Websites and Flutter apps built from Colombia, in US time zones: sites that bring in customers and apps for iPhone and Android, with one person accountable from start to finish.
Daniel Agamez 10+ years, 30 projects and apps with more than 10,000 downloads on Google Play.
You don't pay a designer and a developer who don't understand each other. What you approve in the design is exactly what ships to the store.
Your app works the same on all three platforms. You pay for one build, not three, and every improvement reaches all your users the same day.
Apps live on the App Store and Google Play with more than 10,000 downloads, websites for clients in Colombia and the US, and web invitations for events.
Radio EsperanzaOfficial app of 1140 AM radio station in Cartagena
The live station in every listener's pocket. The stream keeps playing with the screen off, can be controlled from the lock screen, and has a sleep timer and a share button.
I designed it, built it in Flutter and keep it live on Google Play and the App Store.
PanicTalkAI speaking coach for English learners
The app drops you into a real work situation, like a daily stand-up or a client call, and gives you seconds to answer out loud. AI listens to your audio and corrects your pronunciation using Spanish spelling, so learners hear exactly what to fix.
I built the whole product: design, the Flutter app, subscriptions with a free trial and the App Store and Google Play listings.
Website for a US keynote speaker and author
Site with blog, podcast, book and speaking pages, managed from a CMS so the client publishes without needing a developer. Built with the Allan Solutions team.
Next.js, Payload CMS, Cloudflare
CRM for selling on WhatsApp
Platform for sales teams on the official WhatsApp Business API: multi-agent inbox, contact CRM, campaigns, Kanban pipeline and real-time metrics, with AI that suggests and polishes replies.
I built all of it: NestJS backend, Angular web dashboard, the landing page and the Flutter mobile app, all on the same backend.

On a call I can walk you through how I approached each project.
Hire me for one part or the whole journey. Either way you work with me directly, with no middleman.
Company websites, landing pages, online stores and web invitations for quinceañeras and weddings. Custom design, fast on mobile and built to be found on Google and to bring in leads.
One Flutter app for both stores, with sign-in, payments, notifications or whatever your business needs. I also handle the store launch.
Admin dashboards, CRMs, booking or ordering systems and integrations with WhatsApp, payments or your accounting software. Web and app on the same system.
Figma design so you approve every screen before any code. After launch, improvements and support with fixed monthly hours.
Every project has its own timeline, agreed in the proposal. What never changes: you see real progress every week, so you always know where things stand.
We get to know your customers, the goal and what goes into version one. You leave with a fixed scope, delivery date and price.
I design every screen in Figma and you approve it before any code. Nothing gets built blind.
I build in increments: every week you see real progress in your browser or on your phone.
Release on Google, the App Store or Google Play, with analytics on and support after launch.
Through ideas, decisions and refinements, I shape digital products. I look for balance between logic and experience, between what works and what feels good to use. Since 2015 I've delivered more than 30 projects for companies in Colombia and abroad.

After a 30-minute call I send you a fixed-price proposal. You pay by milestones, never everything upfront.
To get found on Google and turn visitors into leads.
To be on the App Store and Google Play, right in your customers' pockets.
To run your operation online: orders, bookings, a CRM or an internal system.
It depends on the number of screens and features such as payments, sign-in or an admin panel. After a 30-minute call I send you a fixed-price proposal with milestone payments, no strings attached.
It depends on the number of pages and whether it includes an online store. The proposal gives you a specific delivery date, and you see progress every week and approve it before launch.
Flutter gives you one app for iOS, Android and web. It costs and takes about half of two native apps, and every change reaches all platforms the same day. If your product needs something very platform-specific, it plugs in native code without rebuilding the app.
Yes. Everything lives in your repository and your Figma account from day one. At the end you get documentation so any Flutter developer can continue.
Of course. I review your screens, flag anything worth adjusting for mobile and build them as they are.
Yes. Colombia is in UTC-5, the same as US Eastern Standard Time, so calls and reviews happen during your working day. More on hiring a Flutter developer in Colombia.
By milestones: one part to start and the rest on approved deliveries, invoiced in US dollars.
Pick a website, an app or a platform and watch it come together. I'll reply with a fixed-price proposal, no strings attached.
