Many companies end up with several systems that don't talk to each other: the ERP doesn't communicate with the online store, the CRM isn't automatically updated with billing, and the team ends up entering the same information two or three times across different tools. That friction isn't solved by adding more software, but by connecting what already exists, so data flows automatically between systems instead of depending on someone copying and pasting. This tends to become critical as a company grows: what used to be solved by copying data by hand between two or three systems stops being sustainable once the volume of operations increases.

We develop and implement APIs, interfaces and connectors to interconnect internal and external systems: microservices, REST web services and integration layers between platforms that currently operate in isolation. This includes building a company's own API so other systems can consume its data in a controlled way, as well as implementing and adapting connectors to use third-party APIs within an existing platform, with authentication, error handling, retries and activity logging, so integrations stay reliable and don't fail silently. This work ranges from a single connector between two systems to a full integration layer coordinating several platforms at once. We also document every integration, so the client's team understands what data moves between which systems and can provide support going forward without depending exclusively on us.

For example, a services company that issues invoices in an accounting system separate from the CRM where it manages clients could connect the two so every sale is invoiced automatically, without double entry. A chain of stores taking orders through different channels — a website, WhatsApp, a marketplace — could centralize everything into a single stock management point, avoiding overselling caused by each channel tracking its own inventory separately. A company operating in several countries could centralize the validation of each market's tax and banking data through a common integration layer, instead of duplicating that logic in every local system.

We have experience integrating payment APIs (Stripe, PayPal, MercadoPago), messaging (WhatsApp Business, Twilio), transactional email (SendGrid, Mailgun), storage (Amazon S3, Google Drive), maps and geolocation (Google Maps), and language models from Anthropic and OpenAI for classification and data-extraction tasks. These integrations are often the technical foundation for later cross-system automation projects. In every case, we prioritize the security of the credentials and data moving between systems, following each provider's best practices.
