Autonomous Multi-Agent Procurement & Invoice Reconciliation Engine

A production demonstration of four autonomous LangGraph agents that extract unstructured PDF line items, verify quantities in SAP ERP schemas, isolate discrepancy variances, and generate GL accounting ledger entries with human review only on high-value outliers.

TECHNICAL BOTTLENECK

Supply chain enterprises process complex, unstructured supplier invoices each month. Manual accounts payable workflows require staff to cross-reference document line items against purchase order tables, creating processing bottlenecks and error vulnerabilities.

ENGINEERED BLUEPRINT

OXELVO engineered a deterministic multi-agent state machine. Agent 1 parses and normalizes OCR layout data. Agent 2 checks purchase orders in the ERP. Agent 3 evaluates price and quantity variance thresholds. Agent 4 prepares atomic ledger commits while routing variances to human reviewers via an approval portal.

High-Throughput Regulatory & Compliance RAG Search Engine

A hybrid retrieval augmented generation search engine querying over 4,000,000 regulatory legal tokens with sub-second streaming responses, citation verification guardrails, and semantic query caching.

TECHNICAL BOTTLENECK

Compliance officers and legal advisors spend hours cross-referencing multi-jurisdictional financial regulations. Standard search tools either miss semantic nuance (keyword only) or risk hallucinated clause citations (generic consumer LLMs).

ENGINEERED BLUEPRINT

We designed a hybrid vector pipeline pairing dense semantic embeddings (Qdrant) with sparse BM25 keyword indices, combined via Reciprocal Rank Fusion (RRF). A cross-encoder reranking model scores the top candidate chunks before prompt assembly, guaranteeing accurate clause citations.

Multi-Tenant Enterprise B2B SaaS Platform

A scalable, production-grade B2B SaaS platform architecture. Engineered with PostgreSQL Row Level Security (RLS) for tenant isolation, Stripe metered billing integrations, and self-serve team management.

TECHNICAL BOTTLENECK

Consulting and service organizations often lack the software infrastructure to convert proprietary manual workflows into scalable subscription products without risking tenant data leakage or billing edge-case failures.

ENGINEERED BLUEPRINT

OXELVO engineered a production SaaS blueprint built on Next.js App Router and PostgreSQL with kernel-level Row Level Security policies. Features automated customer onboarding, metered usage billing via Stripe webhooks, and an administrative control portal.

Real-Time Telemetry & Event Ingestion Pipeline

A distributed event-driven ingestion pipeline designed for handling high-volume telemetry payloads per second with sub-second analytical dashboard updates, predictive anomaly alerts, and automated failover.

TECHNICAL BOTTLENECK

Hardware sensors and industrial devices produce continuous streams of vibration, heat, and power telemetry. Traditional relational databases struggle under sustained event spikes, causing payload drops and delayed anomaly notifications.

ENGINEERED BLUEPRINT

We engineered an ingestion architecture around Apache Kafka and ClickHouse columnar storage. Lightweight FastAPI gateways publish incoming HTTP/gRPC telemetry to partitioned Kafka topics, while background workers batch-insert records into ClickHouse for sub-second analytical queries.

AI-Powered Adaptive Learning & Campus LMS Platform

An intelligent campus management and learning portal integrating automated assignment grading, rubric-aligned feedback generation, code sandboxes, and early student intervention analytics.

TECHNICAL BOTTLENECK

Educational institutions struggle with overloaded grading queues, delayed assignment feedback loops, and fragmented student engagement data across disparate legacy portals.

ENGINEERED BLUEPRINT

OXELVO engineered a modular educational platform pairing Next.js streaming user interfaces with localized LLM evaluation pipelines. Teachers configure deterministic grading rubrics while students receive instant, actionable feedback in sub-2 seconds.

HIPAA-Compliant Telemedicine & Sovereign Clinical EHR Platform

A secure, HIPAA-compliant clinical care orchestration platform with automated speech-to-text EHR charting, encrypted video consultations, and FHIR interoperability adapters.

TECHNICAL BOTTLENECK

Physicians spend up to 40% of patient consultation time documenting unstructured notes into rigid EHR databases, leading to burnout and delayed patient care records.

ENGINEERED BLUEPRINT

We designed a sovereign clinical AI gateway. Consultations are transcribed locally, stripped of protected health information (PHI) via Pydantic validators, and structured into FHIR-standard clinical encounters directly committable to EHR systems.

Headless High-Concurrency E-Commerce & Multi-Warehouse Sync

An ultra-fast headless e-commerce architecture engineered for flash-sale peak traffic, real-time multi-warehouse inventory reconciliation, and hybrid vector search recommendations.

TECHNICAL BOTTLENECK

Monolithic e-commerce storefronts suffer slow page load times, checkout lock contention during flash promotions, and out-of-sync inventory across physical stores and online channels.

OXELVO engineered a headless Next.js App Router storefront deployed on edge infrastructure, paired with an idempotent inventory reservation pipeline running on Redis and PostgreSQL.
