I've built AI-powered products at Payraydoo and researched efficient on-device language models at Atlassian. My work spans document automation, agentic AI, browser testing, and retrieval-driven systems.

At Payraydoo, I built document-parsing workflows with Vercel AI SDK and structured extraction across invoice and remittance formats. I improved the React, TypeScript, Prisma, and Better Auth upload experience, cutting manual handling by 40–50% and integration issues by 30%.

At Atlassian, I trained Qwen3 small language models through SFT, DPO, and GRPO with LLM-judge evaluation and guardrails. I raised PII-anonymization quality from 4/10 to 9.55/10 while optimizing inference for low-latency operations.

I've also built ReLink, an autonomous B2B marketplace using Gemini Vision and MCP-orchestrated agents, plus BrowserRun and VerifyIt for failure-driven testing and automated credibility checks. Outside product work, I serve as Vice President of iDEA Club and have earned hackathon recognition for projects in Web3, agentic AI, and generative AI.
