# Web and mobile apps for non-technical founders. Built by someone who thinks like a CTO. I scope, build and launch your product, and I'll tell you when something won't work. - You own the code and accounts - Plain-language updates - Based in Europe, working remotely **5.0** on every rated project **3 live products** I run the technology for **iOS, Android, web**: from first version to the stores ## For founders with a clear idea and no tech team You know the problem you're solving and who it's for. What you don't have is a technical co-founder, and you're not ready to hire a developer full-time. You need someone who can turn the idea into a real product, and who cares whether it's the right product. **I also work with small businesses** that need a custom web or mobile tool, or an internal tool to replace the spreadsheets. ### Building your first product shouldn't feel like a gamble - **“I don't know what to build first.”** Every feature feels essential, and the budget is finite. - **“I can't judge the tech choices.”** Which stack, which platform, native or web? You're asked to decide things you can't evaluate. - **“I'm afraid of paying for the wrong thing.”** Many developers build exactly what's in the brief, even when the brief is wrong. - **“The non-code parts stall everything.”** Accounts, payments, app stores, hosting, handover. ## From first version to live product ### Web apps and SaaS Customer-facing products, dashboards and platforms, built to grow. ### Mobile apps iOS and Android apps, from first version to the App Store and Google Play. ### MVPs on a lean budget A focused first version that tests the idea before you spend more. ### Internal tools and automation Custom tools and workflows that take repetitive work off small teams. ## From idea to launch, in four steps 1. **Understand.** I start with your business, not a feature list. What problem are we solving, for whom, and what would success look like? 2. **Scope.** I turn the idea into a clear plan: what to build first, what to leave out, which technology, and what it will cost. If something won't work, you'll hear it here, before money is spent. 3. **Build.** Short milestones you can click through and test. Plain-language updates, no jargon. 4. **Launch and hand over.** I handle the setup that usually stalls founders: hosting, payments, app stores. You end up owning everything and understanding how it works. After launch, I can stay on as your part-time CTO. ## A developer who thinks like a partner ### Business first Before building software I managed IT and automation projects for an insurance multinational and for agencies, so I start from the problem you're solving, not the ticket in front of me. ### Honest advice I'll challenge an idea when it won't work, and sometimes the right answer is a simpler, cheaper or even non-technical fix. ### Plain language You'll always know where the project stands and why each decision was made. ### You own it Code, accounts and documentation are yours from day one. No lock-in. ## Live products I run the technology for ### fiid.io: workplace safety platform for small businesses Employees report hazards with a photo or voice note, complete inspections and confirm they've read announcements. Admins follow everything in a web portal, and insurers and safety consultants manage their client companies. Includes an AI assistant that answers questions from the company's own data. - Platforms: iOS, Android, web - Live: 6 languages, monthly subscription - Stack: React Native, Expo, Supabase, Hono *Part-time CTO* ### Training and coaching app for gyms and clinics Coaches build programmes and follow members' progress.

Each gym gets the app in its own branding. - Platforms: iOS, Android - Data: EU servers - Stack: React Native, Expo, Supabase, Hono *Part-time CTO* ### Anfalia: protection for people who live across borders A peer-to-peer protection community for expats, digital nomads and mobile workers, whose cover moves with them. I co-founded it and lead the technology. - Platforms: Web - Stack: React, Supabase *Co-founder, tech lead* On every project: scoping, architecture, building, app store and hosting setup, and ongoing development. ## Rated 5.0 on every reviewed project Reviews from verified Upwork clients > “Hard worker, understands the bigger picture, pleasant to work with.” Repeat client, ROI calculator project > “He has more of an eye for detail than any other freelancer I've worked with on this platform… he clearly knows European quality standards.” Client, AI coaching assistant > “He helped me understand what was wrong with my Bubble app in under 20 minutes. Great communication… 100% hiring again.” Founder, app consultation ## Hi, I'm Coen. I founded Elcovate to be the technical partner I'd want if I were a non-technical founder: someone who builds well, explains clearly, and tells you the truth about your idea. Before building software, I managed IT and automation projects for an insurance multinational and for agencies. That's where I learned to start with how a business actually works, and to spot when the planned solution isn't the right one. Today I build web and mobile apps for founders and small companies, and act as part-time CTO for two startups, alongside co-founding my own.

No. Most of the founders I work with don't have one. You'll get plain-language updates and the reason behind every decision, so you always know where the project stands. ### What does it cost to build my app? That depends on what we build first. In the scoping step you get a clear plan: what to build first, what to leave out, which technology, and what it will cost. You see the cost before any money is spent on building. ### Who owns the code and the accounts? You do, from day one: the code, the accounts and the documentation. No lock-in. ### Do you build for both iPhone and Android? Yes. I build iOS and Android apps and web apps, and handle the App Store and Google Play setup. ### I already have a product that needs work. Can you help? Yes. I start by looking at what's there and tell you honestly what's worth keeping and what isn't. ### What happens after launch? After launch, I can stay on as your part-time CTO for ongoing development and the technical decisions that come next. ## Tell me about your idea A few lines is enough. I'll read it properly and reply within two working days with honest first thoughts, and whether I'm the right fit. Prefer email?
