Hi, I'm Oleg Putseiko 👋

⚡️ I am currently open to new career opportunities!

I am a Senior Software Engineer with 8+ years of development experience (7 years in commercial development), with a deep focus on Security and Infrastructure. I specialize in building high-availability systems, implementing robust security protocols, optimizing backend architectures, and automating deployment workflows.

🛡️ Core Expertise

  • Infrastructure & DevOps: Advanced experience with Docker, containerization, CI/CD pipelines, and system architecture migration (including ARM64/M2 optimization).
  • Security: Implementation of complex security measures, including TOTP, 2FA, and secure data handling protocols.
  • Frontend Development: Started my career as a frontend developer, which gives me a strong foundation in building intuitive user interfaces and complex client-side architectures.
  • Backend Architecture: Developing scalable and performant services using Node.js, NestJS, GraphQL, and Prisma.
  • Low-Level Programming: Deep understanding of system architecture and experience with Assembler, enabling fine-grained optimization and direct hardware-level interactions.
