01Services

What clients hire us for

The whole cycle in one place: concept, specs, design, code, servers and support. No subcontractors, and no information getting lost between handoffs.

  1. Telegram bots

    Service, payment and game bots. Queues, anti-spam, CRM integrations, crypto and fiat payments.

  2. Telegram Mini Apps

    Full-fledged apps inside Telegram: stores, games, dashboards. Native gestures, vibration feedback, TON payments.

  3. SaaS platforms

    Web services with subscriptions, billing, dashboards and admin panels. Architecture that holds up as you grow.

  4. AI solutions & integrations

    LLM chatbots, support assistants, content generation, routine automation. Quick to prototype, thorough on the way to production.

  5. Websites & web apps

    Landing pages, corporate sites, marketplaces, dashboards. Fast, tidy, and nothing that looks like a template.

  6. Payment integrations

    USDT and other crypto, card acquiring, subscriptions, invoicing. Every payment gets reconciled against the balance.

02Architecture

One team instead of five

A typical product, mapped out: we design, build and connect every part — from the bot to the servers. One party responsible for the whole stack.

Diagram: the set depends on the task — we build only the parts you need.

03Process

7 stages, in full view

Scope and timeline are fixed before we start. You always know what stage your project is at.

  1. Brief

    A call or a Telegram chat. We go through the task, your goals and the budget range.

  2. Concept & specs

    We prepare the technical specification: features, architecture, stack, milestones, timeline.

  3. Design

    Prototypes and UI: an interface that's a pleasure to use — and to show to investors.

  4. Development

    Iterations with interim demos — you see a working product, not status reports.

  5. Testing

    Functional and load testing, security audit, polishing the details.

  6. Launch

    We take the product live on our servers or your hosting. Domains, SSL certificates, monitoring — we set up everything.

  7. Support

    We keep evolving the product after release: new features, updates, on-call monitoring.

04Payment

Pay for each stage’s result

Each stage ends with a result you review and accept; payment follows only after that. The price is fixed after the brief and specs.

  2. 02Resultwe show what’s done
  3. 03Reviewyou check and accept
  4. 04Paymentonly after acceptance

Stages

The scope, deliverable and timeline of every stage are fixed in the specs before work starts.

Acceptance

At the end of each stage we show the result. You accept it, and only then is the stage paid.

Support

After launch we look after the product: updates, monitoring and improvements as agreed.

Payment — per milestone in USD / USDT: you pay for the result of each stage, not for promises. The price is fixed after the brief and specs.

07Why WebFi

You talk straight to the engineer

  • Turnkey — for real

    Idea, specs, design, code, servers, support. One party responsible for the whole stack instead of five contractors.

  • Direct line to the engineer

    No account managers in between: you work directly with the team building your product.

  • Modern stack & AI expertise

    A modern stack and hands-on LLM work. After launch we maintain and evolve the product so it stays current.

  • Post-release support

    We don't vanish after launch: we monitor, update and grow the product with you.
