Custom Layer 2 BlockchainCustom Layer 2 solution based on Polygon zkEVM, involving extensive reverse engineering of Polygon CDK and adapting it for our infrastructure needs. Transitioned from Docker to Kubernetes with Helm for efficient deployment on AWS EKS.Key Contributions:- Reverse engineered Kurtosis CDK to run services via Docker addressing both limited documentation and the necessity of modifying source code to customize Polygon's functionality to our specific requirements.- Created a git repository to enable developers to deploy all L1 and L2 services locally using Docker or Kubernetes.- Included Kubernetes configuration files within the same repository for deploying cloud environments (devnet, testnet, and mainnet) with Helm and Helmfile, ensuring efficient and seamless EKS integration.- Developed bash scripts to simplify testing and automate the deployment of L2 rollup contracts.- Overcame documentation challenges through in-depth self-learning and reverse engineering.

Let's Ping ProjectA wallet app supporting USD, stablecoins, and select cryptocurrencies, enabling users to hold assets, receive payments, and generate invoices.- Enhanced Primetrust (Neo Bank) integration, focusing on KYC/KYB compliance and asset holding.- Built a KYC/KYB validation panel, reducing costs by intercepting invalid submissions.- Migrated business flows to Fortress after Primetrust's bankruptcy, ensuring a smooth user transition.- Integrated AWS for ID extraction and facial recognition to boost security.

Aracar ProjectA car marketplace platform enabling users to publish and sell vehicles, with integrated financing options.- Designed and implemented core features to streamline business flows and improve usability.- Set up Cron jobs for automated flow triggers (e.g., expiring entities).- Developed MySQL scripts for database structure updates.- Created a dynamic filtering service with Sequelize ORM.- Built backend integrations for chatbot access (e.g., WhatsApp, Telegram, RocketChat).

The project consisted in a main device (raspberryPi) in charge of measuring temperature and humidity of a truck's chamber. The measurements where encrypted locally for avoiding intentional data corruption. Measurments where published directly from the RasPi to a specially designed smart contract deployed at Rinkeby testnet.Each device has it's own contract created with a contract factory.

- Lead Voice control project. Voice Control architecture definition for multimedia ecosystem (remote control, set top boxes, web and mobile apps) and implementation tracking.- Lead Implementation of a VOD and Live content feed generator system for Google Search availability.

- Developed technical specifications for xDSL modems, GPON ONTs, and PLCs. -Researched solutions for device management behind NAT (TR-181). -Analyzed analytics platforms to assess QoE on home networks via TR-069 and device-embedded agents.- Conducted multivendor ONT and OLT evaluations to ensure compatibility with existing and new services (e.g., prioritized Unicast and Multicast Video).- Adapted backbone and metro networks for multicast video, unicast prioritization, and video traffic signaling during Telecom and Cablevisión merger.

Characterization MOS structures for dosimetry.MOS (Metal Oxide Semiconductor) structures were characterized that, due to their properties, could satisfactorily fulfill the function of low radiation sensor.
