What We Do

Services

Python backend specialists. Clean code that ships on time and holds up in production.

01
Telegram Bots
Bots with real features. Subscriptions, payments, alerts and custom logic. We have shipped bots with hundreds of active users.
02
API Development
REST APIs with FastAPI and PostgreSQL. Fast, documented and ready to scale from day one.
03
Automation
Stop doing things manually. We build automations that run while you sleep. From simple scripts to full multi-step pipelines.
04
Web Scrapers
Reliable data extraction at scale. Anti-detection, proxy support, structured output and scheduled runs with monitoring.
05
Integrations
Connect your tools. Payment gateways, third-party APIs, webhooks and CRMs. If it has an API, we can connect it.
06
Data Processing
Raw data in, clean structured output. Pipelines that transform, aggregate, store and deliver data where it needs to go.
07
Dashboards
Visual interfaces on top of your data. We connect scrapers, databases and pipelines to clean dashboards so you can actually see what is happening in your system.
08
AI Integrations
We connect OpenAI and Claude into your existing systems. Intelligent agents, document processing, smart bots and any workflow that benefits from AI.
09
Database Design
Schema design, query optimization and database management. We build structures that are fast now and easy to extend later.

How We Work

No surprises. You know what is happening at every step.

01
Discovery
You tell us what you need. We ask the right questions to understand the scope, timeline and any technical constraints before touching any code.
02
Proposal
We send a clear breakdown of what gets built, how long it takes and what it costs. No vague estimates. No surprises after you say yes.
03
Development
We build and keep you updated throughout. You can see progress, ask questions and give feedback at any point. We keep things simple and well documented.
04
Delivery
Clean code, documented and deployed. We make sure everything is running correctly before we close the project. Source code is always included.
