Lexington Emilio C.

Hi there! I’m a Full Stack Developer with 5+ years of hands-on experience helping clients build robust web and mobile applications that scale. Here’s how I can add value to your project: Front-to-Back Expertise: • JavaScript/TypeScript | Node.js | Nest.js • React (web) | React Native (mobile) I design clean, modular code and maintainable architecture so your app stays rock-solid as it grows. API Design & Data Layer: • RESTful API development (Node.js/Nest.js) • PostgreSQL schema design, querying, performance tuning Whether you need a simple CRUD backend or a complex data pipeline, I’ll ensure your endpoints are reliable, secure, and fast. Web Scraping & Data Processing: • Cheerio | Puppeteer I’ve built scrapers to gather large volumes of structured data, normalize and process it, then feed it into databases or downstream services—perfect for market analysis, lead generation, price tracking, and more. Performance Optimization & Clean Architecture: I focus on identifying and eliminating bottlenecks (database indexing, caching, code-splitting) and structuring projects so they’re easy to extend. Your users will enjoy snappy load times and smooth interactions. Collaborative, Client-Focused Approach: I believe clear communication and iterative feedback are the keys to success. I’m comfortable working with designers, product managers, and cross-functional teams—and I’m always proactive about sharing progress, roadblocks, and next steps.
