AI & Automation

NullStack does not resell third-party AI platforms with a margin on top. Every pipeline we deploy is written in Python, version controlled in Git, and handed over with full source access at project completion. Our engineers have worked across FMCG procurement workflows, healthcare patient triage systems, and D2C order management stacks — sectors where the cost of an automation error is measured in compliance penalties or customer churn, not merely inconvenience. This cross-sector depth means we arrive at a new engagement already familiar with the failure modes your industry has already discovered. We deploy open-weight LLMs (Mistral 7B, LLaMA 3, Phi-3) on-premise using Ollama or vLLM, eliminating the per-token pricing exposure that makes OpenAI-dependent workflows economically unscalable at volume. Our automation orchestration runs on self-hosted n8n instances, giving clients a visual audit trail of every workflow execution. A D2C client we onboarded in Q4 2024 reduced manual order-processing hours by 73 percent within six weeks of deployment, with zero third-party data exposure. We scope every engagement with a process audit first — mapping friction points, error rates, and escalation paths — before committing a single line of code, because automation built on a broken process produces broken results faster.
