What I'm looking for

I’m seeking senior engineering roles building reliable, observable real-time platforms with strong security, accessibility, and fast incident diagnosis.

I am a Senior Full-Stack Engineer with 10+ years delivering real-time operations consoles and secure platforms using React, Vite, TypeScript, and Node/Express. I prioritize reliability, accessibility, and fast diagnosis workflows while standardizing UI patterns and telemetry.

I have led end-to-end delivery of dense operations consoles, architected WebSocket/Socket.io real-time pipelines, and owned PostgreSQL schema evolution with Drizzle ORM to sustain multi-tenant performance under bursty telemetry. I’ve implemented authentication/session hardening, audit-ready logging, secure file handling with Multer and AWS S3, and integrated operational notifications via AWS SES.

I am experienced across observability and reliability tooling (Grafana, structured logs, tracing concepts), performance tuning, and build-quality improvements (ESBuild, strict TypeScript checks). I focus on designing predictable UX under intermittent networks and maintaining least-privilege, auditable systems for regulated workflows.
