Architected and optimized TypeScript, React, Node.js, and Python services for large-scale media, advertising, commerce, and search workflows. Built React/Rust/Wasm interop, real-time bidding services, event-driven merchant notifications, checkout integrations, streaming search experiences, and recommendation microservices backed by SageMaker and OpenSearch.

Delivered cloud-native AWS solutions using ECS, Lambda, S3, DynamoDB, PostgreSQL, Redis, CloudFront, Docker, Kubernetes, and CloudWatch. Improved UI frame times, bid-response latency, inventory synchronization reliability, merchant conversion, bandwidth efficiency, search freshness, and CI/CD rollback reliability through performance engineering, canary releases, automated monitoring, and resilient service design.

Developed and modernized mobile banking and financial platform capabilities using React Native, TypeScript, Node.js, GraphQL, PostgreSQL, Redis, and Python. Rebuilt client state management, implemented feature-flag platforms, created Open Banking normalization layers, and developed fraud-detection services with real-time internal alerting.

Strengthened security and reliability through PCI-DSS audit pipelines, OAuth2 PKCE, MFA, secure device token storage, session invalidation, and multi-region ECS/Fargate deployment. Built WebRTC onboarding infrastructure with coturn and AWS, optimized GraphQL and database performance, and established telemetry and SLO dashboards for video-call quality.

Modernized financial reporting and portfolio-management platforms for banking clients by migrating legacy .NET and SQL Server systems to Python/Django microservices running on AWS ECS. Built Node.js and TypeScript market-data ingestion services with Kafka and Redis, as well as Angular-based portfolio analytics portals for high-volume client asset data.

Designed multi-tenant PostgreSQL architectures, optimized queries and indexes, integrated SWIFT, ACH, PSE, and core banking APIs, and automated delivery with Jenkins, Docker, and AWS CodeDeploy. Improved deployment reliability, API latency, reporting speed, test coverage, and engineering velocity while mentoring junior developers and supporting regulatory compliance.

Developed and maintained high-availability full-stack applications for financial and insurance clients using Python, Django, JavaScript, PostgreSQL, Angular, and React. Built REST APIs, SOAP integrations, reporting modules, data-normalization layers, interactive dashboards, D3.js visualizations, and PDF/Excel export capabilities.

Improved scalability and delivery by migrating on-premise workloads to Docker services on AWS, optimizing PostgreSQL and MySQL databases, implementing OAuth2 and JWT authorization, and automating deployments with Jenkins and Ansible. Established automated testing, production monitoring, agile delivery practices, and internal knowledge-sharing sessions on Python, Docker, and API design.

Bachelor's degree in Computer Engineering completed in Bogotá, Colombia.
