Hi, I'm Edgar. I design systems on SAP BTP and take them to production, and I still write the hard parts myself. 17+ years, from Mexico, on US and European hours.

If you are wondering whether I can take something on: yes, as a scoped project, as an architect on your team, or in a full-time remote role.

render<ProblemDeck cases={6} />

Here are six, in the words the client used when they brought each one to me. What I did, what came of it, and what my part was. Where a number belongs to a team, it says so.

<ProblemDeck order="as told" />rendering

01 / 06offline-first SAPUI5

We have tried three times to get this app into production.

2015 · Gentera, microfinance, Mexico

What I did: An offline-first SAPUI5 app for credit origination in the field. It worked with no signal and synced when the agent was back in coverage.
Result: It reached production on the fourth attempt, ours, and 14,000+ field agents used it.
My part: Sr. Mobile Platform Consultant at Nubaj: the offline-sync design, written up later on my blog.

02 / 06computer vision · in production

Converting one catalog takes us six weeks.

2025 · a global automaker, spare-parts catalogs

What I did: Computer vision (Keras, EasyOCR) reads callouts and part positions in the drawings; post-processing converts each catalog from the European standard to the American one.
Result: A catalog now takes one week. In production since 2025. Delivered in about three months, against the six the key user had planned.
My part: Architect, the client's main contact and project manager, and developer when the project needed one.

03 / 06SAP CAP · Build Work Zone

A supplier portal means SAP Ariba, and Ariba is too expensive for us.

2024 · a retail chain in Mexico

What I did: A supplier portal on SAP CAP and SAP Build Work Zone, with Cloud Connector to the SAP backend and Identity Authentication.
Result: 500K invoices a month from 1,000+ suppliers, at as little as a fifth of what Ariba would have cost to implement and run. Figures from the client case Cogent IBS presented at ASUG Chicago, 4 Nov 2024.
My part: The architecture and two of the modules, with Alfonso Monroy.

04 / 06Business Rules · workflows

Approvals take 20 days, and only IT can change the rules.

2019 · Delivery Hero, Berlin

What I did: Business Rules on SAP Cloud Platform, so the functional teams own approval steps, assignment and thresholds without a ticket to IT; then the project-approval and CAPEX workflows.
Result: Approvals went from 20+ days to 2. That figure belongs to the Finance Systems team, which won the SAP Innovation Award 2019 ↗ (Process Innovator). I joined in April 2019 and built the rules and the two workflows on top of the framework the team had already shipped.
My part: SAP Fiori and Cloud Platform Developer, directly contracted by Delivery Hero.

05 / 06Node.js over RFC

We need Node.js to talk to SAP.

2017 · a US window manufacturer

What I did: A Node.js connection to SAP over RFC, through SAP's own Node.js connector, before CAP existed.
Result: Live since 2017, still in use in 2026.
My part: Technical Team Lead at Cogent IBS.

06 / 06OCR · Oracle UCM

The platform has no documentation.

2008 · IMPI, Mexico's industrial property office

What I did: Our OCR project had to integrate with Oracle UCM, whose web services came with no documentation. I found the one page on the internet that explained how to switch them on: an HTML table, saved in the right place.
Result: The services ran, and the pipeline indexed 80M+ records for public access. A team result.
My part: Developer at Qualitas, in my first job.

readoffers.md2 offers · no public price

render<Offers />

Three ways: a scoped project, an architect on your team (by the hour or the month, directly or through a consultancy), or a full-time remote role.

For projects there are two offers, both scoped before they are priced. Each starts with a 25-minute call, and fees are quoted per scope once we both understand it.

<Offers count={2} />rendering

01

Build

A scoped project on SAP BTP.

Custom development with CAP and Fiori, automation with SAP Build, and integration with S/4HANA or ECC through Cloud Connector, Work Zone and Identity Authentication. I design it, lead the team and write code. You get a working system in your landscape, with tests, documentation and a handover to your people.

Proof: The supplier portal, the catalog solution, version 1 of the CI Accelerator on SAP Store ↗, Business Rules and workflows at Delivery Hero.
Starts with: The system, what it has to do, and by when. I come back with the questions that decide the design, then a first approach.

02

Agent assessment

One week. For an agent that is stuck between demo and production.

You already have an agent, on Joule or anywhere else. I review it as an architect. You get a written report: what works, what fails on your real cases, and what I would change first, in order.

scopeaccessbusiness logictest cases, present and missingcost per run

Needs: A call with the owner and one functional expert, then read access to the agent and a sample of its runs, under NDA, after we agree the scope.
Based on: 17 years of taking systems to production, and the agent work under AI on SAP: a prototype, an open-source agent and talk CT1106 at SAP TechEd 2026.

Not a fit

Keeping systems running (Basis, upgrades, support queues), configuring standard modules, or selling licenses. I design and build what the functional team defines, on SAP BTP, and outside SAP when the problem needs it.

One AI solution in production. Agents in progress. I keep the two apart, because the gap between a working demo and a system someone signs off on is most of the work.

<AIStatus honest />rendering

In production

What: The spare-parts catalog solution for a global automaker: computer vision (Keras, EasyOCR) reads callouts and part positions, post-processing converts each catalog from the European standard to the American one.
Since: 2025. A catalog takes one week instead of six.
One decision: The model kept reading the codes at the foot of each sheet as callouts. The team wanted to fine-tune it. I had the strip cropped out before recognition, and the errors went away.

In progress

Prototype: A claim-checking agent, built with a media company in Mexico: an editor approves every result, and a governance screen logs each decision and the rules frozen so far. Working demo.

Production means

Real data in the client's landscape
A person reviews the output
Monitoring and evaluation on every batch
Written sign-off by a named person
At least one real batch processed

how-i-build.md

How I build now. On my own projects and on the repo below, Claude Code and Codex draft the code and the first version of the tests. I write the spec and read every diff before it merges. Early on the agent lost context in long sessions and rewrote or deleted code that was already good; one session per task, a navigable agents.md and unit tests on every change fixed most of it. What goes to a client's landscape is reviewed by me, line by line.

Talk

CT1106 · Zero token architecture for Joule Agents

SAP TechEd Berlin · Tue 27 Oct 2026 · 14:00 CET · 20 min

Let the agent work out the first cases. What it validated becomes a playbook or code that a named person signs, and from then on that case runs without a model.

Talk notes

Open source

zero-token-joule-agents

SAP CAP + LangGraph.js · Node 22+ · MIT

An agent that stops calling the model for the cases it has already learned, and measures how much of its traffic still needs one. SAP Joule calls it over A2A.

Seventeen years in enterprise software, most of them on SAP.

I started in 2008 on an OCR pipeline for a public office, moved to SAP integration and ABAP in 2010, and have worked on SAP's cloud stack since 2015: SAPUI5, then Cloud Platform, then CAP and BTP. I have led distributed teams across India, the US, Mexico and Argentina, up to 16 people between developers, QA and project managers; today the core team is four.

On a project I am usually the architect, the person the client calls and, when it is needed, the developer. Most of what I know I learned in front of a specific problem. When I meet one I have not solved, I research it, try it on something small and then apply it. That is how I am learning agents now.

I do not commit to a date before I understand two things: who owns access to the systems, and how far the scope goes. Most of the delays I have seen in 17 years came from one of those, not from the code.
