Certainly | Jun 2023 - Present

Software Engineer

Building intelligent chatbot solutions at Certainly has been an engaging journey, fueled by innovation and a commitment to excellence. My role entails: Designing and Developing AI-Powered Chatbots: Collaboratively working with my AI and product colleagues, we utilize a range of AI tools, including NLP and LLMs, to create conversational agents that engage users and deliver meaningful interactions and craft robust solutions that are scalable, maintainable, and responsive to our chatbot's needs. Django: Sustain robust backend systems, managing data and business logic for our chatbots. Conversational Logic Creation: Using NLU and LLMs, I we refine the conversation flows, ensuring our chatbots understand user intents and respond appropriately, all while adapting to the diverse needs of our clients. Maintenance: Ensuring our backend systems are running optimally and free from issues is key. We regularly perform refactors, optimizations, and updates to maintain a high level of operational efficiency. Joining the team as a backend developer after a tenure in QA has provided me with a unique perspective. I leverage this experience to ensure our backend systems not only perform well but also meet the stringent quality standards our users have come to expect from us.

Certainly | Oct 2022 - May 2023

Lead QA Engineer

Defining the QA process for Certainly is a big challenge that we're going through with enthusiasm! This process involves a lot of detail, including: - Define and describe the current existing features along with the CTO and Ideation team - Setting up valid datasets to test, this includes working with LLMs, NLU setups, Prompt engineering with chatGPT - Manually test the features through different testing paths using the previous data. This is a big challenge since the conversation flow of a bot is very diverse and depends on each client - Organizing everything in Azure DevOps. This includes tests, validation tasks, bugs, even PBIs(user stories) development We also go through the automation process using playwright with typescript using page object model and BDD, having the tests ready for every release as new features are developed. We do API testing using Karate to test our Chat API, LLM API, NLU training and dataservice API. We do load tests with Gatling (Moving to Locust) to ensure our services scale properly on demand. The QA process also includes managing the release. We define which tasks are ready to be promoted from staging, to the preproduction environment, and finally to production. From QA we analyze commits to make sure there's no piece of untested code going to production, we deploy the tested services and make sure they work as expected on production. We also are in direct contact with CS, making sure they get constant feedback on what they do, if they find bugs, or if something is not working for a client. This is of course an ongoing process and is evolving on demand, as needed from the developer side or from the business side.

Dimática Software Development | Oct 2020 - Jan 2022

QA Engineer

Putting together all my experience in IoT, SCADA systems and construction sites, I test, improve and develop an IoT web platform that lets construction site workers obtain live and historic data from different sensors present in a construction site. This includes: - Manual testing of the platform using CrossBrowserTesting - API testing using Karate - Performance testing using Gatling - Automated frontend tests using Playwright - Software Architecture analysis - Database testing Postgre/Mongo - Hardware analysis for the different sensors - Analysis of the different communication protocols (like MQTT, Modbus or HTTP protocols) - Develop User Stories using BDD under Gherkin syntax - Using JIRA under SCRUM

GRUPO VIARIUM | Jun 2018 - Sep 2020

Project Engineer

Viarium Technology Development is the new branch of Viarium Group, working in the implementation of new technologies in classic and modern engineering projects. This implies the development of classic projects for international public and private entities, dealing with hardware and software providers, service providers and dealing with all the logistics involved in an end to end project. In this sense, Viarium Technology Development acts as an integrator, merging various technologies, hardware, software and services into a functioning high complexity project to the end user. Between the most developed technologies in Viarium we have Smart Parking, measuring of environmental parameters, geolocation, classified tech projects, automation, IoT, communication protocols, APIs, GIS technologies, and everything related to modernization of buildings, from ports, airports, to parking lots and street parkings. In my specific case I have the capacity and the goal to develop with a team, make it internal or contracted, the solutions that the client needs. I work with m2m protocols, including cloud and edge computing locations. Besides that, we do API implementations using AWS and Python (API gateway - EC2 - S3- RDS) and also, of course, generate all the documentation necessary to meet project needs.
