Hi, I'm

Yubor
Molina

Software Engineer & Full-Stack HubSpot Developer

5 years of experience.

Services

What I can
build for you.

🚀

HubSpot App Development

Have a SaaS product? I'll build a native HubSpot App that connects your platform directly to your clients' CRM — making your tool a seamless part of their HubSpot workflow.

⚙️

Custom Software

Stop working around your tools — make them work for you. I'll architect and build tailored software that encodes your exact business logic, eliminates manual steps, and scales with your operations.

🔗

CRM Integration

Every business has a unique stack. I'll connect your CRM to the tools you already rely on — syncing data, triggering automations, and eliminating the gaps where leads and revenue fall through.

💻

Website that Converts

A great website does more than look good — it drives pipeline. I'll build a fast, well-structured site optimized for SEO, performance, and the user journeys that turn visitors into customers.

A mix of apps, integrations and websites I've shipped.

Full-Stack Fintech Platform

Lukkra

Building the product end to end — a Next.js frontend, Node.js services for the application logic and API layer, and a PostgreSQL data model behind them. The focus is on automating the manual side of tracking money, so the platform handles the bookkeeping instead of the user.

HubSpot Marketplace App & Integration Layer

TitanX

Built the full application listed on the HubSpot Marketplace — both the in-app frontend and the backend powering it. The frontend surfaces TitanX data directly inside HubSpot through custom CRM cards and UI extensions, while a Cloudflare Workers backend handles OAuth, webhook events and two-way data sync, acting as the bridge that keeps HubSpot portals and the TitanX platform in step.

Corporate Website Build & Technical SEO

Webdox CLM

Built and maintained the public-facing site on HubSpot CMS for a Contract Lifecycle Management product, developing custom templates and modules in HubL with JavaScript for the interactive sections. Handled technical SEO across the site — metadata, page structure and performance — to support organic acquisition.

Website Development & SEO Management

Rankmi

Led development of the public website for an HR performance management platform, building custom HubL modules, automated workflows and third-party marketing integrations on HubSpot CMS. Also owned the SEO strategy — technical audits and on-page optimization — which improved organic visibility and lead quality.

Blog Development — Listing & Post Templates

Paula Inc.

Developed the company blog on HubSpot CMS, building both the listing page and the individual post template from scratch in HubL. Structured the templates around SEO best practices — semantic markup, a clean heading hierarchy and optimized metadata — so articles index and rank properly as the content library grows.
