Hi, I'm Gris Sunglasses emoji

Donatelo Coding

Welcome to my page!

I’m a Software Engineer with 10+ years of experience building web and mobile applications, end-to-end systems, and scalable architectures that balance UX with business goals. I combine product engineering, platform development, and technical leadership, with ownership across frontend, backend, AI/Computer Vision, product security, and delivery pipelines, especially in regulated, high-risk environments (fintech/betting).

At Legitimuz, I partnered closely with the CEO and CTO to scale the IT organization as a hands-on engineer and technical leader. I built and evolved the admin/dashboard, Web SDK, and native Mobile SDKs (iOS/Android), enabling fast, stable, well-documented integrations. I also supported client engineering teams worldwide—joining calls to unblock integration, troubleshoot issues, and ensure successful go-lives.

On the identity and risk side, I architected and implemented core KYC, integrated multiple liveness providers, and contributed to proprietary liveness technology focused on reliability, security, and low-end device performance. I led Applied AI/Computer Vision in production (OCR, document type & quality prediction, face detection/recognition, biometrics, active/passive liveness). In parallel, I contributed to fraud & abuse prevention (deepfake detection, anti-spoofing, presentation/replay defenses, injection/bypass detection, device intelligence/profiling) and compliance-driven decisioning (AML/PLD, PEP screening, geo-compliance signals), balancing conversion vs. security.

I lead by setting frontend standards, mentoring engineers, and driving quality via stronger testing and QA practices (including founding and leading QA). I also have strong business alignment across B2B, B2C, B2B2C, and SaaS, translating product strategy and compliance needs into engineering execution.

Core stack: TypeScript, React/Next.js, React Native, Node.js (Express/NestJS), Go, Python/FastAPI, AWS + Kubernetes (EKS), Docker, CI/CD, Cypress/Jest, Sentry/New Relic, TensorFlow/PyTorch.

Industries: Internet/Communication, fintech/banking, betting/regulated platforms, e-commerce, healthcare, climate tech/Carbon Credits market (ESG).
