A decade shipping software

Teams and products where I've built systems that move the business forward.

  1. Fullstack Developer

    Kusit

    I developed multiple modules to optimize the company's internal ERP using technologies like JavaScript and PHP. I also built a fully functional ecommerce site connected to the internal system through a REST API for product synchronization. The project increased online sales by 20% in the first months.

  2. Fullstack Developer

    Lendinc

    I built a custom Laravel website focused on a strong user experience and robust functionality. I implemented SEO strategies using tools like Google Analytics and Moz to improve online visibility. These optimizations resulted in a 25% increase in web traffic and 15% growth in new leads.

  3. Web Developer - Systems Administrator

    Karati

    I handled end-to-end administration of technology services including servers, databases, and networks using tools like AWS and Docker. I managed the ecommerce site, improving UX and load speed. I also developed modules for the internal system, improving efficiency by 30% through process automation.

What I can build for you

From a single landing page to full custom systems — software built to grow with your business.

Website Design

Expand your brand reach with a custom website. It is not just about being online, it is about capturing potential customers already searching for what you offer. I can build anything from a landing page to more complex order and service management solutions.

Custom Systems

Every business needs an efficient system to manage resources. I provide fully customized solutions adapted to your needs, from inventory systems to CRM platforms. A custom system helps you optimize daily operations and scale with confidence.

Mobile App Development

Take your business to the next level with your own mobile app for both App Store and Play Store. I build custom solutions that connect you with your customers in ways websites cannot. Improve shopping experiences, real-time support, and more.

AI Business Automation

I automate repetitive workflows and decisions with AI to cut costs and speed up response times. I integrate with your existing tools to scale operations with clear metrics.
