Esterdigi · bespoke software engineering
We design and build from scratch, with architecture that keeps up as the business grows and code that is still readable years later. The same engineering that has kept systems that cannot stop running for 29 years.
Six practices, one standard: a clear scope, bespoke design, reviewed code and the system measured after it goes live.
Corporate websites, showcases and sales pages designed around your brand, with fast loading, technical SEO, multiple languages and every conversion measured.
Complete digital products: customer area, dashboards, subscriptions, permissions and reports, on an architecture that keeps up as users and features grow.
Apps published on the stores and tied to the same account as the web version, with notifications, offline use where it makes sense and continuous updates.
Mission-critical systems for financial, industrial and healthcare operations, and the migration of legacy systems to modern architectures without stopping the business.
Systems that talk to each other: payment gateways, instant payments, ERPs, sales platforms, WhatsApp and AI agents that answer and act on your company's data.
Monitoring, fixes and ongoing evolution of production systems, with second- and third-level technical support and an improvement plan every cycle.
You always know which stage the project is in, what comes next and what you can already test. No black box.
A conversation to understand the business, the problem and the constraints. We define the goal, what is in and what stays out.
Proposal with scope and timelineWe design the solution before writing code: screens, flows, data and integrations, validated with you.
Prototype and technical planShort, frequent deliveries, with a test version you can open every cycle, without waiting for the end of the project.
A working version every cycleLaunch, measurement and follow-up. Then the system keeps evolving with us or is handed over to your team.
