ADCOM GROUP

CRM & MarTech Developer

CRM, MarTech and the platform that publishes 100+ landing pages

Overview

ADCOM Group is a marketing agency in Medellín. It runs admissions campaigns for universities and digital campaigns for consumer brands, national lottery brands among them, and every lead from those campaigns has to reach Zoho CRM with the campaign that brought it.

I joined the MarTech team in February 2025 as a CRM and web developer. In June 2025 I also took over the agency's servers and the integrations with its clients' systems, and later the platform that publishes its landing pages.

    I set up modules, workflows and Deluge functions on Zoho CRM, integrated WhatsApp, Meta Ads and Google Ads through their APIs, built internal apps on Zoho Creator and automated lead outreach with AI agents on Dapta.

    On top of the CRM came the integrations with the clients' academic and commercial systems, running the VPS (SSH, SSL, Nginx, Docker and deployments with GitHub Actions), internal services such as Prometheus, Nagios and n8n, and technical advice to the development, marketing and analytics teams.

What I did

  • Configure Zoho CRM modules, workflows and custom Deluge functions to automate sales and admissions operations.
  • Built 90+ admissions landing pages and microsites for higher-education campaigns, connected to Zoho Forms and Zoho CRM to capture and route leads.
  • Built the platform that publishes the landing pages. A reusable GitHub Actions workflow builds each one, checks its path, compresses the files and uploads them with rsync to the VPS, where one Nginx per client serves it without rebuilding images or restarting anything.
  • Maintain the 100+ landing page repositories with scripts that apply one change to all of them, a daily monitor that checks HTTP status, Google Tag Manager, compression, caching, pending deployments and certificates, and a weekly Lighthouse run on the main landing pages.
  • Integrate WhatsApp, Meta Ads, Google Ads, Typeform and Shopify with Zoho CRM through REST APIs and webhooks, plus serverless automations on the Zoho API.
  • Wrote the bulk operation tools on the Zoho API, with resumable batch loads, links, tags and deletions from CSV, and a client sync between one client's Oracle database and its CRM.
  • Developed results APIs and an HTML template generator with Spring Boot and Thymeleaf for national lottery brands.
  • Automated the emails of the lottery brands. A Python script with Jinja2 builds the nightly results email from the results API and Amazon SES sends it once every draw is in, while the welcome and birthday emails carry the name and segment of the person who receives them.
  • Built a FastAPI receiver that stores the delivery events of the results emails (Amazon SNS) in PostgreSQL, to measure every send.
  • Built a real estate agency's lead capture site. A GitHub Actions workflow publishes the inventory of its Wasi account every day before dawn, and requests for advice, contact and visits land in Supabase.
  • Automated lead contact with AI agents in Dapta and built internal applications in Zoho Creator.
  • Administer a VPS with Docker, Nginx, SSL, Prometheus, Nagios and n8n that hosts internal tools and automations.
  • Advise the development, marketing and analytics teams on API integrations, automation flows and data architecture.
