Sound familiar?
- Hiring a senior HubSpot developer full-time is taking months.
- Your HubSpot codebase has grown messy and every change breaks something else.
- Offshore hand-offs and time-zone gaps turn one-day fixes into week-long threads.
- You need someone senior enough to make decisions, not just close tickets.

Common questions
Will this turn into a sales pitch?
No. The call is about your project: what needs building, what's stuck, and whether we have the right engineers. If we're not a fit, we'll say so.
What do I get for free?
A project plan, roadmap, cost estimate and ROI estimate within 48 hours of your project call. Your first 5 development hours are free, too. We agree the scope and any paid work with you before proceeding.
Do I need a spec or brief?
No. Tell us the problem in plain words and we'll help shape the scope with you.
Are the engineers really in the U.S.?
Yes. Every engineer lives and works in the United States. No offshore hand-offs, and that's in the contract.

Hire US-based HubSpot developers from NextGen Coding Company for HubL themes, Content Hub websites, CRM integrations, and custom workflow code. The right scope depends on your HubSpot subscription, content model, and connected systems. Start with the specific problem: modules editors cannot safely reuse, forms that lose attribution, duplicate CRM records, or integrations that fail when API limits are reached.
For website work, map templates, custom modules, HubDB tables, and local development with the HubSpot CLI. For CRM work, review object associations, authentication, webhooks, and synchronization rules before changing production data. Our engineers are senior, and many have more than ten years of experience. They live and work in the US, follow your working hours, and participate in your standups.
Frequently asked questions
- When do I need a HubSpot developer instead of a marketer?
- A developer is useful when the work extends beyond configuring pages, lists, and standard workflows. Examples include building HubL modules, connecting an external application through CRM APIs, or troubleshooting JavaScript that affects forms. Your marketer should still define lifecycle stages, attribution needs, and editing requirements so technical changes support the intended customer journey.
- Can custom HubSpot modules stay editable for marketing teams?
- Yes. HubL modules can expose structured fields for text, images, links, and repeatable content while keeping layout rules in code. Plan field groups, defaults, responsive behavior, and accessibility before implementation. A good review includes the page editor experience, not just the published page, so routine content changes do not require template edits.
- Should a HubSpot integration use a private app or OAuth?
- A private app can fit an integration built for one HubSpot account, while OAuth is generally appropriate for an application installed across multiple accounts. Review required scopes, token storage, account ownership, and distribution requirements first. The integration also needs rate-limit handling, retries, and monitoring; choosing authentication alone does not establish reliable synchronization.
- What causes duplicate records in HubSpot CRM integrations?
- Duplicates often come from inconsistent identifiers, overlapping import processes, or retries that create a new record instead of updating an existing one. Review external IDs, email-based matching where appropriate, association logic, and synchronization direction. Before a cleanup, define conflict rules and test a small dataset so legitimate contacts or companies are not incorrectly merged.
- How do I get started with a US-based HubSpot developer?
- Book a 15-minute call and bring your HubSpot subscription details, connected applications, and examples of the broken workflow or desired page behavior. Most teams interview matched engineers within a week of that first conversation. We sign an NDA and full IP assignment before touching code, and there is no offshore subcontracting.
- Are your developers really based in the US?
- Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.
- How fast can someone start?
- Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
