Telegram can make a frequent task easy to reach: record an expense, receive a status update, complete a short request, or open a richer interface from a conversation. I develop bots and Mini Apps around the task itself, choosing which actions belong in chat and which need a web interface.
SpendiFly is my own product and a concrete example of this combination: an everyday expense tracker available through SpendiFlyBot and a Telegram mini app. Its portfolio page documents the product scope and provides a direct bot link. I use that product context to discuss flows and tradeoffs without promising a result that depends on your audience or business model.
When this service fits
For recurring personal or team workflows, product companion bots, and Mini Apps that need structured forms or richer views. Begin with example messages, the core action, user roles, and the systems that must exchange data.
Bot commands and conversation design
A conversational flow needs clear entry points, useful confirmation, and an escape path when input is incomplete. I define commands, buttons, and the state behind multi-step actions. Repeated messages, edited input, and a user returning after a long pause should have predictable behavior instead of leaving the conversation stuck.
Mini App interfaces
A Mini App is useful for lists, charts, forms, and settings that are awkward to express through messages. I build responsive web interfaces with attention to the Telegram container, theme, navigation, and small screens. The bot and Mini App should share the same underlying account and business rules rather than maintaining competing copies of state.
Identity and data boundaries
Backend access needs server-side identity validation and action-specific authorization. I keep bot credentials out of browser code and define how user records, shared spaces, and exports are owned. For sensitive information, we agree what is stored, what is included in messages, and how deletion and retention should work.
Webhooks, integrations, and reliable delivery
Bot delivery needs safe handling of duplicate updates, external API failures, and work that takes longer than a request. I define idempotent operations, bounded retries, and visibility into failed jobs when needed. Notification behavior should include user preferences and rate limits, with a deployment plan for secrets and webhook configuration.
What the handover includes
- An agreed command map and complete bot or Mini App workflow.
- Backend integration with documented identity and access boundaries.
- Setup, secret configuration, deployment instructions, and failure-handling notes.
Development process
Choose the interaction surface
Map the recurring task and decide which steps work best as messages, buttons, or a Mini App screen.
Connect identity and data
Define account ownership, validation, shared access, and the backend rules behind each action.
Test interruptions and duplicates
Exercise repeated updates, missing input, failed integrations, and a user returning to an incomplete task.
Release with a support path
Verify webhook and secret configuration, document operations, and agree how user feedback reaches the product owner.

Frequently asked questions
Do I need a bot or a Mini App?
A bot works well for short inputs, notifications, and direct actions. A Mini App suits richer browsing, forms, and visual summaries. The same product can combine both, with shared data and a clear transition between chat and interface.
Can the bot connect to my current product?
Yes, when suitable APIs and account-linking rules are available. We review authentication, data access, event delivery, and the behavior expected when your existing service is unavailable.
What do you need to estimate the work?
Send example conversations, the intended audience, required integrations, and whether the product needs a Mini App. Include account roles and any sensitive data involved so the first scope covers the important boundaries.
