Featured case: Low-latency trading backend & real-time Telegram WebApp

Technical demonstration of a custom system focused on stability, low latency and predictable transaction lifecycle control. The UI is a Telegram WebApp with real-time charts and trading controls.

Demo video

Video shows: multi-chart layout, buy/sell flow, scale updates, trailing stop & stop controls, quick toggle actions, a settings change, and live runtime logs.

What was built

Node.js backend with asynchronous state management and failure handling
Optimized transaction preparation to avoid unnecessary on-chain calls at execution time
Custom transaction lifecycle control (TTL / block reference logic)
Event-driven confirmation tracking via streaming data (gRPC) to reduce reaction latency
Real-time WebSocket transport to UI (Telegram WebApp)
1-second candle generation and charting (TradingView)

Source code is not published (internal logic / NDA constraints). Small non-sensitive snippets can be shown on request.

Screenshots

Other experience

Joomla-based portal with deep PHP customization and data aggregation across multiple modules
Linux server infrastructure: routing/firewall, VPN/proxy setups, and network troubleshooting
Blockchain work: integrations on Solana/Ethereum; Ethereum smart contracts (custom logic and upgrades)
LLM systems integration: local search pipelines, context preparation, and WebUI extensions

Engineering background

Started programming long before modern frameworks became mainstream. Worked with a wide range of languages and platforms over the years.

Current focus: Node.js / JavaScript backend systems, LLM integration & tooling, Telegram-based solutions, PHP for legacy and custom platforms.
