Client & Industry Overview

Our client’s HR team faced rising volumes of internal queries on policies, benefits, and compliance—all requiring manual lookup and response. Employees lacked a direct way to get reliable answers without digging through PDFs or intranet links. We developed a custom HR chatbot powered by GPT-4o and Elasticsearch with vectorized semantic search. It understands employee intent, fetches relevant clauses, and auto-deflects repetitive queries. For complex cases, it triggers a live-agent handoff and logs the full transcript for review. Role-based access ensures responses are scoped and secure.

Project Roadblocks

When Smart Chat Needs Smarter Boundaries

Intent Confusion in Overlapping Queries

Fine-tuning GPT-4o embeddings to differentiate vague HR intents like “leave rules” vs “leave application” required multiple RAG iterations.

Role-Based Access Filtering Errors

Applying correct response limits via SSO and RBAC without breaking query accuracy was a persistent cross-auth issue during development.

Clause-Level Search Accuracy Drop

Semantic matches worked well broadly, but clause-level retrieval accuracy dropped without ELSER-driven field-aware filtering and query parsing logic.

Escalation Timing Misalignment

Bot sometimes escalated chats too early or too late due to poor sentiment scoring calibration and missing fallback intent triggers.

Integration Sync with ServiceNow

Webhooks occasionally failed to sync ticket IDs or fetch updates due to timing mismatches in concurrent backend service execution.

The Solution

Strategy-Led AI Chatbot Optimization

Embedded Multi-Intent Recognition

To resolve ambiguity between overlapping HR queries, we trained GPT-4o embeddings on intent clusters and layered fallback prompts to improve routing accuracy across similar question patterns.

RBAC-Aware Prompt Injection

We built a dynamic prompt layer that injects user role and permissions into GPT inputs, ensuring answers remain scoped to the user's HR access profile without breaking intent alignment.

Clause Retrieval via ELSER

By integrating Elastic’s ELSER, we improved clause-level accuracy through sparse vector encoding, enabling the chatbot to retrieve specific content from complex HR policies and documents.

Escalation Logic Reprogramming

To avoid premature or delayed human escalation, we merged confidence scores and sentiment indicators, triggering escalation only when both thresholds signaled uncertainty or user dissatisfaction.

Retry Queues for Ticket Sync

We built retry queues for ServiceNow and Ivanti webhooks, ensuring ticket actions are retried on failure and synced reliably—even under variable API response conditions.

Faster Answer. Lighter Workload. Better Accuracy

HR Workload Reduction

Most repetitive queries are now self-served through the bot, reducing dependency on manual HR responses across departments.

Auto-Resolved Tickets

The system resolved most HR-level queries end-to-end without escalation, deflecting tickets and easing helpdesk volume.

Query Accuracy Rate

Combining GPT-4o and ELSER returned specific, clause-level answers to employee questions with minimal false positives.

3s Avg Response Time

Elastic indexing and vector matching returned answers within seconds—even under simultaneous multi-user load.

Zero Data Exposure Events

Role-based SSO filtering enforced scoped outputs, preventing access to out-of-bounds or sensitive HR content.

Positive User Sentiment Spike

Chat transcripts and dashboard showed a clear shift in satisfaction, with most users rating interactions as smooth and helpful.

Estate Planning / Legal ServicesEstate Planning Modernized with AI Automation

EZ Living Trust set out to modernize estate planning by moving away from manual, paper-based workflows. Built for aging adults and working families, the platform guides users through legal processes with clarity and automation. The original system involved offline appointments, human dependency, and disconnected document handling. With growing demand, the model became hard to manage and scale. Our solution: a digitized platform that systemizes case tracking, streamlines notary assignment, and delivers real-time user visibility—cutting support costs and operational bottlenecks.

Construction ManagementModern Construction Needs Modern Coordination - Swivu (Beta)

Managing multi-site construction projects with Excel, emails, and verbal updates had become inefficient and error-prone. Swivu Engineering needed a smarter system to track project status, assign tasks across departments, and monitor execution across all locations—without overcomplicating the daily operations for site workers. We designed a real-time project management platform that connects HQ and field teams through a browser-based control panel and a lightweight mobile app. The tool enables role-based collaboration, dynamic scheduling, async updates, and seamless sync across departments. Every task, timeline, and team is now connected with fewer bottlenecks and a lower margin for error.
