I help 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.
