Jesús Rodríguez

Design engineer and full-stack developer. I design the interface and build the system behind it.

A note on this portfolio

Almost everything I build lives behind another company's login.

Most of my work sits inside custom platforms built for companies: ERPs, operations tools and systems that hold client data. They are internal, so I can't publish links, code or full walkthroughs.

What you'll find here are screenshots from demos, beta releases and final versions of those platforms, plus a few concepts and products of my own. It isn't a set of polished case studies. It's an honest sample of what I've built, with sensitive data kept out of frame.

If something catches your eye, I'm glad to walk you through the context, decisions and architecture behind it.

Projects

Sierra Nexus

ERP for a textile plant

Custom inventory and operations system for a knitting and dyeing plant. It covers roll-level quality control, yarn imports, warehouse movements, Kardex auditing, finished-goods transfers and dispatch instructions. Screenshots come from the development environment.

FrameFlow

AI-assisted video post-production

Platform for post-production teams. It transcribes footage, suggests clips with viral potential using several language models (Grok, DeepSeek, Gemini) and organizes the work in four stages: planning, editing, review and approval, and assignment. It has internal comments and roles for owners, producers, editors and clients.

Red Bull Batalla

Query agent for freestyle battle data

Assistant that answers questions about battle history: each MC's stats, results and event brackets. An orchestrator classifies intent, runs atomic tools against the database and splits the answer into text and visual artifacts, such as a tournament bracket. Every answer exposes its process chain with the time spent on each step.

Aetnis

Redesign of a textile traceability SaaS

Redesign proposal for a platform that traces textile production across tiers, from raw-material extraction to finished product. It includes the traceability center, the activity timeline with its documents, workflow templates, evidence export and the product landing page.

Quester

Personal, engineering and content workspace

One workspace with three areas: personal (tasks and notes), engineering (docs, pull requests, initiatives, projects, issues and sprints) and content (a posting calendar per brand and social network).

Personal finance

Multi-currency, built for Venezuela

Finance app for the Venezuelan economy: bank, crypto and cash accounts; records in dollars with their bolívar equivalent; per-item breakdown of each purchase with VAT; recurring payments, goals, budgets and debts.

Wellness App

Wellness app for coaches and nutritionists

App for fitness and nutrition professionals who sell plans and memberships. The design covers sign-up with validation, an onboarding that calculates calorie needs, the professional's profile with Pro content, subscriber chat, community channels and a meal-plan builder with macros.

MCP Studio

Test bench for MCP servers

Desktop app to connect, inspect and test MCP (Model Context Protocol) servers. The screenshot shows an internal server with 18 tools that give a coding assistant the team's standards: it scaffolds pages, forms and backend entities, and audits components against those rules.

Interactify

Site, design and email builder

Concept for the Interactify suite, a link-in-bio platform for content creators: site builder, design creator with own and Unsplash images, email designer and social calendar. The text, color, shape and image panels share one component system.

Reminders

Scheduled messages to contacts

Prototype to schedule messages to one or more contacts, repeating weekly or yearly. Each reminder can carry several messages, such as a class notice with its Meet link and a payment note.

High-fidelity mockups

Standalone screens from several projects

Pieces that don't add up to a full case study but show how I approach specific screens: analytics for Since, 75" displays for a textile plant's knitting floor, cost and production charts, and pages for a course platform.
