I’m a Software Engineer with 10+ years in production development across Web, Fintech, Web3 and distributed systems. I build end-to-end solutions from architecture and implementation to performance, security and CI/CD.
My experience includes multi-chain dApps, non-custodial (and custodial) wallets, SocialFi products and high-load projects. I work across EVM, Solana and Cosmos ecosystems and contribute to system design and architectural decisions in fast-moving product teams.
I care deeply about secure engineering, supply-chain protection (LavaMoat, pnpm safety features), cryptographic standards and compliance-aware development for Web3/fintech environments. I used also StepSecurity and Socket.dev Actions and API, pnpm security features.
Alongside hands-on engineering, I bring experience in technical leadership, mentoring and continuous process improvement helping teams deliver cleaner architectures, better code quality and predictable release cycles.
Key Achievements
- Design, integration, and profiling of the MCP server and AI-chat using SSE and custom (safe!) router for LLM providers.
- Led end-to-end development of a multi-chain non-custodial launchpad (EVM + Solana), implementing deterministic token issuance flows.
- Architected a unified wallet abstraction layer across MetaMask, WalletConnect, Phantom, and Solflare, ensuring seamless cross-language interactions and cross-ecosystem signing flows.
- Designed and implemented robust CI/CD pipelines achieving a 4x delivery improvement while maintaining strict security gates for wallet-related deployments. GithubAction, Docker, AWS (mostly EC2, RDS and S3 with CDN), CDK and Oracle with Terraform.
- Built a non-custodial browser extension and web wallet for the BitSong blockchain from scratch, featuring secure key handling and mnemonic generation.
- Integrated advanced supply-chain protection (LavaMoat, pnpm permission controls) to harden build pipelines against dependency attacks, critical for financial software. Used also StepSecurity and Socket.dev GitHub Actions and APIs for the analysis and warnings to prevent various attacks.
- Led multiple projects and teams simultaneously, handling both technical side and team management. Delivered meaningful improvements to products and workflow.
