About this gig

Most API integrations fail in production not in sandbox. The authentication breaks, webhooks stop firing, and transaction processing returns errors that nobody tested for. By the time the client notices, the damage is already done and the developer is gone.


We have been working with fintech APIs long enough to know exactly where those failures happen. Plaid, Stripe, and Dwolla are tools we use daily not occasionally. We understand how they behave under real conditions, how they talk to each other, and what breaks when they do not.


Here is how we approach every integration. We map your requirements before touching the code, build against both sandbox and live environments, handle edge cases that most developers skip, and hand you something that is tested end to end before delivery.


If you are building a financial technology product and need APIs integrated the right way, send us a message and tell us what you are working on.

We have been building fintech software long enough to know where things break and why. Plaid integration is a big part of what we do connecting it, scaling it, and fixing builds that were rushed the first time around. We have worked across account linking, transaction syncing, identity verification, and asset reporting for startups and established companies. Beyond Plaid, we handle Stripe, Dwolla, and full neobank development flows. We write solid code, communicate clearly, and actually finish what we start.
