Based in Dublin. Available for remote work across Ireland, the UK, and Europe.
TL;DR
- Senior software engineer with 10+ years across backend, cloud, databases, and product engineering
- Best fit: SaaS teams, startups, technical founders, and engineering teams with delivery or architecture bottlenecks
- Services: backend development, system design, refactoring, technical audits, infrastructure, performance work
- Technologies: Java/Kotlin, Ruby/Rails, Node.js, Python, PostgreSQL, AWS, Kubernetes, Kafka
- Engagements: project-based, hourly, or light retainer
Services
What I help with
Architecture and technical direction
Technical decisions before complexity becomes expensive: service boundaries, database design, scaling strategy, infrastructure choices, and pragmatic trade-offs.
Refactoring and modernization
Legacy or fast-grown systems where the product works, but the codebase, data model, or deployment process is slowing the team down.
Technical audits
Focused review of a system, architecture, database, infrastructure, or delivery process, followed by practical recommendations and a walkthrough.
Engagements
Typical engagements
Startup backend build
For product ideas, prototypes, or frontends that need a reliable backend foundation. Includes APIs, authentication, database design, deployment, monitoring, and production readiness.
System review
For teams unsure whether the current architecture will scale, whether the codebase is maintainable, or where the technical risks are. Includes findings, risk areas, and concrete recommendations.
Fractional backend engineer / architect
For teams that need senior technical input without hiring full-time. Useful for roadmap planning, implementation support, technical decisions, and mentoring.
In scope
- Backend systems and APIs
- PostgreSQL and data modelling
- Cloud infrastructure and deployment

About
I'm Aldo Ambrosioni, a senior software engineer based in Dublin.
I've worked across product companies, SaaS platforms, enterprise systems, and R&D environments. My work has covered backend engineering, architecture, databases, infrastructure, integrations, refactoring, and production operations.
I'm most useful where teams need someone who can move between code, architecture, product constraints, and operational reality.
Working style
Direct, pragmatic, production-minded.
I work directly with you. No agency layer, no handoff to junior developers, no unnecessary process.
You can expect clear communication, pragmatic trade-offs, and a bias toward systems that are simple enough to understand and strong enough to run in production.
