Development of payment microservices using node.js and TDD practices, with a focus on delivering high-quality, scalable solutions. My technical skills in Javascript, Typescript, and C# enabled me to effectively develop and maintain these microservices, utilizing Chai and Jest for test-driven development. My contributions significantly improved the reliability and performance of the payment microservices, resulting in a 25% increase in transaction processing speed. I also played a key role in the maintenance of Kafka, Redis, streamliners, and APIs for these microservices.

Development of a health platform that connected professionals and patients via node.js applications using TDD methodologies and NestJS. My extensive experience with Docker, Docker Compose, and various databases (such as Postgres and MySQL) allowed me to consistently deliver high-quality, scalable solutions that met the needs of both professionals and patients. In addition, I effectively utilized RabbitMQ and Kafka to integrate and manage various services, and contributed to the maintenance of tools such as GitHub, Jenkins, ECS, and ECR. My technical expertise and dedication to excellence enabled me to effectively develop and maintain a wide range of complex systems within this critical healthcare platform.

Development of microservices that automated database processes using Ansible, Python, Jupyter, Pandas, Flask, and K8s. My expertise in these technologies enabled me to effectively develop and maintain a range of complex systems, ensuring the smooth operation of critical processes. In addition, I configured Prometheus and Grafana to expose metrics of running pods in Kubernetes, enabling the monitoring and optimization of key performance indicators. My technical skills and attention to detail enabled me to consistently deliver high-quality, scalable solutions that met the needs of the business.

Creation of API's for messaging platforms such as WhatsApp, Telegram, Facebook, and Instagram using Typescript. My development of data extraction and analysis crawlers using technologies such as Puppeteer, Selenium, MongoDB, PM2, Digital Ocean, AWS, Heroku, Docker, Dokku, and MySQL greatly impacted the efficiency and effectiveness of our processes. I consistently demonstrated a strong commitment to good programming practices and implemented commit patterns on GitHub to ensure the highest level of quality. Additionally, my development of API's using Python, Django, and Flask, as well as the implementation of queuing systems using RabbitMq, BeeQueue, and Bull, greatly improved the performance of our systems. My use of Elastic Search and development of charts using Kibana enhanced the searchability and visualization of data, respectively. Overall, my technical expertise and dedication to excellence enabled me to significantly contribute to the success of the business.

Creation of POS systems using Electron. My development of reliable API's using Python and Flask, and their integration with the frontend, was critical to the success of the project. I also implemented caching strategies using Redis to improve the performance of the system. In addition, I developed static pages using a range of tools such as React, VueJS, jQuery, and Websockets. I also made significant improvements to queries in the MySQL database, enabling the system to operate more efficiently. My work also included the transition of the system from a local environment to a web-based platform using NextJS. To ensure the scalability and high availability of the system, I implemented Dockerization and made improvements using NGINX and Docker. My technical skills and attention to detail enabled me to consistently deliver high-quality, reliable solutions that met the needs of the business.
