Tailored software solutions for your business to dominate tomorrow’s possibilities

We build web applications for businesses that need their software to work under pressure. That means architecture designed for scale, security baked in from the first commit, and performance treated as a feature rather than an afterthought.

Most of what we build falls into one of three categories: custom web platforms for organizations running complex operations, ecommerce systems for businesses that have outgrown their off-the-shelf setup, and API layers that connect the systems a business already depends on into something that actually works together.

Custom Web Platforms

When an organization's processes are too specific for existing software, we build the platform that fits. We work primarily with Drupal for content-heavy applications and React for interfaces where responsiveness matters, backed by Node.js or PHP on the server side and PostgreSQL or MySQL for data.

The result is software that does what the organization needs rather than what a product roadmap somewhere decided was the next feature. We've built platforms for conservation programs managing field data across multiple countries, financial services companies handling sensitive transaction workflows, and advocacy organizations coordinating campaigns across dozens of partners.

Ecommerce Development

Ecommerce projects usually come to us after a business has hit the ceiling of what Shopify or WooCommerce can do without falling over. The catalog is too large, the checkout flow is too specific, or the integrations with inventory and fulfillment systems need to actually work reliably at volume.

We build custom ecommerce systems and extend existing platforms with proper payment gateway integration, inventory sync, and the kind of performance optimization that means your product pages load in under two seconds even when traffic spikes. Payment processing in East African markets comes with its own set of integration challenges — M-Pesa, card processing, multi-currency — and we've built for all of them.

API Development and Integration

Most businesses run on a stack of services that were never designed to talk to each other. We build the API layer that connects them: RESTful APIs, webhook integrations, real-time data sync, and the authentication and rate-limiting infrastructure that keeps it all secure.

API work is often the least visible part of a project and the part that determines whether everything else actually works. We treat it accordingly — documented endpoints, proper error handling, monitoring in production, and the kind of test coverage that catches breaking changes before your users do.

How We Work

Every project ships in two-week sprints. You see working software at the end of each one, not a progress report. We scope conservatively, communicate directly, and write about what we build on the blog — including the technical decisions and the trade-offs behind them.

What technologies does Gato Blanco use for web development?

We work primarily with Drupal and React on the frontend, PHP and Node.js on the backend, and PostgreSQL or MySQL for databases. We choose the stack based on what the project needs, not what's trending.

How long does a custom web application project take?

Most projects run 8 to 16 weeks depending on complexity. We ship in two-week sprints with working software delivered at each milestone, so you see progress from week two.

Does Gato Blanco build ecommerce platforms?

Yes. We build custom ecommerce systems and extend existing platforms for businesses that need performance, custom checkout flows, and reliable integrations with payment and fulfillment systems — including M-Pesa and multi-currency processing for East African markets.
