What I built for clients, and what I built for myself
Magistral CRM
Magistral Constructora
The CRM an Arequipa construction company uses to receive, assign and close its Facebook and Instagram leads.
Eder Estructuras
Proyecto propio, nacido de mi tesis
Structural analysis with the direct stiffness method, every step in sight: from springs to frames with seismic analysis under the Peruvian code.
Plenor
The website of an Arequipa urban developer, with 203 lots, a legal complaints book and an admin panel the company runs on its own.
Análisis matricial de armaduras con Python
A free book that guides civil engineering students through programming their own truss calculator with the stiffness method. As a PDF, on the web and as notebooks.
Products
Tools born solving real problems that you can try today. If they fit, I adapt them to your company.
eder-tipologia
Your client walks the apartment before it exists!
A sales page for each unit type: a 3D walkthrough with real furniture, the floor plan with measurements and an image of every room, in a link your agent sends on WhatsApp.
- A 3D walkthrough to scale, with real store furniture and your city's sun by the hour.
- The floor plan with every room's size: no more "how big is the living room?" on WhatsApp!
- "Will my bed fit?" answered before the visit, plus an image of every room for your social media.
It was born reviewing apartments for my family. The demo has the 5 unit types of Acces Residencial (Arequipa).
S/250S/100per unit type
Launch price until November 30, 2026
Why so cheap? I'm looking for the first developers to show real cases. 50% to start and 50% on delivery.
Demo in Spanish, made from the public brochure of Acces Residencial (Alferza); not an official page of the developer.
eder-cotizador
Quote in the showroom. Close at the meeting.
The quoting tool for a real estate showroom: the agent puts it on the TV, builds the quote in front of the client and hands over a branded PDF, ready to sign.
- The building floor by floor, with what's still available today.
- Discounts by meeting and a cap that requires management's approval.
- Payment plan, bank and colors per project, plus a management dashboard.
Born from the quoting tool I built for Magistral Constructora's showroom, which replaced their spreadsheet.

No lead is lost without an explanation.
The CRM for developers that sell lots: Facebook and Instagram leads come in on their own, get assigned automatically and are matched with your inventory.
- Each salesperson gets their lead instantly, with everything needed to call.
- Pipeline, reminders and lot inventory in one place.
- Which campaign sells and which one only spends, with the cost per lead.
It's the product version of the CRM I designed and run for Magistral Constructora. See the case study
A civil engineer who sat in the sales room.
I'm Eder: civil engineer and programmer. I worked inside a construction company and saw the villains up close: lost leads, quotes in spreadsheets, sales that live in someone's memory. Now I defeat them with software, and your company's could be next!
Here's how we defeat your villain!
01
Tell me about the villain
On WhatsApp or a call: what's done by hand, what gets lost, what hurts.
02
See it working
A demo with your data, so you decide with the screen in front of you, not a slide deck.
03
We build it together
Short deliveries: you see progress often and ask for changes in time.
04
And I stay!
I ship it, maintain it and improve it with whatever your team asks for. The villain never comes back.
Lab
Experiments I build to learn how the tools I use are made. They're not products: they're practice, with the code in plain sight.
Cronogramas
BonsaiInspired by MS Project / Primavera
A Gantt chart with critical path, calendars, resources and baseline. Dates aren't typed in: they're calculated. The scheduling engine is hand-written, without paid libraries.
10,000 tasks rescheduled in ~8 ms
Planos
BonsaiInspired by AutoCAD (2D)
2D CAD with a command line, object snaps, Ortho and window selection on an infinite canvas. Every command is a generator function, and OSNAP runs on a spatial index.
LINE, TRIM, OFFSET… and exports to DXF
Hojas
BonsaiInspired by Excel / Google Sheets
A spreadsheet with Spanish formulas and its own engine. Each cell is an atom of state, and the dependency graph between formulas builds itself.
1,000 rows × 52 columns, virtualized
