Jorge – React, AWS, Typescript

A multi-product web ecosystem for a client, featuring two core platforms: a production-grade file management platform enabling direct, secure client-to-cloud document uploads, and a specialized medical forum with a user reward system. To support incentivized engagement and security, the forum integrates an asynchronous user verification flow to validate identities. Together, these independent platforms support complex workflows ranging from high-volume cloud file processing to identity-verified interactions within healthcare communities.

• Architected a Next.js file management platform from initial MVP to full production, designing a secure pipeline that requested presigned URLs via a Nest.js API to enable direct client-side uploads to Amazon S3.
• Engineered a robust session-refresh mechanism within NextAuth.js that eliminated token expiration errors and reduced session failures.
• Designed an asynchronous user verification system by integrating WithPersona into a Svelte.js frontend backed by Python AWS Lambda microservices.
• Adopted an agentic development workflow utilizing Cursor for rapid prototyping, planning, and TDD while maintaining engineering oversight and code quality.
• Maintained and extended a full-stack microservices architecture spanning a Svelte.js frontend and Python AWS Lambda backends.

A distributed, event-driven communication platform designed for the real estate domain, specifically automating workflows for title and escrow closing operations. The system processes high-volume closing events and orchestrates multi-channel notifications across administrative and client-facing web portals. Built around a microservices architecture with a Backend-for-Frontend (BFF) layer, the platform enables real-time data sync, targeted feature delivery via feature flags, and reliable, high-throughput event processing for complex property transaction lifecycles.

• Expanded a high-volume event-driven communication ecosystem by developing new features and message consumers within a Nest.js microservices architecture, processing title and escrow closing events via Amazon SQS.
• Scaled feature capabilities across administrative and client-facing web applications by writing optimized GraphQL queries, mutations, and resolvers within a Backend-for-Frontend layer built on Nest.js.
• Managed feature deployment lifecycles within a distributed system using LaunchDarkly feature flags for controlled canary rollouts and targeted feature delivery.
• Maintained data consistency and system reliability by debugging and extending event-processing logic interacting with DynamoDB and downstream notification workflows.
• Participated in structured code reviews, automated testing routines, and agile sprint planning sessions.

A series of full-stack mobile development initiatives delivered across two distinct clients: first, a luxury private jet booking platform, followed by a high-traffic music streaming application. The project scope spanned dual-client React Native mobile apps, Node.js/TypeScript APIs, and automated GitHub Actions CI/CD pipelines. Key technical contributions included end-to-end feature engineering, database normalization, major upgrades to the React Native core framework for App Store compliance, and UI performance optimizations using modern component libraries.

• Executed a critical migration of core React Native infrastructure from v0.67.5 to v0.7x, resolving breaking changes and unblocking Google Play and Apple App Store compliance mandates.
• Re-engineered the mobile presentation layer of a music streaming application by migrating from NativeBase to Gluestack UI, eliminating rendering bottlenecks and improving component reusability.
• Designed and deployed end-to-end CI/CD pipelines via GitHub Actions for iOS and Android, reducing manual release overhead.
• Engineered full-stack features for a private jet booking platform, managing two React Native mobile clients and two Node.js/Typescript APIs.
• Spearheaded a database normalization initiative that consolidated redundant data stores into a single source of truth and reduced API latency.
• Optimized perceived mobile application latency by architecting asynchronous data-fetching patterns and skeleton loading screens.

Core web platform and web scraping infrastructure for a high-traffic digital platform. The product ecosystem relies on automated data extraction pipelines, dynamic user web interfaces, and cloud-hosted microservices. Key focus areas included maintaining platform stability as part of an immediate-response engineering team; modernizing legacy backend services with Node.js and MongoDB; scaling file-processing capabilities using AWS cloud services; and automating infrastructure migration pipelines with Ansible to optimize global content delivery, site performance, and developer operations.

• Worked in an immediate response team, fixing frontend and backend bugs across microservices, APIs, workers, and the website.
• Developed a new file upload feature using Node.js, React, AWS services, and a MongoDB restructuring.
• Added features to the core scraping service using Puppeteer.js.
• Improved performance of multiple slow sections on the main website.
• Migrated the home website to AWS using Amazon EC2, Amazon S3, ALB, Amazon CloudFront, and Route53 with Ansible, improving response times.
• Extended the company’s Ansible repository so other teams could easily migrate services to AWS.
