What devFlorence is

A senior-led, AI-assisted software studio.

Not a large agency. Not a generic outsourcing shop. devFlorence is a senior-led software studio founded by Alessandro De Stasio, combining 30+ years of software engineering experience, 28 years on the Java technology stack, practical architecture, and modern AI-assisted execution without replacing engineering judgment.

Custom-fit software

Software should support the processes that create your advantage.

Generic SaaS products are built for averages. devFlorence builds dedicated applications that reflect your process logic, business rules, data flows, and operational constraints.

The devFlorence approach

Purpose-built systems instead of SaaS-shaped compromises.

We implement only what creates value, focus the product around the process requirements that matter, and shorten the path from idea to market without adding operational bloat.

Your processes first Only useful features Domain-specific model Faster path to market

Services

Software development where business fit and experience matter most.

For businesses that need software shaped by their process requirements, devFlorence builds dedicated systems with senior architecture, modern Java engineering, and production-focused delivery.

Architecture & technical leadership

System design, technical direction, trade-off analysis, and architecture that stays understandable after the first release.

Legacy Java migration

Pragmatic assessment and incremental migration of legacy Java applications toward current runtimes, maintainable architectures, and cloud-ready deployment.

Dedicated business applications

Focused tools, internal platforms, APIs, automation, and process systems designed around your real operating model.

Cloud, serverless & integration

AWS-native systems, event-driven design, real-time messaging, and integration layers that avoid unnecessary operational weight.

Principles

Simple systems. Clear ownership. Production discipline.

devFlorence keeps the engineering surface intentionally focused: clear process models, explicit boundaries, modern Java foundations, and AI assistance under senior technical control.

KISS, YAGNI, DRYPrefer simple designs that solve today’s process requirements. Avoid speculative features, duplicated logic, and abstractions without evidence.

Process model firstEncode the business process clearly: rules, states, decisions, data ownership, and the language your team already uses.

Production‑ready architectureChoose boring where possible and modern where useful: Java, serverless, reactive patterns, observability, and maintainable boundaries.

AI-assisted, not vibe-codedAI helps explore, implement, and validate faster — but architecture, security, tests, and production accountability remain engineering-owned.

A complete messaging product, built with engineering depth.

Neurons is an integrated messaging platform deployed in the customer's AWS account. It combines Matrix-compatible E2EE for messages and attachments, elastic serverless scaling, real-time push delivery, Matrix server-server federation, and an extensible foundation for domain products.

About

Direct senior ownership from architecture to production.

devFlorence is a senior-led software studio founded by Alessandro De Stasio, bringing 30+ years of software engineering experience and 28 years on the Java technology stack.

Trusted AI agents extend research, implementation, testing, documentation, and delivery speed — but architecture, trade-offs, code quality, and production decisions remain senior engineering responsibilities.

Compared with a traditional agency, the model is lighter and more direct: fewer layers, faster decisions, and continuous technical ownership grounded in the process, the architecture, and the long-term cost of the software.
