FULL STACK ENGINEER / BACKEND FOCUSED
From an idea
to production.
I’m Naveen. I build APIs, distributed services, and AI-powered
workflows—and take responsibility for how they run in production.

01 / SELECTED WORK
Systems I’ve helped
bring to life.
Selected production work at CO2OPT and a personal project.
Descriptions focus on my contributions.
01CO2OPT / AI & BACKEND
AI that connects
to real workflows.
An application assistant that turns natural-language requests into
validated backend operations.
OpenAITool callingMCPJWT
What I built
Built the assistant from scratch, mapped user intent to
application actions, and extended it with MCP so AI clients could
access backend capabilities through JWT-authenticated endpoints.
Why it matters
Multi-step application workflows become conversational
interactions, with controlled access to application data and
operations.

02CO2OPT / DOCUMENT PROCESSING
Documents into
application data.
Built OCR workflows with AWS Textract and connected extracted
information to backend services and business workflows.
Engineering contribution
Integrated document extraction with existing application
services, carrying extracted data into downstream workflows
rather than leaving it as isolated OCR output.

03CO2OPT / ASYNCHRONOUS SYSTEMS
Work that keeps
moving in the background.
Designed queue-based processing for email and application
workflows, with retries, failure handling, and operational alerts.
Engineering contribution
Used BullMQ and AWS SQS/SNS for asynchronous processing, and
built visibility into production systems through ELK and
Grafana.

financial signals together through Zerodha Kite MCP and REST
integrations.
