Mikhail P.

Senior Full-Stack Engineer (React / Node / AWS)

Toptal-vetted Solutions Architect and a senior full-stack developer. I design clear system boundaries, enforce strong contracts, and build scalable, maintainable foundations for SaaS platforms. I deliver: • AWS CDK-driven infrastructure, CI/CD with CodePipeline, multi-account governance (Organizations, Security Hub, Config), and observability (Grafana, Sentry, CloudWatch). • Cloud-native backend on ECS and Lambda using DynamoDB, RDS, EventBridge, and SNS/SQS. Temporal workflows and REST, GraphQL, gRPC services in Node.js, Python, and Go. • React and React Native applications using RxJS and TypeScript codegen for integration with backend services. • Domain-driven design, dependency injection, functional patterns, and comprehensive testing strategies (unit, integration, API, E2E). AWS Certified Solutions Architect - Professional with hands-on experience in security hardening, performance and cost optimizations. I design resilient, distributed systems and implement CI/CD pipelines that enable confident, repeatable releases. I use AI as a force multiplier deliberately applied: • Identifying delegatable tasks with clear acceptance criteria, low risk, and high implementation overhead. • Enforcing type constraints and automated checks, providing agents with tooling and guardrails for continuous operation. • Reviewing all code that reaches production, while validating as much as possible through automation. I ship as early as possible while maintaining a high standard of quality. If you value consistent, reliable progress - I can help.
