Lucas Ciucini

I collaborate on the design and development of cutting-edge, AI-driven solutions, specializing in data analysis, image generation, chatbots, and advanced system integrations. I leverage technologies such as LangChain, LangGraph, LangSmith, and Langfuse, using Python and Node.js to deliver scalable, high-impact products. I design robust infrastructures for high-demand systems and asynchronous microservices workflows, and I mentor/support frontend teams to refactor legacy codebases and build scalable React applications from scratch. I also build and maintain CI/CD pipelines using GitHub Actions and deploy services on Google Cloud Platform (GCP).

Led the end-to-end redesign and rebuild of the IRIS Virtual Assistant frontend from scratch using React and TypeScript, aligned with modern UX and accessibility best practices. Modernized the monorepo by introducing Turborepo, defining repository structure, build strategy, caching, and developer workflows to improve speed and maintainability. Migrated and consolidated shared libraries (UI components, utilities, types, tooling), reducing duplication and improving consistency across apps and packages. Implemented and maintained scalable Node.js/TypeScript microservices and APIs to support new product features and integrations. Improved asynchronous, event-driven workflows by enhancing a Pub/Sub-based microservices architecture to increase decoupling, reliability, and throughput for background jobs. Integrated AI capabilities (OpenAI/GPT models) into the conversational platform to enhance customer support experiences and improve response quality and consistency. Collaborated on the integration of WhatsApp as a new communication channel, enabling multi-channel conversational responses and extending the assistant’s reach. Partnered with platform and security teams to strengthen deployment, monitoring, and operational practices on Google Cloud. Coached and onboarded new team members through pairing sessions, code reviews, and best-practice guidance, raising team autonomy and delivery quality.

Participated in the creation of a dApp for the PWBS2022 event, where the world's first NFT flight auction took place. Achieved the integration of Web3 JS with Metamask, enabling user interaction with app offers and auctions. Integrated Onfido's KYC service into our platform, automating processes and creating a tool stack for the operations department to intervene in manual review cases. Part of the team that created a Node JS API for User Registration, Login, Subscription, Unsubscription, and KYM. We also created a microsite with Next JS, Material UI, and Typescript to handle KYC, registration, and login processes, using Cognito for user management. Collaborated in the creation of micro frontends such as the header and footer, minimizing library dependency and enabling branding changes with the arrival of new clients without requiring a full app deployment. Participated in the creation of a Node JS API and a backoffice micro frontend to manage the configuration of various UIs, implementing the Server Driven UI paradigm. This implementation allowed a more agile integration of new clients. Collaborated in the creation of a backoffice with a microfrontend architecture, integrating the backoffices of Server Driven UI, users, and KYC. This architecture was designed to allow each team to add their own administration panel independently, avoiding the need for a blocking deployment to update.

Worked with the client Morfurniture https://www.morfurniture.com, a major e-commerce specializing in online furniture sales, with augmented reality integrations for home previewing. The platform was built using Next JS with React JS and a proprietary UI framework, with Strapi for user management. Leveraging my experience in mobile development, especially iOS, I was able to collaborate in improving the experience on these devices and in the development of new features.

Olpays was a startup aimed at creating a white label payment gateway. In it, I mainly served as a backend developer, creating various features for two large APIs, one for payments and one for withdrawals. Developed multiple microservices responsible for calculating fees, releasing payments, and releasing funds, using Node.js, Express, MongoDB, RabbitMQ, and Docker. Integrated an anti-fraud platform called Sift Science, strategically applying blocking rules to prevent the use of stolen or cloned cards and detect patterns of fraudulent users. I also collaborated in the design of the user experience of the backoffices to manage these payments and withdrawals.

SUR Technology is a consulting firm that offers end-to-end solutions, from concept and strategy, to design, implementation, and support. The success of our clients helps us to be the leader in the marketplace. At SUR Technology, every project is important; we combine industry knowledge and the best technical resources in the world. I was in charge of the development of a Virtual Wallet with a BLE card reading system with an external device, developing a plugin for Ionic technology with which the app was created. We created a management application for therapists providing services to a health company. I worked on integrating administration panels focused on debit card issuance and POS management, incorporating Angular JS and React into the existing .NET technologies. I collaborated on a ticket sales platform, implementing functionalities in both the user interface and the administration panel.

In the early stages of my career, I worked as a freelance developer, using Content Management Systems (CMS) such as Joomla and WordPress to develop websites.
