Discovery
Understanding the task, the users, current processes and real constraints before writing code.
[Vladyslav Savchenko] Backend & AI Automation Systems Engineer
Backend Systems.
AI Automation.
Real Products.
I design and build Python-powered backend systems, AI integrations and automation platforms — connecting complex logic, data and user interfaces into reliable software products.
Based in Gdańsk, Poland · Remote Worldwide
01[Technical philosophy]
Build systems, not disconnected features.
Reliable software requires more than working code. Architecture, data integrity, observability, failure recovery and maintainability matter just as much as functionality.
- 04Interfaces
- 03APIs & integrations
- 02Logic & validation
- 01Data & state
Six disciplines, one system.
Grouped the way they meet in real products — not a wall of logos.
Services that coordinate work, talk to the outside world and keep going when it misbehaves.
- Python
- Async / await services
- Backend architecture
- REST API integrations
- Webhooks
- JSON processing
- Business logic
- Background workers
- Scheduled jobs
- Event processing
- Error handling
- State management
- External service integrations
Data models that stay correct as more subsystems read and write them.
- SQL
- SQLite
- Data modeling
- Database-driven logic
- User state persistence
- Trading event storage
- Data validation
- Data integrity
- Data pipelines
- Reporting datasets
- Event history
- Structured logging
Language models where they help, deterministic rules where correctness matters.
- OpenAI API integrations
- LLM-assisted processing
- Conversational AI
- Context-aware workflows
- AI memory
- Hybrid AI + rules
- AI classification & analysis
- Structured output validation
- Prompt-based task decomposition
- Model response validation
- AI workflow engineering
Interfaces that make complex backend state understandable.
- Telegram Bot API
- Telegram Mini Apps
- Web interfaces
- HTML, CSS, JavaScript
- Responsive design
- SVG visualisations
- Multilingual UI
- Subscription interfaces
- Admin panels
- Mobile WebView
- Onboarding flows
Market data, signals and risk controls — engineered, not promised.
- Binance Futures API ecosystem
- Crypto market data
- Signal generation
- Market condition analysis
- Risk validation
- Entry / SL / TP logic
- Position tracking
- Signal lifecycle
- Trading analytics
- Outcome reporting
- Leverage & exposure controls
- Automated monitoring
Getting software running, keeping it observable, proving it still works.
- Linux VPS
- SSH
- Deployment
- Background processes
- Server monitoring
- Logs & diagnostics
- Process lifecycle
- Regression testing
- Production acceptance
- Failure investigation
- Operational reports
- Playwright testing
03[Selected work]
One real platform.
Eight engineering stories.
Astra Raven is a production trading & AI automation ecosystem. Its subsystems are presented here as individual engineering case studies — alongside standalone tools built around it.
Not separate client projects. One system, many hard problems.

05[Development process]
From discovery to maintenance.
Architecture
Designing the main components, data structures and integrations — and how they fail.
Implementation
Building backend, interfaces and automation step by step, in reviewable increments.
Validation
Testing system behaviour, errors, states and critical scenarios, not just the happy path.
Deployment
Releasing to the right environment and checking how it actually behaves there.
Maintenance
Monitoring, diagnostics and continued development after launch.
AI-assisted development is used to move faster — never as a replacement for technical control. Every change is understood, reviewed and verified.
