Throughout my career, I have specialized in scaling distributed platforms, driving architectural modernization, and mentoring engineering teams to achieve high performance and reliability. I am passionate about delivering resilient, secure, and user-centric solutions that support millions of users and mission-critical operations. My expertise spans multiple programming languages including Java, Python, Scala, JavaScript/TypeScript, Ruby, Go, and C#. I have extensive experience working with modern technologies such as Spring Boot, J2EE, Django, Flask, Node.js, React, Kubernetes, AWS, Azure, and GCP. I am skilled in building microservices architectures, deploying machine learning models in production, and optimizing system scalability and performance. At Teladoc Health, I have been instrumental in creating and scaling polyglot microservices that power AI transcription, referrals, and care delivery for millions of members. I have deployed predictive ML models that significantly improved patient engagement and health outcomes. My work involves building real-time data pipelines and leveraging cloud platforms to enhance clinician workflows. Previously, at PayPal, I developed a fraud detection engine that reduced fraudulent transactions by 35% and designed RESTful APIs to support over 10 million daily transactions. I also enhanced front-end applications to improve user experience and checkout completion rates. At eBay, I engineered AI-powered services and modernized API platforms to support billions in gross merchandise volume. I am committed to continuous learning and applying best practices in software engineering, agile methodologies, and cross-functional collaboration. I enjoy mentoring colleagues and driving technical leadership to deliver impactful solutions. I am eager to contribute my skills and experience to innovative projects that improve user experiences and operational efficiency. ## Skills 27 capabilities[Angular](https://jobicy.com/talent/angular.md)[AWS](https://jobicy.com/talent/aws.md)[Django](https://jobicy.com/talent/django.md)[Docker](https://jobicy.com/talent/docker.md)[Express](https://jobicy.com/talent/express.md)[Flask](https://jobicy.com/talent/flask.md)[Grafana](https://jobicy.com/talent/grafana.md)[Hibernate](https://jobicy.com/talent/hibernate.md)[Java](https://jobicy.com/talent/java.md)[JavaScript](https://jobicy.com/talent/javascript.md)[Kubernetes](https://jobicy.com/talent/kubernetes.md)[Machine Learning](https://jobicy.com/talent/machine-learning.md)[Microservices](https://jobicy.com/talent/microservices.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[MySQL](https://jobicy.com/talent/mysql.md)[NLP](https://jobicy.com/talent/nlp.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[Python](https://jobicy.com/talent/python.md)[React](https://jobicy.com/talent/react.md)[Redis](https://jobicy.com/talent/redis.md)[Ruby on Rails](https://jobicy.com/talent/ruby-on-rails.md)[Spring Boot](https://jobicy.com/talent/spring-boot.md)[SQL](https://jobicy.com/talent/sql.md)[TensorFlow](https://jobicy.com/talent/tensorflow.md)[Terraform](https://jobicy.com/talent/terraform.md)[TypeScript](https://jobicy.com/talent/typescript.md)[Vue](https://jobicy.com/talent/vue.md) ## Experience Career history ### Staff Software Engineer · Teladoc Health Jul 2022 – PresentCreated and scaled polyglot microservices (Java, Node.js, Ruby, React) for high-availability SaaS, powering AI transcription, referrals, and care delivery across thousands of clients and 93 million members.
