Software built like it
has to last.

Softwarelogicforge designs and builds web applications with real engineering discipline underneath — architecture first, interface second, so the thing you ship still runs cleanly a year later.

What we build

Six disciplines,
one build pipeline.

Every project moves through the same sequence — no step skipped, no handoff dropped.

01 / 06

Systems Architecture

We map the technical foundation before writing a line of production code — data models, service boundaries, the decisions that are expensive to reverse later.

02 / 06

Frontend Engineering

Interfaces built with real component architecture — not a pile of divs — so new features don't mean rebuilding old ones.

Learn more →
03 / 06

Performance Engineering

Load times, Core Web Vitals, and technical SEO handled at build time — measured on every deploy, not audited once a year.

Learn more →
04 / 06

CMS & Content Systems

Editable content structures your team can actually update without filing a ticket — headless CMS setups built around your real content model.

Learn more →
05 / 06

DevOps & Deployment

Continuous integration, staging environments, and monitoring set up once, so shipping updates is a routine push — not an event.

06 / 06

Analytics & Data Engineering

Event tracking and dashboards wired up correctly from day one, so growth decisions are based on real data, not a gut feeling.

About softwarelogicforge

Built the way we build software.

A short version control history of the studio.

2017 · FOUNDED

Two engineers, one workshop in Móstoles

Softwarelogicforge started as a two-person team taking on the projects local agencies didn't want — the ones that needed actual engineering, not just a template.

2019 · V2.0

First enterprise client, first real deadline pressure

A logistics platform rebuild taught us the lesson that still runs the studio: architecture decisions made in week one determine whether week fifty is calm or chaos.

2022 · V3.0

In-house DevOps practice

We stopped handing off finished sites and started owning deployment pipelines too — because a site nobody can safely update stops being useful fast.

2026 · TODAY

A full-stack studio working across Spain

Today we design, build, and maintain web applications for banks, logistics companies, and retailers — most of whom came to us after inheriting a codebase nobody wanted to touch.

past the demo.

★★★★★

"Two years in production and we've never had to call them about a fire. That's the whole review, honestly."

MI
Marta Iglesias ReyCTO, Banco Atlántico Digital
★★★★★

"They inherited our old codebase, didn't complain once, and left it better documented than we'd ever had it."

OP
Óscar Peña CasalsIT Director, Grupo Logística Ibérica
★★★★★

"The performance audit alone found issues our last three agencies missed. Load time dropped by half."

LF
Laura Ferreiro DuqueHead of Digital, Telecom Levante
★★★★★

"Straightforward pricing, no scope creep, and they actually said no to a feature that would've hurt us long-term."
