Ramiro Rivas — Software Engineer
Inventory systems, dealer quoting portals, and portfolio websites - with AI integrated where it actually earns its place. Eight projects, most running in production for real businesses, each explained down to the architecture.
A window and door dealer runs inventory and invoicing on this instead of spreadsheets - stock counts cannot drift, and the LLM assistant is never allowed to do the math.
Handles WhatsApp intake for a 550-client tax practice in English and Spanish - with a PII firewall no message can bypass, so client data never reaches a third-party API.
A Raspberry Pi camera as a touchless remote: MediaPipe hand tracking, a self-trained gesture classifier, and Wake-on-LAN over a direct Ethernet link.
A published Claude Code plugin used to ship Flutter + Supabase apps faster: 12 slash commands and 9 specialized agents covering the full mobile lifecycle.
Contractors manage clients, contracts, and payments from their phone - a production Flutter app with its own documented design system and testing playbook.
Dealers price and quote complex window configurations in minutes instead of phone calls - configuration-dependent pricing, discounts, and terms for a manufacturer's dealer network.
A bespoke, animation-heavy portfolio built for a client: architectural designer Bryan Garcia presents his selected work under the Studio 36 name.
The portfolio you are reading, treated as a project: scroll choreography, a hand-rolled canvas simulation, and walkthrough videos recorded by a scripted browser.
Three engagements I do repeatedly. If your problem doesn't fit one of these boxes, email me anyway - the boxes are for clarity, not limits.
ERP & systems integration
Dynamics 365, custom portals, legacy databases, third-party APIs. I design and build the pipelines - including the delta lanes, retry logic, and monitoring that keep them running when a batch fails at 2 a.m. Built and operated in production for a window manufacturer’s dealer network.
Typical engagement: Integration audit and remediation plan, then a fixed-scope build.
AI agents with compliance guardrails
Chatbots and intake agents grounded in your actual documents - product catalogs, compliance approvals, tax records - with architectures where PII physically cannot reach a third-party API. Bilingual English/Spanish intake is a specialty.
Typical engagement: A scoped agent live in 3-4 weeks, with a written security model you can show your compliance people.
Custom portals & internal tools
Dealer portals, quoting engines, inventory systems, contractor marketplaces - web and mobile (Flutter). Event-sourced where correctness matters, so stock counts and ledgers can’t silently drift.
Typical engagement: A fixed-scope MVP, then ongoing ownership if you want it.
Have something that doesn't fit a box?
I'm a software engineer who likes owning the whole problem: talking to the person who has it, designing the architecture, shipping the product, and running it in production. Most of the work here was built for real businesses - a window and door dealer, a tax practice, a manufacturing company - not as exercises.
I care about systems that are correct by construction: event-sourced ledgers where stock can't drift, AI agents where client PII physically cannot reach a third-party API, invariants enforced with one test each. The demos and writeups on this site go into that level of detail.
DataMorph is the studio name this work ships under - one principal, no bench. When you email, you're talking to the person who designs, builds, and runs the thing.
Stack-wise I move between Python, TypeScript, C#/.NET, and Flutter, and I'm comfortable from Raspberry Pi GPIO up to cloud deployment. This site itself is Astro, React, GSAP, and a hand-rolled canvas simulation - it's project number eight, writeup included.
