📌 Seasoned Solutions Engineer [Notion, Automations, AI, & Business Operations Expert] — New to Upwork. Saved clients: ✅ 500+ hours of repetitive manual work ✅ Over $10k in unnecessary SaaS tool costs and team overhead. I design lean, scalable internal systems and workflows using Notion/Airtable as user-friendly interfaces, backed by tools such as n8n, Make.com, and Zapier for automation and integration. I help growing teams replace patched-together workflows with centralized, automated systems that cut manual work and scale as they grow. 🛠️ Highlighted Projects & Systems • Transformed a 30-step, 3-SOP process into a 2-step flow by building a dynamic Notion dashboard using formulas, buttons, and relational properties. Reduced time-to-publish from 2 hours to under 20 minutes per item. • Replaced a multi-tool email automation flow (Zapier + Google Sheets + Gmail + manual QA) with a centralized CRM in Notion backed by n8n, enabling fully automated, rule-based outreach with error logging and retry handling. • Developed a full job application system using Notion + n8n + Python (via HTTP requests) that included a custom ATS (applicant tracking system), email parsing, candidate scoring, and auto-tagging — all hosted on free-tier platforms. • Created dynamic dashboards for 30+ clients, each featuring automated task and project tracking, status updates, reminders, and due-date rollups — fully customizable without third-party apps. • Built “Second Brain” systems for solopreneurs, with connected databases for tasks, notes, resources, and goals. Leveraged automations and dynamic native formulas to reduce manual linking and eliminate redundant entry. • Designed onboarding systems for internal and client teams, including auto-inherited due dates, role-based task generation, and real-time progress visibility. 🌟A few words from some of my recent clients: “Working with Dineo felt like therapy for our workflows. We didn’t just get a Notion dashboard—we got our time and energy back.” ~ Lindsay Padilla, CEO - Hello Audio --- “I didn’t realize how much mental load I was carrying until it was gone. Now, I wake up, open one page, and everything I need is just… there. No more scattered apps. No more decision fatigue. Just clarity. This has genuinely changed how I work — and how I feel.” ~ Preshani Govender, Senior Project Manager - Amazon ZAF --- “I didn’t know what I needed — and honestly, I still don’t know how Dineo figured it out. But somehow, everything just works now. I don’t have to think about what to do, where to go, or who to ask — and I never realized how much time I was wasting here. Dineo built a system that quietly runs my entire life. I’ve got time back, my brain back, and more space for the people I love. Highly, highly recommend!” ~ Thato Mmaditla, Head of People - Capitec Bank ; Business Coach
