Hello World

This page lists only projects led or delivered through Hello World. Other roles and confidential work are not shown here.

• Customer loyalty program

  Cefa / Celmar

  Costa Rica & Panama

  We designed and built a regional loyalty program so Cefa / Celmar could reward repeat customers and run promotions consistently across Costa Rica and Panama. The work covered the public-facing web experience, the rules and workflows behind earning and redeeming benefits, and the pieces needed to fit the program into how each market already operates. The goal was a single coherent experience for users while still respecting local processes, so the team can grow engagement without juggling disconnected tools.

• Banking integrations & communications

  Banking sector

  Costa Rica

  For this banking engagement we connected internal systems to SINPE—Costa Rica’s national electronic payments network—so the right payment and transfer flows could run in a controlled, auditable way. Alongside those rails, we implemented communication touchpoints so the institution can notify and guide customers at the right moments, in step with transactions rather than as an afterthought. The emphasis was reliability, clarity for end users, and a setup staff can operate with confidence day to day.

• CRM platform

  Newo

  Regional

  Newo needed more than a generic CRM: a workspace that matches how their team actually prospects, follows up, and hands work between roles. We delivered a custom web-based CRM with pipelines, contact history, and the day-to-day actions their commercial and support staff rely on—without forcing them into someone else’s idea of a funnel. The result is one place to see the full relationship with each account, reduce duplicate effort, and keep momentum on deals and service requests.

• Odontogram

  America Dental

  Regional

  America Dental’s teams needed a proper digital odontogram: an interactive tooth chart in the browser where clinicians can record conditions, planned work, and progress over time. The solution makes it easier to keep visits consistent between providers, show patients what is happening in their mouth, and maintain a clear record for treatment planning. Building it as a web application keeps it accessible where they already work, with a focus on clarity and speed during appointments.

• Point of sale (POS)

  Farmacia MSJ

  Costa Rica

  Farmacia MSJ required a point-of-sale system tuned to a pharmacy: fast checkout at the counter, sensible handling of products and pricing, and workflows that match how staff serve customers under pressure. We built a custom POS as a web application focused on reliability and ease of use—so ringing up sales, adjusting lines when needed, and keeping the day moving stays straightforward for the team on the floor.

• Landing page & property presentations

  RedRod

  Costa Rica

  redrodestate.com

  For RedRod—luxury real estate in Costa Rica—we produced a marketing experience aligned with their positioning: exclusive properties and high-touch service. That includes a conversion-focused landing flow and property presentation pages that showcase listings with photography, key facts, and narrative in a layout that reads well on phones and desktops. Together it gives RedRod a strong first impression and a repeatable way to present homes to buyers and renters.

• Brand landing page

  Terre de Vie

  Regional

  terredevie.co

  Terre de Vie is a bioland-oriented hair-care brand built around natural, sustainable cosmetics—think shampoos, treatments, and collections that put ingredients and environmental commitment front and center. We delivered a marketing landing experience that presents their product lines (e.g. hydrating and nourishing ranges), ingredients story, and brand promise in a layout suited to discovery on mobile and desktop. The site supports their positioning as a modern, conscious beauty brand and gives shoppers a clear path to explore collections and learn what goes into each formula.
