Hire the Best API Developers
in South Africa

I've been writing code for money for 30 years. I'm not a big-hitter high-stress guy, but I know what I can handle. Python, Typescript, lately a bit of Rust, it's all just code. I know how to work with an existing codebase. I know how to balance time and technical debt. I know how to use the AI without losing my way. I don't work on Windows.

👋 My name is Gavin Wiener, and over the last 8 years, I’ve helped 100+ B2B & B2C businesses generate more leads, book more sales calls, and scale revenue faster, by building high-converting sales funnels, automating workflows, and managing their paid Facebook and Instagram ads. I’ve worked with happy clients worldwide, combining my background in Business Science & Computer Science with proven marketing frameworks to deliver systems that don’t just work, they scale. Many of my clients have gone to multiple seven-figure months by automating their lead generation, lead nurturing, and reporting 💰 I began my career as a software developer at South Africa’s most popular online fashion business Superbalist. I worked closely with the marketing, web development, and HR teams to build internal tools that helped streamline the business. That experience gave me a strong technical foundation, which I’ve carried into automation and funnel building. Since 2016, I’ve been running Gavin Wiener Consulting & Automation, where I specialize in building automated sales funnels that convert more leads, automating manual sales processes, and helping clients with their Meta paid ads campaigns, so that they make more money, and save hundred of hours each month. Some of the results I've generated for clients on Meta: For a dentist in Atlanta, I ran a landing page campaign with a special offer and generated 29 leads in 28 days at a $23 cost per lead. A Florida real estate agent needed more buyer leads fast. We ran an instant form campaign and pulled in 17 leads in just 14 days at $5.97 per lead. Another Florida real estate agent came to me looking for consistent lead flow. Over 4 months, a DM campaign brought in 488 leads at $4.96 per lead. During a 20-day launch for an online therapist in California, we drove traffic to a landing page and closed out the campaign with 17 leads at $30.39 per lead. 🧩 I work with no-code and automation tools such as: - N8N - Zapier - HubSpot - Make (Integromat) - Mailchimp - ActiveCampaign - Brevo (SendinBlue) - Klaviyo …and more. With my background in software engineering, I was able to master these tools quickly and apply them to real business growth 👨‍💻 Here is one of my recent success stories: 1️⃣ Chris runs a freelancing YouTube channel with 13,000+ subscribers. He needed help turning those viewers into paying customers. First, we built him an opt-in page with a free resource. Viewers had to enter their name and email to get it. This got people on his email list. Next, we created a sales page for his 14-day freelancing course. Then we set up email automations that sold the course to his list. We also built automations that onboarded new students automatically. The result? Chris now has a system that turns subscribers into customers without him lifting a finger. In addition, over the last 7 years I’ve worked with a wide range of funnels… 🎯 Funnels I Design & Build - VSL Funnels - Opt-In Funnels - Webinar Funnels - Application Funnels - Membership Funnels - Lead Magnet Funnels - “Book a Call” Funnels - Low-Ticket Offer Funnels - Automatic Client (AC) Funnels 🧱Funnel Builders I Work With - GoHighLevel (HighLevel) - ClickFunnels - Kartra - Carrd - WordPress + Elementor Client Testimonials ⭐⭐⭐⭐⭐ “Gavin made a significant impact… helped us automate, saving money on software costs and lowering expenses… also improved our sales processes so we can generate more revenue.” — Liam K, Coaching Business ⭐⭐⭐⭐⭐ “Within days Gavin had all my systems running — Facebook ads, chatbot, and email sequence — after I’d been stuck for weeks.” — Billy W, Fitness Coach 🤝 My Promise to You If you’re not happy, I’m not happy.
