# Senior Software Engineer Location[Colombia](https://jobicy.com/resume-region/colombia.md)Rate, USD Not specifiedWork schedule Full Time, Contract, Links Language skills English, SpanishAvailable for Hire Yes Hire me Save Log in to save * ## About me I am a Senior Software Engineer with 5+ years of experience building and shipping scalable backend, cloud, and machine-learning systems for fintech and health-tech companies. I specialize in AWS, Python, Java, and modern distributed architectures, and I enjoy working on systems that need both strong engineering rigor and measurable business impact. I have led and contributed to event-driven microservices, regulatory-grade data pipelines, and production ML solutions. My work has included backend services, real-time APIs, WebSockets, data modeling, ETL pipelines, and cloud infrastructure across AWS, Docker, Kubernetes, Terraform, and CI/CD environments. I am also a co-founder and technical lead of a live credit-risk analytics SaaS product. In that role, I own the full stack end-to-end, including backend services, a React/TypeScript frontend, AWS infrastructure, and deployment automation. I focus on reliability, determinism, performance optimization, and scalable architecture. In my recent roles, I have built automated regulatory reporting systems for a major Latin American investment bank and production ML systems for health-insurance claims prioritization. I have worked on high-volume data processing, model evaluation, calibration, and systems that must remain accurate, fast, and auditable in production. I am comfortable working across the stack and across the lifecycle of a product, from architecture and implementation to testing, deployment, and monitoring. I have experience with Python, Java, TypeScript, FastAPI, Spring Boot, React, PostgreSQL, AWS services, and machine-learning tools such as CatBoost, XGBoost, PyTorch, RAG, and LLM-based workflows. I am based in Bogotá, Colombia, and I am open to remote opportunities with US/EU overlap. I speak Spanish natively and English at a C1 level, and I am looking for roles where I can contribute to backend engineering, cloud systems, and applied machine learning. ## Professional area ### [Developer & Engineer](https://jobicy.com/resume-category/dev.md) ## Skills ### [AWS](https://jobicy.com/resume-skill/aws.md)[CI/CD](https://jobicy.com/resume-skill/ci-cd.md)[Docker](https://jobicy.com/resume-skill/docker.md)[Express](https://jobicy.com/resume-skill/express.md)[Full Stack Development](https://jobicy.com/resume-skill/full-stack-development.md)[Git](https://jobicy.com/resume-skill/git.md)[Java](https://jobicy.com/resume-skill/java.md)[JavaScript](https://jobicy.com/resume-skill/javascript.md)[Kafka](https://jobicy.com/resume-skill/kafka.md)[Kubernetes](https://jobicy.com/resume-skill/kubernetes.md)[Machine Learning](https://jobicy.com/resume-skill/machine-learning.md)[Microservices](https://jobicy.com/resume-skill/microservices.md)[Monitoring](https://jobicy.com/resume-skill/monitoring.md)[MySQL](https://jobicy.com/resume-skill/mysql.md)[NLP](https://jobicy.com/resume-skill/nlp.md)[PostgreSQL](https://jobicy.com/resume-skill/postgresql.md)[Python](https://jobicy.com/resume-skill/python.md)[React](https://jobicy.com/resume-skill/react.md)[Regulatory Reporting](https://jobicy.com/resume-skill/regulatory-reporting.md)[Spring Boot](https://jobicy.com/resume-skill/spring-boot.md)[SQL](https://jobicy.com/resume-skill/sql.md)[SQL Server](https://jobicy.com/resume-skill/sql-server.md)[Terraform](https://jobicy.com/resume-skill/terraform.md)[TypeScript](https://jobicy.com/resume-skill/typescript.md)[Vue](https://jobicy.com/resume-skill/vue.md) ## Education 2019 B.Sc.
