Summary
👤
Senior🎓
Top SchoolSteven Passynkov is a cyber security engineer and full-stack developer with 8 years of hands-on experience building serverless, AI-driven, and user-centric applications across React, Node.js, Python, Java, and AWS. He blends security-first DevOps work—ECS, EC2, cross-account, VPC, Terraform, Veracode—with front-end UX and API security, delivering production systems from leasing engines to appointment platforms. Steven has built AI-powered voice systems and multi-agent solutions using Dialogflow, Gemini, LangChain, AgentCore, and OpenSearch, and he integrates ML into products rather than treating it as an afterthought. His background includes payment integrations with Square and Stripe and custom services on DocumentDB/MongoDB and DynamoDB, showing comfort across databases and cloud primitives. Based in Vaughan, Ontario, he started self-teaching software as a child and brings that energetic, do-it-yourself curiosity to both personal projects and enterprise engineering. A practical tinkerer who moves rapidly between research prototypes and secure, auditable deployments, he thrives where AI, UX, and cloud security intersect.
