We work together step by step. You'll always know where your project stands.

I learn your business, your users and your goals. We define scope and a realistic plan.

We turn the idea into clear flows and an interface. We validate before writing a line of code.

We ship, measure and improve. I stay on after launch so everything scales smoothly.
Your technical partner,
not just a coder
I'm Yeison Valencia, a full-stack developer with 4+ years building mobile apps and web platforms for businesses and startups. I work from Pereira, Colombia, with local and international clients.
I'm obsessed with products that don't just work, but drive results: that people use, recommend and that grow your business. I speak your language, technical or not.
If you're looking for someone who takes your idea seriously, tells you the truth and ships it to production, let's talk.
Clear communication, no unnecessary jargon
Frequent deliveries and deadlines met
Clean, scalable and maintainable code
What people who
trusted me say
The best proof is the result and the experience of working together.
Yeison understood our idea better than we did and turned it into an app our users love. Professional, clear and always on time.
We launched our MVP in weeks, not months. The code quality and communication were excellent.
We needed a technical partner we could trust and we found one. I recommend working with Yeison without hesitation.
What people usually ask
before starting
Have another question? Write to me and I'll answer personally.
How much does it cost to build a mobile app or a web platform?
It depends on scope, but I always work with clear, phased budgets. After a discovery call I give you a realistic estimate with no hidden costs. Many projects start as a scoped MVP to validate fast and control the investment.
How long will my project take?
An MVP usually takes 4 to 10 weeks depending on complexity. I work in short cycles with frequent deliveries, so you see progress every week instead of waiting months in the dark.
Flutter, React Native or native? What's right for me?
For most products I recommend Flutter or React Native: a single codebase for iOS and Android, lower cost and time, without sacrificing quality. On the call we review your case and I pick the best option for your goals.
Do you work with clients outside Colombia?
Yes. I work 100% remotely with clients in Latin America, the United States and Europe. I adapt to your time zone and handle projects in both English and Spanish.
What happens after launch? Do you offer support?
Yes. Launch isn't the end. I offer support, maintenance and new iterations so your product scales and keeps improving with real usage data.
I have an idea but I'm not technical, can you help?
Absolutely. Many of my clients aren't technical. I guide you through every decision in plain language and handle all the technical work so you can focus on your business.
