Turnkey web app and Telegram bot development

We build web apps that work just as well on a phone as on a desktop, and Telegram bots that send notifications and hold a conversation with the user, turnkey. You see a working version early in the project. Example: the rynda.io app and its bot, which reports vessel events and helps post a request right inside Telegram.

What we build

Apps people actually use

  • Web apps for phone and desktop

    One responsive version: touch-sized buttons, forms that do not zoom on iPhone, checked at phone width.

  • Customer portals

    Lists, cards, filters, team access and plans: the usual toolkit of a customer-facing service.

  • Telegram bots

    Event notifications, conversations, confirmations and moderation right in the messenger.

  • AI-powered bots

    The bot understands free text and files, asks follow-up questions and fills in the request for the user.

  • Notifications

    Event rules, delivery to Telegram and email, settings for each user.

  • Analytics from day one

    Product events in PostHog show where users reach their goal and where they drop off.

What’s inside

  • Vacancies with public pages. Every vacancy from a shipowner or an agency gets its own page.
  • Seafarer resume. A step-by-step wizard: rank, experience, documents and certificates.
  • Applications and hiring stages. Applications with statuses, from new to hired.
  • Chat with candidates. Shipowners and seafarers message each other on the platform.
  • Subscriptions and payments. Employer plans, invoices and payments.
  • Linked to rynda.io. Crewing vacancies on the vessel card and in the account.

Quality

Fast, and checked

The code this page talks about runs on rynda.io every day. The team writes it, ships it and fixes it.

  • Screenshots of every changed screen on phone and desktop, in both languages.
  • Accessibility: every button can be tapped and reached by keyboard, and focus is visible.
  • Cards in a row share one height, and prices and labels are never cut off. We measure it in the browser.
  • Important messages never disappear on their own after a few seconds.
FAQ

App development FAQ

What kind of apps do you build?

Web apps and customer portals that run in the browser on phone and desktop, and Telegram bots with notifications, conversations and AI.

Why a Telegram bot if there is an app?

A bot delivers the event where people already read messages: a rynda.io user learns that a vessel arrived in port from Telegram, without opening the site.

Will the app work well on a phone?

Yes. We check every screen at phone and desktop width; buttons are at least 44 pixels and input fields do not zoom the page on iPhone.

How much does it cost and how soon is the first version?

It depends on the number of screens and flows. We show a working version early in the project and give a price after scoping. Send a request or email info@rynda.io.
