Production AI systems, not demos. Most AI initiatives die between the prototype and production. We build the part that survives: retrieval pipelines on private infrastructure, agents with real tool use, and the guardrails, monitoring, and validation layers that let a legal, security, or compliance team sign off. What makes an AI feature production-ready. Useful AI is a system of retrieval, policy, evaluation, and observability, not simply a model endpoint connected to a chat box. Controlled access to knowledge. Retrieval and tool permissions are designed around source authority, user identity, and data boundaries so the model cannot simply see everything. Measured usefulness. Evaluation sets, acceptance thresholds, and human review paths turn “it seems good” into a release decision a product and risk team can own. Operable model behavior. Tracing, prompt and model versioning, cost controls, and fallback behavior make the system diagnosable after the demo ends. What we deliver: - Retrieval-Augmented Generation pipelines on private infrastructure. - Fine-tuning and deployment of open-source and commercial LLMs. - Agentic systems with tool use, function calling, and multi-step planning. - Prompt injection defense, guardrails, and output validation layers. - Model monitoring, drift detection, and retraining pipelines. How an engagement runs: Ground, Retrieval over your own content. Build, Agents, tool use, and prompt design. Guard, Injection defense and output validation. The result: A feature review will sign off, Evaluated on every change, with a record of what the model saw. The model sits behind one interface, so it stays replaceable. How engagements run. It starts with a paid assessment: Anything carrying real technical risk begins with a fixed-fee technical assessment, one to three days, producing a written findings document and a scoped fixed price for the build. Fixed price for defined scope: Once the scope is known from your systems rather than from a conversation, the build is priced as a fixed figure, with the assumptions it depends on written down alongside it. Monthly retainer for operations: Ongoing operational ownership runs on a monthly retainer against an agreed service level, so the cost of running a system is a number you can plan against. No hourly meters running against unknowns. Common questions: Q: Can sensitive data remain inside our environment? A: We design for the required boundary: private retrieval infrastructure, controlled integrations, least-privilege access, and deployment patterns appropriate to your data classification. Q: How do you reduce hallucinations and unsafe tool use? A: We combine grounded retrieval, constrained tool permissions, output validation, adversarial testing, and monitoring. No one technique is treated as a complete guardrail. Q: How do we know whether an AI feature is getting better or worse? A: Through an evaluation set built before the feature ships, run on every change. Without one you are relying on whoever tried it most recently, which is why teams end up unable to say if last month's prompt edit helped. Q: What does this cost to run once it is live? A: Inference cost follows usage, so the variable is how much context each request carries and how often retrieval runs. We model that during design, because the architecture that is cheapest to build is frequently not the cheapest to operate. Q: Can you work with the model or vendor we have already chosen? A: Yes. The model sits behind a single interface, so the choice is reversible and the rest of the system does not depend on it. If your existing choice is a poor fit for the workload we will say so, with the reasoning. Q: Will our legal and compliance teams be able to sign this off? A: That is what the guardrail, validation, and audit layers are for. We design for the questions those teams actually ask: what data reached the model, what it returned, who saw it, and what happens when it is wrong. --- Canonical page: https://www.expandware.com/solutions/ai-systems-engineering/ Site index for machines: https://www.expandware.com/llms.txt Full site text: https://www.expandware.com/llms-full.txt Expandware Private Limited.
