Domain-specific legal model that stopped hallucinating citations

The Problem

A major international law firm was running general-purpose models that hallucinated citations and produced inconsistent clause analysis across 11 jurisdictions. Every wrong answer was a liability risk in client-facing work.

What We Built

We fine-tuned Gemma 3 27B on 400,000 of the firm's own legal documents using QLoRA on GCP Vertex AI. DPO alignment sharpened precision for time-pressured lawyers. A custom evaluation pipeline covering ROUGE-L, BERTScore, and citation accuracy ran before any model reached production.

91%Citation accuracy on legal queries

0Hallucinated citations after alignment

27BParameter model on 400K proprietary docs

60%Lower inference cost vs proprietary APIs

"What sets Jillani SofTech apart is the ability to turn complex regulatory requirements into a system that actually runs. Most vendors talk about compliance. These engineers build for it."

One governance layer for five production models in a regulated FinTech

The Problem

Five AI models were running in production with no shared visibility, no drift detection, and no governance. Model behavior was tracked by hand in spreadsheets. In a regulated financial environment, that is an audit failure waiting to happen.

What We Built

A single LLMOps control plane across all five models: scheduled automated evaluations, statistical drift detection against rolling baselines, shadow deployment and A/B testing before any version reaches live traffic, and a full model registry with SOC 2 compliant lineage and approval workflows.

5Production models unified under one platform

AutoDrift detection replacing manual review

SOC 2Audit-ready model lineage for compliance

3xFaster safe promotion via shadow testing

"The systems are solid, the documentation is thorough, and the team stayed accountable well past the delivery date. That mix of technical depth and post-launch ownership is rare at this level."

An autonomous revenue layer that closed the gaps no rep could watch

The Problem

Fourteen disconnected sales tools, no consistent lead qualification, and shaky CRM data. Revenue was slipping through gaps that no single person could track across multiple regions at once.

What We Built

A round-the-clock revenue layer on n8n and LangGraph. Real-time lead qualification, automatic CRM enrichment, personalized outreach across email and LinkedIn, predictive deal health scoring, and live pipeline reports delivered to leadership with no sales ops in the loop.

48%Reduction in manual sales ops workload

HealthcareUSAAgentic RAG · GCP Vertex AI · HIPAA

HIPAA-compliant clinical decision support for a hospital network

The Problem

A US hospital network had patient records, lab results, and ICD mappings sitting in silos, none of it reachable at the point of care. Clinicians needed decision support without adding friction to already demanding workflows.

What We Built

A HIPAA-compliant clinical platform on GCP Vertex AI using a hybrid Agentic RAG pipeline. Patient records, lab data, and medical literature unified into one queryable layer. Role-based access across every clinical and admin role, a full audit trail on every response, and a zero-downtime SLA.

91%Factual accuracy in clinical responses

27%Reduction in patient onboarding time

48%Less manual clinical documentation

HIPAACompliance built into the architecture

"The mix of factual accuracy, HIPAA-compliant architecture, and real-time performance had a direct, measurable effect on both patient care quality and throughput across our network."

Enterprise SaaSUSA and UKLangGraph · RAG Fusion · Neo4j

Knowledge search that handles multi-document reasoning at scale

The Problem

Critical institutional knowledge was scattered across hundreds of documents and disconnected systems. A single-vector-search setup had already failed. The organization needed multi-document, multi-hop reasoning that held up under real query volume.

What We Built

Multi-agent reasoning with a Neo4j knowledge graph for complex cross-document queries. RAG Fusion lifted precision well above single-retrieval approaches. Role-based access with a complete audit trail across every department, handling 8,000 queries per day at launch.

54%Faster knowledge retrieval

61%Better retrieval precision vs prior tooling

E-CommerceUSA and UKn8n · Claude Sonnet · GPT-5

Support that handled growing volume with flat headcount

The Problem

A fast-scaling US e-commerce brand had support infrastructure buckling under volume. Response times were slipping, agents were overwhelmed, and brand content across five social platforms was inconsistent. Hiring more people was not the fix.

What We Built

An autonomous support platform across Instagram, TikTok, Facebook, LinkedIn, X, chat, and email. Claude Sonnet handles incoming queries with knowledge-grounded reasoning, processing refunds, routing tickets, and resolving most issues without escalation. A sentiment layer escalates only what needs human judgment.

61%Queries resolved without escalation

44%Reduction in average response time

RegTechGermany and EUAgentic RAG · Azure OpenAI · LLMOps

Regulatory intelligence across eight countries and three languages

The Problem

A major European enterprise was managing GDPR, EU CSRD sustainability mandates, and internal policy review across eight countries at once. Each compliance cycle pulled in outside legal consultants and burned months of manual effort.

What We Built

A platform that monitors regulatory feeds across every relevant framework, analyzes internal documents for compliance gaps in real time, raises risk flags with structured remediation steps, and produces board-ready reports in English, German, and French on demand. An LLMOps governance layer keeps every decision auditable.

84%Accuracy in automated gap classification

DevOps and EngineeringUSALangGraph · AutoGen · GPT-4o

An engineering org that shipped faster by spending less time fixing the pipeline

The Problem

An engineering organization was spending more capacity managing its delivery pipeline than shipping product. Debugging was reactive, the same failure patterns kept returning across sprints, and incident postmortems were inconsistent when they happened at all.

What We Built

A multi-agent platform that plugs into the existing DevOps toolchain. It reviews pull requests before merge, diagnoses pipeline failures with specific fixes, generates validated patches and test cases, watches deployments for anomalies, and writes structured incident summaries after every significant event.

38%Less debugging and incident resolution time

29%Faster deployment cycles across environments

FewerProduction regressions per sprint

Program governance that flags risk before it escalates

The Problem

A global enterprise running complex programs across multiple regions had no real-time view of execution. Status updates were manual summaries from people with a stake in how they read. Risks surfaced only after they had escalated, and dependencies lived in spreadsheets that were stale before leadership saw them.

What We Built

A program management layer that ingests live communication from Slack, email, and ticketing. It tracks timelines and blockers as they develop, raises predictive risk flags before they escalate, and produces clean executive briefings on demand. A persistent decision-memory layer preserves context across leadership changes.

28%Improvement in on-time delivery

Two compounding problems solved in one platform: conversion and inventory

The Problem

Conversion was flat because the experience was identical for every segment. Inventory costs kept climbing because demand planning was reactive and manual. Two problems feeding each other, neither one solved by the existing tools.

What We Built

A dual-layer platform. The personalization layer generates real-time recommendations from live behavioral signals and improves through reinforcement learning. The supply chain layer predicts demand shifts and adjusts inventory planning before overstock or stockout hits. Both run through AWS Bedrock under 100ms.

14%Increase in e-commerce conversion rate

A voice agent that handles most of the tier-1 queue without a human

The Problem

A support organisation was carrying a large tier-1 call volume of repetitive, well-understood questions. Hold times were the main driver of customer dissatisfaction, and the queue peaked at exactly the hours when staffing was hardest. Previous attempts using conventional IVR menus had pushed callers to press zero immediately, which made the problem worse rather than better.

What We Built

A real-time voice layer on GCP with streaming speech recognition, retrieval grounded in the client knowledge base, and a policy layer that decides what the agent may resolve on its own. The hard constraint was latency: anything above about a second of silence reads as a broken call, so the whole loop is budgeted end to end and measured at the caller's ear rather than at the API. Low confidence, an explicit request for a person, or any topic outside the approved list triggers a warm transfer with the full transcript attached.

A private LLM deployment where no request ever leaves the customer environment

The Problem

A regulated enterprise wanted the capability of a modern language model over its internal documents, and had a contractual prohibition on sending that content to a third-party processor. Commercial API terms, including zero-retention agreements, did not clear the bar because the data still crossed an organisational boundary. The internal position was that the project could not proceed unless nothing left the environment at all.

What We Built

A fully private deployment inside the customer VPC. Open-weight models served on GPU nodes the client owns, a self-hosted vector store, self-hosted orchestration and self-hosted observability, with egress to external model APIs blocked at the network layer rather than by policy. Retrieval, generation, logging and evaluation all run inside the boundary, so the audit answer to "where did this data go" is the same as the answer to "where does it live".
