About
I'm Tanzir — an AI automation engineer based in Sydney, currently doing my Master's in AI at Macquarie University. Freelancing on Upwork since 2022, building agents and automation systems for clients worldwide.
Most recently at Sequesto BV (Belgium), building a SaaS platform automating enterprise tender workflows. Before that at VRSEN AI, where I cut hallucination rates ~40% with a production OpenAI Assistants integration.
I have a publication in review on natural language generation techniques, was runner-up at the Banglalink Hackathon 2024, and taught Python and web dev to 200+ students as a senior instructor at Codingal.
Off the clock: mechanical watches, mechanical keyboards, and systems that don't break at 2am.
Not sure if I'm the fit?
Don't guess.
Interview my AI.
The AI version of me knows my skills, experience, and projects — ask it anything, like a screening call without the calendar invite.
