Canada's AI & Data Engineering Partner.
Specialized AI and ML engineering for Canadian enterprises and institutions. RAG systems, AI agents, MLOps, and data platforms. Based in Calgary. Working across Canada.
Canadian organizations are buying AI. Most don't have the people in-house to build it properly.
The work that actually matters — RAG systems, AI agents, production ML pipelines, data platforms that hold up under real use — requires a depth of specialization that is hard to hire for locally. The alternative is usually a large out-of-province consulting firm, a long statement of work, and a team you will never meet.
OnCallDC is the specialized option. Canadian-based, focused on AI and ML engineering, and built to ship things that work rather than hand over a report.
AI & ML Engineering
Specialized delivery across the AI and ML stack. From raw data to production models to natural language interfaces your team can actually use.
RAG & Semantic Search
Build retrieval-augmented generation systems that let teams query documents, databases, and institutional knowledge in plain language. No SQL required. Answers grounded in your actual data.
AI Agents & Automation
Design and deploy goal-driven AI agents that automate workflows, surface signals, and take action across your existing systems without constant manual oversight.
MLOps & Model Deployment
CI/CD pipelines for ML models, experiment tracking, model registries, and automated retraining schedules so models actually reach production and stay there.
Data Engineering & Pipelines
Design and build the ingestion, transformation, and data modeling layer that feeds your ML systems and analytics. Scalable, testable, and maintainable from day one.
Analytics Engineering
Semantic layer design, dbt transformations, and dashboard development that connects your data platform to decision-makers without a dedicated analytics team in the loop.
Vector Search & Embeddings
Embedding infrastructure, vector database setup, and retrieval optimization for semantic search, recommendation systems, and similarity-based use cases.
AI Infrastructure
GPU advisory and on-site data center operations for Alberta companies running AI workloads in colocation facilities.
GPU Cluster Advisory
Right-size GPU configurations for training versus inference workloads, audit utilization, and eliminate wasted compute spend across your Alberta colocation environment.
AI Infrastructure Assessment
Evaluate whether your facility or workload environment can support high-density AI compute including power density, cooling, networking, and operational readiness.
On-Site Data Center Operations
Smart hands, rack and stack, break-fix, and structured cabling across Alberta colocation facilities. Local presence. No travel delays.
Who We Work With
Any Canadian organization working with AI and ML, or trying to. If one of these situations sounds familiar, we can help.
Your data is siloed.
Enterprises · Institutions · Government
- Simple questions take days of analyst work to answer
- Documents, databases, and internal systems don't connect
- Staff need a data team just to get basic information out of the systems they already use
Your models aren't shipping.
AI Teams · Product Companies · Startups
- Models work in development but break under real traffic or real data
- No reliable process to retrain, monitor, or roll back models in production
- AI features keep slipping because the infrastructure to support them isn't there
Your AI budget is going to slide decks.
Any organization investing in AI
- Large consulting firms charging for strategy that someone else has to build
- Weeks into an engagement before you meet the person doing the actual work
- Recommendations that don't account for your specific data, stack, or constraints
Deep in the work.
Built in Canada.
OnCallDC is a Canadian AI and ML engineering firm with deep technical specialization and on-site operational capability. You get that depth without the layers of account management, status decks, and overhead that come with a large consulting practice.
Deep AI & ML Specialization
RAG pipelines, AI agents, MLOps, data engineering, and GPU infrastructure. This is what we do, not a service line added to a generalist dev shop.
Canadian-Based, Remote-Ready
Based in Calgary, working with clients across Canada. No offshore teams, no timezone surprises. On-site when it makes sense, remote when it doesn't.
Production-Focused
We build things that ship. From architecture through deployment and ongoing support, the goal is working systems in production, not a report to file away.
Cloud-Agnostic
We work across AWS, GCP, and Azure depending on what fits your data residency, budget, and existing stack. No vendor preference. No lock-in.
Built in Calgary.
Serving Canada.
Khush founded OnCallDC after spending years as a Machine Learning engineer in Calgary and watching the same pattern repeat. Canadian organizations were buying AI strategies from large consulting firms and getting PowerPoints. The actual build work still needed someone with deep ML and data engineering experience to do it properly.
OnCallDC specializes in the technical work that matters: RAG systems, AI agents, MLOps infrastructure, data pipelines, and analytics engineering. The team brings cloud-agnostic delivery across AWS, GCP, and Azure, plus GPU infrastructure and data center operations experience for organizations running AI workloads in colocation facilities.
Canada's AI market is maturing fast. We work with organizations across the country that want working systems, not a strategy document.
