About Daniel Nascimento

Experienced Software Developer with 23 years of experience and background in developing, scaling, architecting, securing, and maintaining large-scale web applications, micro services, and APIs in highly critical environments, serving millions of users daily, for the financial, healthcare and telco industries.Technologies:- Java / Kotlin / C# / Golang / React.js / Vue.js- Spring boot, Spring Cloud, Spring Security, Spring Batch, JPA, Micronaut- Microservice / Clean Architecture / SOLID / Design Patterns- AWS / GCP- Docker / K8S- Postgres / MySQL / Oracle / SQL Server / MongoDB - Kafka / RabbitMQ / AWS SQS / AWS SNS / Cloud Pub/Sub- Tests (unitary / integration / E2E)- CI/CD (GitLab / GitHub / Jenkins)I consider myself a passionate problem solver and helping people is what motivates me. My focus is to deliver and add value to the company and product, despite any tech preference. I strongly believe that we must use the right tools to achieve success in our deliverables instead of using what we know. And if I do not know the best tool or approach to deliver it I would do my best to quickly learn something new to achieve the proposed goals.Working in a diverse and multicultural team is very important to me. We learn with each other on a daily basis and get better prepared to surpass any company goals each sprint. As a leader I strongly believe in the servant leadership style and I’m always pushing hard to learn and use my knowledge to inspire people and help everyone to achieve further paths in their careers and goals. A hands on professional that will always do whatever it's possible to make it happen: removing blockers, doing PoCs, discussing business requirements with stakeholders and always trying to facilitate the daily routine.In the past years I spent most of my time building 0 to 1 products, and working with unknown and ambiguity scenarios is something that I really love. I always try to learn and improve as fast as possible, my motto is "move fast and break things" and through this mindset I always build, test and deliver the best experience with focus on generating revenue.Feel free to keep in touch at dpnascimento@hotmail.com or +55 51 99991-7066
