability, not just readability ✅ Documentation audits — clarity, structure, brand voice, and developer experience ✅ Technical writing for developers — tutorials, how-to guides, and onboarding flows My process is straightforward: I test every API endpoint I document using Postman, validate real-world examples before they reach your developers, and collaborate directly with your engineering team to ensure technical accuracy at every step.

I help businesses create clear, accurate technical documentation that simplifies complex processes and improves operational consistency. From user guides and SOPs to knowledge bases and onboarding documentation, I transform scattered information into practical resources teams can follow with confidence. WHAT I DO • Technical documentation • SOPs and process documentation • User guides and installation guides • Knowledge bases and onboarding documentation • Training materials and operational playbooks HOW I WORK I collaborate with subject matter experts to capture knowledge, structure complex information, and produce documentation that is accurate, practical, and easy to maintain. Where it adds value, I use AI-assisted workflows and automation tools to accelerate documentation while maintaining quality and consistency. RESULTS • Faster onboarding • Better documentation consistency • Reduced support requests • Improved operational efficiency BACKGROUND B.Eng. Electrical Engineering with over 10 years supporting technical operations, engineering documentation, and process improvement across engineering and technology-driven environments. TOOLS Notion • Google Workspace • Microsoft Office • ClickUp • Asana • ChatGPT • Claude • Zapier

I help SaaS companies turn complex products into clear documentation, scalable knowledge bases, and support systems that reduce ticket volume. Eight years of experience across SaaS, B2B software, fintech, media, e-commerce, and AI products, with teams in Nigeria, Singapore, Belgium, Hong Kong, and the UK. I work on both sides of the problem: I write the documentation, and I have handled the tickets. My docs answer the questions users are really asking, not the questions a product manager assumed they would ask. Documentation now does more than inform users. It shapes how AI agents, chatbots, and LLM-powered assistants understand your product. A knowledge base that confuses humans will confuse your AI agent too, just faster and at scale. I write content that is clear for users, useful for support teams, and structured well enough for AI systems to retrieve from reliably. What I help companies with User onboarding: helping new users reach value faster Feature adoption: making key capabilities easier to understand and use Help centers and knowledge bases: reducing support load through self-service API and developer documentation: REST API references, integration guides, webhook docs Internal documentation: SOPs, runbooks, workflows, support playbooks Technical support: Tier 2 and Tier 3 troubleshooting for API errors, OAuth flows, JSON debugging, frontend issues AI-powered support systems: improving retrieval quality for chatbots and AI agents Why clients hire me I build systems, not just pages. Scattered Google Docs and Slack threads become one structured knowledge system that is easy to use, maintain, and scale. I write for both users and technical audiences: user guides, API docs, developer references, and full PRD and SRS-style documents, not just help articles. I have sat in the ticket queue. I know how users break things, where they get confused, and what support teams are tired of repeating. I make documentation AI-ready. I structure content so tools like Intercom Fin, Zendesk AI, and Claude can retrieve knowledge accurately: information architecture, structured Markdown, troubleshooting paths, retrieval-friendly FAQs, and machine-readable layers such as llms.txt. I stay careful with AI. Automation works when it sits on top of real documentation and clear workflows. It fails when it is bolted on as a shortcut. Platforms and tools Documentation: Zendesk Help Center, Intercom, Notion, Confluence, GitBook, Help Scout, Freshdesk AI and support tools: Intercom Fin, Zendesk AI, Claude, ChatGPT Automation: n8n, Zapier, Make, Slack, Jira, ClickUp Technical: Markdown, JSON, REST APIs, webhooks, Chrome DevTools, JavaScript, HTML, CSS, React, Git Highlights of my experience I have worked with Prezly, Weeloy, Coinbag, Competitor Monitor, Linda Ikeji TV, Hemam Synergy, and MenuLogic K12. Prezly: contributed to developer docs, set up and synced their support stack (Zendesk, Jira, monday .com, Slack, ClickUp), ran demo calls and live training Hemam Synergy: wrote a full Product Requirements Document covering system behavior, workflows, and functional requirements MenuLogic K12: produced functional requirements documentation for the development team Linda Ikeji TV: built the FAQ and knowledge base, redesigned Zendesk workflows with automations and macros, and was part of a team effort that improved customer satisfaction by 26.4 percent. Training junior support staff saved an estimated $20,000 to $35,000 per year Weeloy and Coinbag: set up support software from scratch (Zendesk, Twilio, Jira, Zapier, Slack) and rewrote FAQ content customers could actually follow One client kept me on for over 600 hours. Another hired me for a small FAQ project and brought me back for their main product the next week. I follow up without being chased, and I do not disappear mid-project. Services I offer Documentation and Knowledge Bases: help center creation and restructuring, knowledge base architecture, user guides, onboarding flows, SOPs, runbooks API and Technical Documentation: REST API docs, integration guides, functional requirements, PRD/SRS documents, release notes Technical Support and Support Operations: Tier 2 and Tier 3 SaaS support, Zendesk and Intercom setup and optimization, macros, triggers, automations, SLAs AI-Ready Documentation and Automation: documentation structured for AI retrieval, knowledge base optimization for chatbots, AI-assisted workflows with human oversight built in If your product is moving faster than your documentation or support system can keep up with, that is the kind of work I do well. Let's turn your product knowledge into something clear, useful, and scalable.

Let me tell you about the results I got for my client, Jon. Jon has a simple business model. He’d create $297 health info products and launch them to his email list. And then he’d upsell his buyers with premium supplements and coaching programs. Jon’s business was doing $5 million a year when he hired me to write emails for a new launch. In my offer letter, he said: “Anthony, I’d love you to spearhead the emails and be our main man for that.” I did, and the result of that launch was amazing: ~$736k in two weeks of daily emailing. And the entire funnel was: 22 emails → landing page → checkout page → upsells (See my first portfolio item for this campaign’s stats. Please note that some details are redacted due to client request.) Jon’s team and I had 5 more launches with similar success. And I was compensated with $17,200 for my efforts. Let me tell you about another client, James. The Illinois State Government wanted to launch an online Law course for Chicago residents. And James got the $1.1 million contract to create the course and spearhead the program. James needed a sales page done for the course. So he hired me through Upwork to write it. I did, and the launch was a smashing success. James was so ecstatic that he wrote this glowing testimonial at the end of the project: “Anthony is a truly exceptional copywriter, the best I’ve discovered on Upwork. He’s a master. “In today’s competitive world, top-notch copywriting is crucial for success. The copy Anthony delivered was nothing short of a spectacular masterpiece. Having read many sales pages, I saw that Anthony’s work was in a league of its own. He went above and beyond, over-delivering on his promise and leaving us absolutely thrilled with the outcome. “I wholeheartedly recommend his services. Anthony’s work is a testament to the power of extraordinary copywriting. And I am beyond grateful for the opportunity to work with such a remarkable copywriter.” — James T., Just Us Bridge Law I wish I could share this campaign’s stats. But it was a part-government program, so signing an NDA was par for the course. Fortunately, I can show you the sales letter I wrote that launched the program. It’s the second portfolio item on my profile. I could go on and on about the results I’ve gotten for my clients. But I think you’re starting to get an idea of my skill level. I get results for clients because I’ve taken the pains to get good at copywriting. I’ve read all the classic copywriting books at least thrice. I’ve bought and studied dozens of sales courses. I’ve studied the psychology of human behavior. And I invest each year in my continuing education. But that’s not the only thing that’s responsible for my success. My main weapon is my mindset. I’m willing to do anything and everything possible to ensure that each project I work on will be an outstanding success. So before I write copy for a client, I sit down and do my due diligence: I study my prospects — their hopes, fears, dreams, and the ‘world’ they live in. I study my client’s competition — their products, their sales materials, and sometimes even buy from them to reverse-engineer their funnels. And then I study my client’s offer. By doing research in that order, I always find “big ideas” and hooks that’ll make my copy super-compelling. And the result? Sales copy that I know BEFORE it goes out that it’ll be a winner. If you are a client who wants outstanding results, this is the kind of copy you need. Copy that’s well-written. Copy that gets everything right. And why is this the kind of copy you need? Because competition is rife in almost every niche out there. On top of that, your prospects are bombarded with so much advertising clutter. So it’s no surprise that people won’t read your sales copy unless it gets everything right. Do you want copy that gets results? I may be able to help you. I specialize in direct response copywriting. And I write sales letters … emails … advertorials … and ads that get results. If you’d like to discuss a project, let's talk. At first, I’ll mostly ask a few questions and listen with undivided attention. If I’m convinced I can help you, I’ll let you know. I’ll also tell you what I’ll need from you, what you should expect, and the cost of my services. So message me. Or create a job post and invite me to it. Who knows? This may be the start of many successful projects between us! 𝐏.𝐒. Here are two more testimonials from my past clients: “Anthony gave me more value for free than any other freelancer I’ve ever worked with and I’ve hired over 50 of them. This guy knows marketing inside and out. He gave me a candid analysis of our ads and funnel without wanting to charge but I had to pay him because it was so valuable.” — Daniel S. CMO, Market Boost “Anthony is a very skilled copywriter. He understands the psychology of buying behavior and applies it in every piece of his work. I would recommend 10/10!” — Ashton M. CEO, Socially Elite
