IT consulting for SMEs

Whatever the technology,
I get it into production.

COalesCE is me, Alessandro Colace: when something goes wrong, you call me, not whoever supplied your ERP, your website or your email.

Custom software, data, legacy systems, security, AI.

The same person, every time.

  • DATA FOUNDATIONS

    If the numbers don't line up, I start from the data you already have; if the server is at end of life, from where it lives. Which of the two you're dealing with, I'll tell you on the first call.

    • DATA ENGINEERING
    • CLOUD DATA PLATFORM
    • DASHBOARDS AND REPORTING

  • SOFTWARE RESCUE

    When nobody dares touch a system anymore, I put it back in order or migrate it piece by piece, with any downtime agreed up front.

    • LEGACY SYSTEM MIGRATION

  • AI INTEGRATIONS

    From the first use case to a system that runs every day, not a demo that impresses once.

    • AI CONSULTING FOR SMES
    • FROM PILOT TO PRODUCTION
    • AI AGENTS & AUTOMATION

  • SECURITY AND COMPLIANCE

    What you actually risk, what your client is asking for and where to start, without selling fear.

    • CYBERSECURITY FOR SMES

  • CUSTOM TOOLS AND GOVERNANCE

    The tools you are missing and the calls you keep postponing: the costliest one is the decision nobody makes.

    • WEB & MOBILE APP DEVELOPMENT
    • FRACTIONAL CTO / CDO / CIO

  • TRAINING

    When you don't want to buy the work but to learn how to do it: three programs for your own people, on your own data and processes.

    • AGENTIC AI ADOPTION
    • DevOps & CLOUD ENGINEERING
    • DATA STORYTELLING

Waiting is not free.

The free chatbot of two years ago answered questions. Today's models read your company's documents and carry out a whole procedure: it's a different job.

From the first call to production, with no hand-offs.

I work inside the company as a Forward Deployed Engineer. The roadmap and the prototype move together: what the prototype turns up corrects the roadmap while the roadmap is still being written. And what I learn about your processes carries from one project to the next, because I'm the team.

  1. First call

    Tell me the problem in front of you. Free and no strings: at the end I'll tell you whether I can help or not.

  2. Assessment

    I look at your processes, your systems and where time gets lost, and I hand you a document with the problems ranked by impact, before a single line of code gets written.

    • Roadmap

      I set priorities, expected ROI and architecture together with you. A clear route, not a wish list.

    • Prototyping

      I build a working prototype and put it in front of the people who'll use it. In weeks, not months.

  4. Production and adoption

    I take the solution live and work alongside the people who use it every day, fixing what real usage turns up. Working isn't enough: if they don't use it, I stay on it until they do. Documentation and access stay with you.

The stack I work with.

A bottleneck to clear, or something a competitor already shipped: I'll show you how to build it.

Thirty minutes is enough for a technical read on your problem and the first step to take. If you don't need me I'll say so, and point you at the shortest route.
