I’ve been working on a waste management and sustainability platform called TrashSmart.
It’s a centralized system built for one organization to manage end-to-end waste collection operations. The platform connects registered users who request waste pickups with assigned collectors, while admins oversee scheduling, assignments, payments, and overall operations.
The system supports multiple waste types and pickup sizes, includes a structured order workflow from request to completion, and features a rewards system that encourages recycling and eco-friendly behavior. Both users and collectors earn points that can be redeemed or used as incentives within the platform.
From a technical perspective, I focused on building the full backend architecture using Firebase, including role-based access control, Firestore data modeling, authentication flows, and operational logic for orders, payouts, and rewards.
It’s been a solid build in terms of designing something that blends logistics, sustainability and incentive-driven behavior into one system.
Turning a workspace into an atmosphere makes such a difference. ✨
Love the warm lighting, layered details, and cozy mood here. It feels less like a desk setup and more like a space you’d actually want to spend hours creating in. 🔥
Technical performance engineering and Core Web Vitals optimization for comoimportarmicoche.es.
Achieved 92+ performance scores on mobile alongside 100/100 ratings in SEO, Best Practices, and Accessibility on a live production WordPress site by streamlining front-end asset delivery and eliminating backend execution bottlenecks.
Key Engineering Highlights:
• Asset Optimization: Minified, combined, and deferred non-critical CSS/JS, significantly reducing render-blocking resources and critical path latency.
• Next-Gen Media Pipeline: Implemented WebP image conversion, explicit aspect ratio dimensions to eliminate Cumulative Layout Shift (CLS), and native lazy-loading.
• Clean Architecture: Optimized dynamic database queries and custom PHP scripts to maintain near-instant Server Response Time (TTFB) without relying on heavy caching plugins.
• Core Web Vitals Targets: Focused on Largest Contentful Paint (LCP) and Interaction to Next Paint (INP) to deliver sub-1.5s real-world loading times on mobile devices.
Yeah, this was a cold run in PSI. The DB cleanup was actually huge for TTFB—dropped uncached server response under 200ms, mostly by clearing bloated wp_options and fixing custom loops. Caching handles repeat hits, but the backend fix was the main win.
