AI architecture and agentic AI consulting in Sydney
Dr Koliya (Dr Dinindu Koliya Wedanage) is a Sydney-based AI Architect and the Co-Founder & CTO of Coderra. He helps organisations design and ship production-grade AI: agentic AI systems, LLM platforms and RAG architectures, AI evaluation and governance, and the data platforms underneath them.
His work spans startups, enterprise and government, from Accenture Australia and ResetData to the Australian Government's Age Assurance Technology Trial. He holds a PhD in Data Science from the University of Wollongong.
Agentic AI system development
Dr Koliya designs and builds multi-agent systems with planning, tool use and orchestration, with evaluation and guardrails designed in so they behave reliably in production.
Delivered
- At Coderra, leads the architecture of an agentic platform that reasons over business data and automates multi-step workflows, with LLM/RAG, evaluation and observability built in.
- Owns Coderra's end-to-end technology strategy: product architecture, agentic workflows, integrations and data pipelines.
AI architecture consulting
Architecture and strategy for scalable, secure and sovereign AI infrastructure, with evaluation, observability, privacy and compliance built in from day one.
Delivered
- As AI Architect at ResetData, steered AI presales for AI-F1, Australia's first sovereign AI supercomputer, on high-density NVIDIA H200 clusters alongside NVIDIA and Dell.
- Enabled enterprise AI through ResetData's AI Marketplace of live, NVIDIA-certified models.
LLM platform development and RAG architecture
Building and operating LLM-backed products: prompting, routing, retrieval, grounding and citations, with cost and latency control at scale.
Delivered
- Leads LLM and RAG architecture for Coderra's products, AISO and CommOps.
- At Sonder, built GPT-based NLU, classification, topic extraction and semantic search over large chat-transcript datasets on Databricks and Snowflake.
AI evaluation and observability
Evaluation frameworks and observability designed in from the start, so an AI system can be measured, governed and improved once it is live.
Delivered
- As Principal Data Scientist at the Age Check Certification Scheme, built the evaluation framework for the Australian Government's Age Assurance Technology Trial, covering reliability, privacy and inclusivity.
- Evaluation and observability are part of the stack he owns end-to-end at Coderra.
AI security and reliability
AI systems built to be deployed, measured, governed and improved, with security and reliability treated as part of the design, not an afterthought.
Delivered
- Integrated global standards into age-assurance testing, improving the functional suitability and security of age-verification technologies.
- Owns security and reliability as part of Coderra's technology strategy.
Data and ML engineering
Pipelines and ETL/ELT across GCP/BigQuery, AWS, Databricks and Snowflake, plus forecasting, NLP and predictive models that turn data into decisions.
Delivered
- At Accenture Australia, built and deployed ML models on Vertex AI with BigQuery analytics and GCP data pipelines.
- At the SMART Infrastructure Facility, established ETL/ELT processes and developed ML, deep-learning and time-series models in Python, R and SQL Server.
- Published peer-reviewed research on forecasting healthcare cost in Australia from health insurance claims data (IEEE, 2021).
Intelligent automation
Automating customer and operational workflows, including conversational messaging and SMS agents that respond to real demand.
Delivered
- At Accenture Australia, integrated Contact Center AI (CCAI) using natural language understanding.
- At nCinga Innovations, built industrial IoT products for smart factories: real-time insight, predictive analytics and automation.
AI Search Optimisation and AI-powered communication operations
These two services are delivered as products by Coderra, where Dr Koliya is Co-Founder & CTO and drives both product verticals.
How Dr Koliya works
- Production first, end to end: he reasons about the model, the data, the system around it and the business it serves.
- Governed and observable: evaluation, observability, security and reliability are part of the design, not an afterthought.
- Grounded in real delivery across startups, enterprise and government.
- Also available for lecturing, workshops and CTO or founder advisory.
