About

I build the parts of HubSpot that don't come out of the box.

I'm Roman Salom, a HubSpot developer and CRM consultant based near Buenos Aires. I help companies solve the problems standard HubSpot features can't: custom integrations, automation and CRM structures that connect HubSpot to the rest of the business and remove manual work.

From full-stack developer to HubSpot specialist

I trained as a full-stack developer first: two 800-hour bootcamps at Coderhouse (2022) and Henry (2023) in React, Node.js and databases, plus a cybersecurity course. Then, in mid-2024, I joined Happy Agencies as a HubSpot web developer working on international client projects.

That's where I found what I actually love: the place where code meets business process. CRMs, integrations, data that moves between systems on its own. I built workflows on custom objects, custom cards powered by serverless functions for quote automation, and dynamic HubL templates, and decided to specialize in HubSpot.

Most HubSpot problems aren't code problems or settings problems. They're both.

Today I work as a HubSpot CRM consultant and n8n developer with Revenue Institute and We Simplify, a UK agency, both HubSpot Solutions Partners, designing CRM structures from scratch: pipelines, lead flow architecture and qualification workflows. Before that I built a complete CRM for Mappa.ai and a Shopify-to-HubSpot real-time sync for an e-commerce brand.

Today I also work directly with end clients (founders and sales, ops and RevOps leaders) who want reliable systems rather than one-off zaps. I'm completing an Associate Degree in Systems Analysis at ORT, and I work from Tigre, just outside Buenos Aires, in hours that overlap with US teams.

I understand the whole HubSpot ecosystem, not just the code.

A good fix starts with how your business works. Then I pick the right layer: a setting, a workflow, custom code, an external tool or AI.

  • CRM architecture

    Pipelines, deal stages, lifecycle, properties, custom objects and associations.

  • Sales, Marketing & Service Hubs

    Workflows, sequences, lead flow, qualification and reporting.

  • Custom development

    Custom-coded workflow actions, UI extensions and custom cards, serverless functions, HubSpot APIs and webhooks, CMS and HubL.

  • Automation & AI

    n8n, Make and OpenAI for multi-tool flows, document processing and enrichment.

  • Data & adoption

    Data cleanup, migration, onboarding and training so your team actually uses it.

How I work

  • Process before tools

    I map how your team actually works before I build anything.

  • Reliable over clever

    Validation, retries and clear logic. Automation should hold up, not just demo well.

  • Plain English

    You'll understand what was built and why, with no black boxes.

  • Direct line

    You talk to the person doing the work, during your business hours.

  • Honest scoping

    If a native feature or an existing app solves it, I'll tell you, even if it means less work for me.

  • You own everything

    It's built in your accounts, documented, and handed over.
