Struggling to launch your SaaS idea or turn your startup MVP into a fast, scalable product? Or frustrated that your non-technical team is stuck waiting on a developer every time they need to update content? You're bleeding time, momentum, and revenue you can't afford to lose. I help SaaS founders and early-stage startups fix exactly that. My approach blends deep expertise in modern frontend development (Next.js & React.js) with UI/UX design, backend development (Node.js, Express.js, PostgreSQL), and headless CMS architecture (Sanity + Strapi) — delivering clean, high-performance, production-ready applications that load fast, rank higher in search, scale without breaking, and give your team full content management control without touching code. ✦ Rising Talent on Upwork — awarded to the top emerging freelancers on the platform ✦ 100% Job Success Score across every client and every project ✦ 10 projects shipped across SaaS, headless CMS, AI integrations, and e-commerce — on time, and on scope ✦ Zero disappointed clients. That is not luck. That is how I work. When it comes to scalable MVPs and headless CMS, I'm your competitive advantage. I don't just write code. I take ownership of your product the way a founding engineer would. I can help you: ✓ Launch your SaaS MVPs & web applications using Next.js architecture with authentication (Clerk, Supabase, NextAuth), payments (Stripe or Paystack), REST APIs, AI features (OpenAI, Claude), and every integration you need to go live fast without sacrificing quality. ✓ Build backend services your product can grow on. Scalable REST APIs, Node.js, Express.js, PostgreSQL, MongoDB, Supabase, or Firebase, structured so your data is clean, your endpoints are fast, and your app handles real traffic without breaking. ✓ Deploy headless CMS setups that eliminate developer dependency. Sanity, Strapi, Contentful, Prismic, or WordPress with WPGraphQL, so your team can publish and manage content completely on their own. ✓ Develop content-rich sites & documentation with MDX, headless CMS, and React components. Fast, SEO-optimized, and easy for your team to scale. ✓ Craft high-converting landing pages & marketing sites with React.js, Next.js, and Tailwind CSS that load under 2 seconds with 90+ PageSpeed scores, built around one goal: turning visitors into customers. ✓ Translate Figma designs into production-ready products and modernize legacy web apps. Pixel-perfect, fully responsive TypeScript + React + Tailwind builds, structured for long-term scalability rather than short-term convenience. ✓ Build e-commerce storefronts with Next.js, Stripe, or Paystack, dynamic product pages, and SEO foundations built to drive organic traffic and convert browsers into buyers. 🤝 My process: Most developers go quiet after you hire them. I do the opposite. 1. Kickoff call. We align on your product, your users, and what success actually looks like. 2. Architecture & planning. I map out the full structure and hand you a clear timeline before a single line of code is written. 3. Build & integrate. Figma designs become clean production components. APIs and payment flows are built, connected, and tested. 4. Deploy & refine. Everything ships and gets refined until performance is exactly where it needs to be. Throughout the entire process, you get regular Loom video updates, screenshots, and live working builds so you can test features as they come together. You always know where things stand and what is coming next. No fluff, no surprises. 🛠 Tech I work with: → Frontend: React, Next.js, TypeScript, JavaScript, Astro → Styling: Tailwind CSS, SCSS, Shadcn/UI, Radix UI, Material UI, Framer Motion, GSAP → Backend: Node.js, Express.js → Database: PostgreSQL, MongoDB, Supabase, Firebase, Neon → CMS: Sanity, Strapi, Contentful, Prismic, Payload, Headless WordPress/WooCommerce → Integrations: REST APIs, GraphQL, Cloudinary, Prisma → Payments & Auth: Stripe, Paystack, Clerk, NextAuth, Supabase Auth → AI: OpenAI API, GPT-4, Whisper, Claude → Deployment: AWS, Vercel, Netlify, Hetzner 🏆 What a recent client said: "Working with Divine was one of the best decisions we made for our business. He built us a clean, high-converting landing page, and we saw a 25% increase in online orders shortly after launch. Communication was smooth, and deadlines were met. I'd gladly work with him again." — Jonas O., TastyBite If you're building a SaaS or MVP and you want it done right — send me a message. I'll give you an honest breakdown of your project and exactly what it would take to ship it, usually within a few hours.

You need a product engineer who can take your SaaS from messy scope to a stable production release without splitting responsibility across multiple freelancers. Your product gets built with clear technical ownership from requirements to architecture, backend, frontend, and deployment, with decisions based on business flows (not generic boilerplate). What your team gets - Product and technical scoping that separates MVP-critical features from later phases - Architecture and data modeling designed around real workflows (auth, roles, payments, async processing, admin/customer portals) - End-to-end implementation across frontend, backend APIs, database, and infrastructure - Secure, production-ready patterns: RBAC, token/session strategy, validation, error handling, retries, queues/workers - Integration support for common SaaS needs (payments, email/notifications, background jobs, dashboards) - Deployment and handoff with docs/runbooks so you are not blocked after launch Typical projects - SaaS MVPs and internal platforms - Admin dashboards + customer portals - Booking/quote/invoicing workflows - API-first backends for web/mobile apps - Systems that require asynchronous processing (ingestion, queues, worker jobs, scheduled tasks) Deliverables - Product scope and execution plan with clear MVP boundaries - Technical architecture and database design aligned with your business workflows - Production-ready frontend + backend implementation (UI, APIs, auth, roles, core flows) - Integrations setup (payments, email/notifications, external APIs as needed) - Async processing setup where needed (queues, workers, scheduled/background jobs) - Deployment configuration (environment setup, hosting, domain/connectivity support) - Quality and reliability baseline (validation, error handling, logging, key edge-case coverage) - Handoff package: codebase, documentation, and runbook for smooth team takeover Core stack - Frontend: Next.js, React, TypeScript - Backend: Node.js/TypeScript, API architecture, async workers - Data: PostgreSQL, Supabase, schema/migration workflows - Integrations: Stripe, email flows, auth/permissions - Deployment: Vercel and cloud-hosted environments If your SaaS is still in idea or messy-build stage, share the context and get a practical plan to move it to production.
