Ceres en Red — Local Services Platform
Role: Fullstack Engineer & Product Owner · 2025 – Presente
Overview
Ceres en Red is the official platform of the Government of the City of Ceres to connect residents with verified professionals and technicians quickly, safely and directly. It allows finding services by category, profession or location, accessing detailed profiles and contacting the professional directly via WhatsApp, without intermediation or friction. The goal was to solve an everyday problem: when an urgency arises (plumber, electrician, nurse, lawyer), residents don't know who to contact or how to do it reliably. Ceres en Red centralizes this information, promotes local work and creates an official, validated channel between citizens and professionals.
Problem
Before Ceres en Red: residents depended on word of mouth to find reliable services; there was no official channel to validate local professionals; professionals had no centralized space to showcase their offer; search was slow, informal and not scalable. The municipality sought a solution that was simple, direct and frictionless; accessible from mobile; prioritizing immediate contact; with institutional validation to build trust.
Solution
I designed and developed a web platform where residents can search for professionals by sector, profession, city or category; each professional has a public profile with services, coverage areas, hours and direct WhatsApp contact; the municipality validates and approves profiles before making them visible, ensuring trust and quality; professionals manage their information from their own panel; contact is made outside the platform (WhatsApp), eliminating friction and need for internal messaging. The result is a local, lightweight, direct marketplace focused on solving real problems in minutes.
My Role
I was responsible for the project end-to-end: product definition, scope and roadmap; UX/UI design and information architecture; database modeling; full frontend and backend development; authentication (email/password + Google/Facebook); professional panel and verification flow; infrastructure, deployment and performance optimization; implementation of workers and jobs for emails and notifications. I acted as Fullstack Engineer and Product Owner.
Technical Architecture
Frontend / App: Next.js (App Router) · TypeScript · Tailwind CSS · Reusable components Backend / Infra: Modular internal API · Workers for emails and logs · Deployment on Vercel and containers Authentication: Email/password · OAuth (Google / Facebook) Contact: Direct integration via professional's WhatsApp (no intermediation)
Impact
Facilitate access to professional services in the city Promote local work Reduce search times in urgent situations Generate trust through institutional validation Become the base services platform of the local ecosystem
Major Challenge
Next.js build and performance optimization: as the platform grew in routes, components and assets, the build became heavy and slow. I worked on bundle optimization, strategic code splitting, lazy loading of heavy components and reorganization of layouts and dependencies. This allowed maintaining low build times and a smooth experience on mobile devices. Async jobs and processes: I implemented separate workers for email sending, log processing and system notifications. This decoupled critical tasks from the main request-response and improved system resilience.
Current Usage
Platform deployed in production. Active domain: ceresenred.ceres.gob.ar. In process of public launch. Active loading of local professionals being validated by the municipality.
