What I'm looking for

I’m looking for a team where I can own end-to-end SaaS features—from database and APIs to React UI—while building real-time dashboards and AI-powered product experiences, shipped reliably in production.

I’m a Full-Stack Software Engineer with 8 years of experience building end-to-end web applications and SaaS platforms, progressing from Intern through Junior, Software, and Senior Software Engineer. At LetzChat, Inc., I lead full-stack development across React, Next.js, Node.js, Python, FastAPI, and Django, owning features end-to-end—from database schema to API to polished UI.

I ship production SaaS with real-time dashboards, authentication, and multi-tenant panels, including systems processing 300M+ events/month (Kafka, ClickHouse, BigQuery) and D3.js-powered analytics fed by WebSocket data. I’ve also built AI-powered live translation workflows (DeepL, Google Translate, OpenAI, Whisper AI, and RAG pipelines) and deployed services on AWS using Docker, Kubernetes, Terraform, and CI/CD.
