Dimitris Fakas
Dimitris Fakas is a lawyer building an app to streamline workflows for diving centers. He integrated Firma.dev's e-signature API in under 10 minutes using Replit AI, with zero development experience, and got document signing working on both web and mobile on his first try.
Not a Developer, Not a Problem
Dimitris is a lawyer based in Greece who works in the diving industry. About a year and a half ago, he started building an app designed to streamline operations for diving centers, covering everything from dive preparation and acceptance workflows to the legal and medical documents that divers are required to sign before getting in the water.
The app needed e-signatures baked in. Divers sign liability waivers, medical declarations, and other compliance documents as part of the standard pre-dive process. Dimitris needed a signing solution he could integrate into the app himself, because he's building the entire thing solo using Replit AI with no prior development background.
I'm not a dev. And this is the reason I told you that this was super easy for a guy who is totally unaware of developing a code. So yes, this is reality.

Under 10 Minutes to Working Signatures
Dimitris had Firma.dev integrated and working in under 10 minutes. He grabbed the API keys, added them to his Replit secrets, and it worked. No configuration headaches, no unexpected behavior during setup.
The signing interface works on both web browsers and smartphones, which matters for his use case. Divers at a center aren't sitting at desks. They're signing documents on whatever device is available, often a phone at the dive shop.
Take the API keys, put them in my secrets, bam. And this is what I wanted to work.

Simple Enough for Non-Technical Users
A key concern for Dimitris was how the signing experience would feel for divers, many of whom aren't particularly tech-savvy. He's been running tests with real users and collecting feedback during his testing phase.
One piece of feedback he noted: some divers assumed that drawing their signature completed the process, not realizing they still needed to click confirm and then finalize. He added a small notice to his app explaining the steps, which resolved the confusion. Beyond that minor UX note, the integration has been smooth.
Your email was straight ahead. I mean, I really appreciate this kind of communication. Precise, fast, small. I really can work with these.

No Prior Solution, No Competitor Lock-in
Before Firma.dev, Dimitris didn't have a signing solution in place. He had tried to integrate something else earlier in the build process but couldn't even recall what it was, having made roughly 10 different integrations across the app. He looked at DocuSign at some point and found it expensive, especially given that his signing volume is completely unpredictable at this stage.
Firma.dev's pay-as-you-go pricing meant he could add e-signatures without committing to a subscription he might barely use. For a solo builder testing an app that doesn't have users yet, that's the difference between shipping a feature and postponing it.
Firma.dev Was the First Greek Integration
Dimitris was Firma.dev's first Greek-language user. The team added Greek language support for his use case, which matters when your end users are divers in Greece who need to read and sign legal documents in their own language.
