Security and performance are part of the work
Working on banking dashboards taught me that RBAC, JWT details, and Lighthouse scores are easier to handle while building a feature than to revisit later.
I build secure, fast, and accessible digital products across web, mobile, and desktop. Over the last seven years I've shipped e-commerce, banking loyalty systems, backoffices, and business platforms — always with a focus on performance, security, and user experience.

Front-end Developer
BairesDev
- Redesigned and improved the UX of enterprise web applications using React, TypeScript, Redux, and Vite, delivering high-performance interfaces aligned with accessibility and Core Web Vitals targets.
- Integrated AWS services — Cognito for authentication, DynamoDB for persistence, and Lambda for serverless compute — to power secure, scalable features in production.
- Built serverless full-stack capabilities with AWS Amplify, shortening deployment cycles and reducing infrastructure overhead.
- Collaborated daily with cross-functional teams (product, design, backend, QA) through Agile ceremonies, pull-request reviews, and asynchronous communication in English.
- Enforced code quality with ESLint, Prettier, unit tests via Jest and React Testing Library, and Git-based release workflows.
Front-end Developer
Publipromueve S.A.
- Built and maintained administrative platforms and loyalty reward systems for major Ecuadorian banks, handling sensitive financial data under strict security and compliance requirements.
- Implemented role-based access control by decoding JWT claims, enforcing permissions at the route, view, and component level across multiple backoffice products.
- Delivered consistent performance gains measured against Lighthouse and Core Web Vitals reports, reducing bundle size, image weight, and time-to-interactive on banking dashboards.
- Promoted features through development, staging, and production environments with disciplined release testing, lowering post-release defects and security incidents.
- Shipped features with React, TypeScript, Node.js, Material UI, Axios, React Hook Form, Recharts, and date-fns; upgraded library versions safely without breaking existing UI contracts.
Full-Stack Developer
Address Search Field
- Designed and published an open-source Flutter plugin (Dart) that provides global address autocomplete via the Google Places API, with geocoding and directions integrations.
- Implemented native iOS (Swift) and Android (Kotlin) method-channel bridges to expose location-aware functionality through a clean Flutter API.
- Maintained semantic-versioned releases with documentation, examples, and tests, supporting adoption by mobile teams worldwide.
Full-Stack Developer (Freelance)
Taxi Green
- Built a complete taxi-service platform end-to-end as an independent developer, including two React Native mobile apps (rider and driver) and a web administrative backoffice.
- Implemented real-time vehicle location tracking, ride request routing, and dispatch management with WebSockets (Socket.io) and Google Maps SDKs.
- Designed the initial backend on Firebase (Auth, Firestore, Realtime Database, Cloud Functions, FCM) and later migrated to Node.js + Express + GraphQL (Apollo Server) as scale and query complexity grew.
- Integrated Google Places, Geocoding, and Directions APIs to deliver accurate route assignment, ETAs, and pricing.
- Shipped trip-history, financial reporting, and role-based dispatch tools in the React backoffice, including data exports and visualization.
Full-Stack Developer
Codecworld S.A.
- Designed and shipped backend services for the management of clients, policies, and financial transactions in insurance products, written in Laravel (PHP) and Spring Boot (Java).
- Led backend development of a facial-recognition system for the Ecuadorian National Police, exposing a Python deep-learning model through a REST API consumed by a React front-end.
- Optimized SQL queries and request performance on a high-traffic travel-ticket purchase platform built with Yii2, lowering checkout latency and database load.
- Implemented cached JWT-style token handling backed by Redis to reduce repeated identity-provider round-trips and unnecessary front-end loading states.

Volunteer Developer
PUCESE
- Co-developed a marketplace mobile app for buying and selling products as part of a university volunteer initiative, focused on onboarding and usability.
- Built the React Native front-end and the Firebase backend (Auth, Firestore, Storage, FCM), wiring real-time listings and push notifications.
Developer Intern
EP FLOPEC
- Maintained internal computer infrastructure in the Systems department, ensuring availability for daily operations.
- Built and maintained an internal inventory-management system with Laravel (PHP) and MySQL, including reports and asset tracking.
- Delivered an employee-suggestion module in Vue.js integrated with the corporate Active Directory through LDAP authentication.

A few habits I try to keep while building software.
Measure before optimizing
I like to lean on Lighthouse, SQL profiling, and bundle analyzers to find where the slow paths actually are, rather than guessing.
Start with the smaller version
Sometimes Firebase is enough for a while; other times the project really needs Node and GraphQL. I try to make that call when the context asks for it, not before.
Look for the root cause
When something breaks I prefer to reproduce it, isolate the variable, and verify the fix. Quick patches tend to come back later.
