AI engineer building safer agents and imaginative products.
I’m Ronith Rashmikara, a Sri Lankan AI and software engineer working across agent safety, generative learning, fine-tuned language models, full-stack products, and immersive intelligent systems.
AI engineering projects and evidence
My recent work includes DataAgent-SafeBench, an open AI-agent safety benchmark with 120 controlled cases and 720 scored runs; Yume, a live generative language-learning world; and PersonaBench Aiko, a controlled character-model fine-tuning study.
I received the Best Presenter Award for the AI track at JASPER 2026 for presenting DataAgent-SafeBench.
- 720 scored AI-agent safety runs (120 cases × 3 open-weight models × 2 repetitions)
- 120 controlled benchmark cases
- Fine-tuned language-model research with held-out evaluation
- Live generative AI and immersive-web products
Start with the featured build, Project Alpha, then explore PersonaBench Aiko and KOI: Spirit Current.
Selected AI, software, and research work
Explore deployed products, research studies, live demos, public source code where available, technical decisions, and measurable outcomes.
Yume
A language-learning game on Visko Orbis: speak Japanese or English and the live world transforms, with quests, a sticker book, and a magic door.
DataAgent-SafeBench
A benchmark for authority confusion, prompt injection, and unsafe task escape in AI data agents, with a published v1.0.1 re-analysis.
Orbit Personal OS
A personal Android OS with local music streaming, audio-reactive artwork, daily planning, and private creation tools.
Project Alpha
A full-stack freelance marketplace with projects, bids, simulated escrow, reviews, disputes, and administration.
PersonaBench Aiko
A controlled LoRA fine-tuning experiment measuring character consistency against prompting baselines.
KOI: Spirit Current
A third-person browser experience inside an upside-down Gaussian-splat spirit garden.
Ceramic Road Journey
A rainy Gaussian-splat village adapted for browser delivery: 67 MB of splats down to a 2.47 MB default tier.
JASPER Textile Lab
A computational study of Japanese and Sri Lankan textile design DNA.
AI and full-stack engineer
I work across AI agents, machine learning, large language models, generative media, full-stack engineering, world models, and immersive web technology.
