// beamstack · production software, engineered from the problem up

The right tool for your problem
might not exist yet.

That's not a reason to settle for the closest match.

Most software companies start with a product and hunt for problems it can solve. Beamstack flips that — it starts with the problem (the bottleneck, the workflow no SaaS tool quite fits, the process living in someone's head and three spreadsheets) and designs the software around it.

Beamstack is one person: A. Daoudi, a civil engineer who also architects and ships production software. The domain and the architecture meet in one mind — so there's no translation loss, and no kickoff call to learn what a site actually needs.

// 01 — the flip

I don't start with a product.
I start with the problem.

product hunt for a problem it can solve
problem design the software around it

Sometimes that means assembling proven architecture patterns. Sometimes it means building something genuinely new. Either way, what I ship is maintainable, scalable, and built to last.

// 02 — the edge

I understand the problem
from the inside.

I don't learn your domain from a kickoff call. I'm a civil engineer (EHTP) who also architects and ships production software — two rare disciplines in one mind. So when I build a tool for a site, a structure, or a workflow, I already know where the real constraints live. The person who knows the domain and the person who writes the code are the same person — zero translation loss.

You won't get a sales team or juniors learning on your budget. You get the engineer who built it — and who has stood on the site.

Abdellah Daoudi, founder of Beamstack
AD · REF.001

Abdellah Daoudi.

A licensed civil engineer and EHTP graduate who fell in love with code. Where others saw a gap between the physical and the digital, I saw a bridge waiting to be built.

Self-taught from the ground up, I architect software the way I design structures — with load paths, redundancy and precision. From structural analysis tools to production multi-tenant platforms, I bring an engineer's discipline to every line of code, and a developer's agility to every project on site. Moroccan-born, building for the world.

Chantier Manager
paid · SaaS

The first ERP built around the site, not around accounting.

The chef records one validated quantity from the field — and it feeds both your client billing and your real cost, so you see margin per lot, in real time, from signed contract down to Lot / sous-Lot. 100% web, multi-tenant SaaS.

30 m² of 100 done, but 45% of the lot budget already gone → you're about to overrun. No horizontal ERP gives you that signal.

six roles, one source of truth

Chef chantier
Files accurate daily reports and logs progress from the site.
Conducteur
Sets the baseline planning, logs progress from their phone, validates the chef's quantities, and generates the imputable décompte plus an on-demand non-imputable situation des travaux.
Pointeur
Defines crews and records the presence of human resources.
Magazinier
Tracks what moves in and out of site stock and global stock.
Comptable
Keeps track of payments and invoices.
Patron
Sees and edits everything, creates and revokes roles on demand, and watches what each role is doing.

Planitor
in development

Generative 4D construction planning — the schedule is produced from the model, not draped over it.

Backed by a design-science research paper formalizing the element-to-activity granularity gap. An academic paper from a vendor is almost unheard-of — it signals rigor, not vibe-coding.

Mainstream 4D BIM is presentational: a schedule authored in Primavera or MS Project, then linked to model geometry object by object, by hand. Planitor inverts that — the schedule is generated from the model.

  • Construction-variant abstraction — one reusable object anchors to IFC geometry, derives its quantities, and expands an element into its ordered activities (rebar → formwork → pour → cure → strip)
  • IFC ingestion (IfcOpenShell)
  • Deterministic CPM + EVM engines — critical path and earned-value cost
  • Degrades gracefully to a no-BIM parametric mode for SMEs who'll never produce a clean IFC model
  • 4D export — JSON / Excel / IFC4
  • Gives a 50-person contractor the planning intelligence an ENR-100 firm gets from a 10-person department
Road Designer

// 05 — de-risking one engineer

One engineer, none of the single-point risk.

The honest question a serious buyer asks: what happens if you're not around? Everything below is built so the answer is "nothing breaks." You own the work, and you can hand it to anyone.

You own the source & IP

Full source, infrastructure and intellectual property transfer to you. No per-seat licence, no lock-in, no hostage code.

Documented & handover-ready

Clean Architecture, typed contracts and CI-enforced boundaries mean any competent team can read, run and extend it — not just me.

Optional code escrow

For public-sector and enterprise procurement, the codebase can be placed in third-party escrow, released to you on agreed triggers.

Maintenance & SLA

Optional support and uptime SLA after delivery — observability, nightly backups and incident response already proven in production.

Direct access, always

You talk to the person who wrote the code. No ticket queue, no account manager relaying a half-understood requirement.

Proven in production

A live multi-tenant ERP running a real pilot is the track record — not a slide deck. The de-risking is already demonstrated.

// 06 — how I work

Problem → design → build.

01

Problem

The bottleneck, the workflow no tool fits, the process living in someone's head and three spreadsheets.

02

Design

Proven architecture patterns where they fit — something genuinely new where they don't.

03

Build

Maintainable, scalable software, built to last — and run.

// 07 — start here

Bring me your problem.

Tell me the bottleneck. I'll tell you what's buildable — and whether the right tool already exists or needs to.
