About Me

Pedro Paulino Martiniano, backend software engineer focused on distributed systems and high performance. I work on the design and implementation of scalable solutions, prioritizing code quality, clean architecture, and engineering best practices. My career spans companies of different sizes, from tech startups to scale-ups like Mercado Livre, always focused on delivering technical value and collaborating with high-performance teams.

Education

Bachelor's degree in Software Engineering from Uni-FACEF, with academic distinction in four consecutive semesters and three Oracle Database certifications. Continuously evolving, currently pursuing an MBA in Software Architecture at Full Cycle School, with a focus on system design, architectural trade-offs, and technical decision-making in high-complexity scenarios.

Technical Expertise

Specialization in Golang and Python for backend system development. Solid experience in distributed systems, RESTful and event-driven APIs in microservices architectures, with a focus on security, scalability, and performance. Proficiency in SQL and NoSQL databases, as well as messaging and orchestration services. Experience with RAG applications and multi-agent systems using LangChain, LangGraph, and CrewAI. Consistent application of design patterns, SOLID principles, Hexagonal Architecture, and DDD in real-world projects.

Experience

As part of the LATAM Operational Excellence team at Mercado Livre, I work on the design and development of high-performance microservices in Golang, aiming to improve the efficiency, reliability, scalability, and quality of internal logistics processes. My work focuses on delivering robust backend solutions that support essential operational flows across multiple Latin American countries, operating in a high-scale environment and ensuring continuous improvement of the logistics ecosystem.

On the R&D team at CCM Tecnologia, I was responsible for developing and maintaining REST and event-driven APIs in a microservices environment with Golang and Node.js. I worked with messaging services and cloud platforms (AWS and OCI), applying clean code, SOLID, Hexagonal Architecture, and Scrum. Led data integration projects with Python and Pandas scripts for Cron Jobs, and developed RAG applications with multi-agent frameworks (LangChain, LangGraph, CrewAI) for generative AI solutions.

Supported the development and maintenance of REST APIs and microservices with Golang and Node.js. Participated in implementing messaging services and integrating with cloud platforms (AWS and OCI). Contributed to data integration projects with Python scripts for Cron Jobs, applying clean code and SOLID principles in collaboration with the R&D team.

Three-month development training program. Developed and maintained REST APIs with Node.js, TypeScript, and Express, applying clean code, OOP, and agile methodologies (Scrum and Kanban). Executed unit and integration tests. Additional experience with web applications using React and Next.js.
