Summary

Software architecture, DevOps, web scraping, data extraction, and mining, with a strong emphasis on eID (Electronic Identification) and KYC/KYB (Know Your Customer/Know Your Business) solutions.

At Attestto, I played a pivotal role in the development of the Citizen ERP+ system, where I led the design and implementation of secure user authentication, credentials management, and privacy-focused features.

I successfully integrated passwordless authentication using webAuthn, ensured secure data access with ACLs, and designed transactional screens in Laravel. Moreover, I integrated Web3 technologies, specifically Solana, into the ERP system to enable seamless accounting, invoicing, and online payment functionalities.

I have extensive experience in working with APIs and web services, including integrations with Stripe Connect & Circle, and extensive research for Wise, Plaid, ACI worldwide, LEI (GLEIF), and SWIFT, as well as for eID solutions using Decentralized Identifiers (DIDs) and W3C Verifiable Credentials (VCs) for secure distributed credentials.

Leveraging tools like Tesseract, Tensorflow.js, MediaPipe.js, and the OpenAI API, I incorporated advanced features such as computer vision and machine learning pipelines. Overall, my work at Attestto involved driving privacy, security, and cutting-edge technology integration within the Citizen ERP+ system.
