01 / Profile

Engineering across AI systems and products.

I design and deploy production-grade AI systems—from RAG-based chatbots and personalization engines to end-to-end automation workflows. I focus on cost-efficient infrastructure, prompt engineering, and reliable, scalable applications with LangChain, LangGraph, and vector databases on AWS.

Applied AI Engineer

Nov 2025Present
  • Built and deployed an AI assistant for NewPaper's modular project management platform — enabling teams to query tasks, time logs, leave balances, and reports through natural language using RAG over internal product data.
  • Designed intelligent automation workflows across NewPaper's module ecosystem — auto-generating invoices from tracked hours, surfacing payslip discrepancies, and drafting team status summaries from task and time tracking data.
  • Integrated LLM-powered features into NewPaper Spaces and Chat — smart message summarisation, meeting note extraction, and context-aware notifications for managers and team leads.
  • Architected the AI backend using FastAPI, PostgreSQL, and vector search, with real-time streaming responses and role-based access control aligned to NewPaper's permission model.
  • Monitored and optimised AI system performance — latency, token usage, cost, and hallucination rates — through prompt engineering, retrieval tuning, and evaluation harnesses.

Software Engineer

Apr 2023Aug 2023
  • Engineered core modules of NewPaper's modular project management platform — building the team management, time tracking, and task assignment interfaces in React and TypeScript.
  • Developed the REST API layer in Node.js for real-time data across modules — time logs, leave requests, role-based access control, and reporting dashboards.
  • Built the NewPaper Spaces and Chat mobile apps for Android and iOS using React Native, Kotlin, and Swift, including native modules for push notifications and offline sync.
  • Integrated cross-module workflows — time tracking to invoicing, leave management to payslips — enabling teams to generate accurate financial documents from tracked data.
  • Shipped features through Agile sprints, from architecture and implementation to testing and deployment on AWS.
