Short Description:

I help to build and launch Telegram mini apps, websites, and MVPs. I lead teams, design scalable systems, and handle full-stack and cloud infrastructure development.

Full Description:

Freelance backend and cloud infrastructure engineer with strong expertise in system design, scalable architecture, and software engineering for high-load environments. I work across the stack and specialize in building fault-tolerant, microservice-based systems and leading technical teams from MVP to production.

Key experience:

- Led technical development of a web application and Telegram mini app with 100K+ users
Tech stack: AWS (RDS, ECS, ElastiCache, ELB), React.js, Node.js
- Designed and implemented multi-regional infrastructure on GCP using VPCs, load balancers, and managed instance groups
- Built microservice-based systems with focus on performance, availability, and maintainability
- Set up CI/CD pipelines with blue-green deployment strategies for multi-regional GCP environments
- Developed a trading application on the TON blockchain for 30K users using DEX Stonfi
Tech stack: Docker Compose, React.js, Node.js, Cloud Run

Key achievements:
- Prototyped and deployed a fault-tolerant multi-regional architecture on Cloud Run for 400K users
- Reduced database query times from 2–4 seconds to 60–100 milliseconds
- Optimized core service response time from 4 seconds to 1–1.2 seconds
- Implemented versioning, multistaging frameworks, and clean CI/CD processes across multiple teams
- Introduced best practices for stress testing, observability, and incident resilience
- Led two cross-functional web development teams
- Built and scaled three additional teams (two outsourced, one in-house)

I focus on building robust, production-ready systems with clean architecture, automation, and reliable team delivery.
