Hi, I'm Aparna Pradhan

Applied AI Engineer · Agentic Systems · Enterprise AI Integration

I build AI systems for real business workflows — combining agentic reasoning with deterministic software, enterprise integrations, evaluation, reliability, and human oversight.

My interest is at the intersection of:

Applied AI × Systems Engineering × Business Operations

What I Build

I am particularly interested in AI systems that have to operate inside existing business processes, rather than isolated chat interfaces.

That means dealing with:

  • messy and heterogeneous data
  • APIs and enterprise systems
  • legacy infrastructure
  • ambiguous operational cases
  • business rules and policy
  • human approval
  • failure and recovery
  • security and authorization
  • evaluation and regression
  • measurable operational outcomes

My current work explores this through three different problem classes.


Engineering Philosophy

AI handles ambiguity. Deterministic software handles truth, authority, and execution.

LLMs are powerful reasoning components, but they should not automatically become the system of record, authorization layer, or source of truth.

I therefore design around explicit boundaries:

Principle What it means
Bounded agents Explicit tools, permissions, context, budgets, and state
Deterministic controls Validation, business rules, reconciliation, authorization
Evidence Important claims should be traceable to their source
Human oversight Humans retain authority where automation is unsafe or ambiguous
Verification Actions are independently verified rather than trusted blindly
Evaluation Golden cases, regression tests, adversarial scenarios
Observability Workflow state, traces, errors, latency, and AI telemetry
Failure-first design Retries, idempotency, timeouts, stale state, partial failure

The objective is not to make an AI system look autonomous.

It is to make it useful, bounded, observable, and reliable enough to participate in real operational workflows.


Current Projects

01 · FinSight

AI-assisted Financial Resolution

View Repository →

FinSight is a focused financial-resolution system modeled around a single B2B commerce company.

Its job is to:

Detect → Investigate → Explain → Propose → Authorize → Execute → Verify → Close

The system reasons across heterogeneous financial systems including:

  • payment-provider state
  • accounting records
  • expected settlement data
  • email and collaboration context
  • a legacy COBOL-style settlement boundary

Core boundary

The agent can:

  • investigate
  • gather evidence
  • generate hypotheses
  • correlate information
  • explain discrepancies
  • propose resolutions

The agent cannot:

  • establish financial truth
  • authorize its own action
  • bypass policy
  • execute arbitrary operations
  • verify its own execution

Current engineering work includes:

  • deterministic financial reconciliation
  • evidence-backed investigation
  • typed agent capabilities
  • authority boundaries
  • human resolution workflows
  • legacy batch integration
  • idempotent execution
  • adversarial evaluation
  • security and isolation
  • post-execution verification

Status: Active development


02 · ClaimOps AI

Evidence-Driven AI for Health-Insurance Claims Operations

View Repository →

ClaimOps explores how AI can assist claims operations while keeping adjudication authority with the insurer or TPA.

The core workflow:

Claim
  ↓
Document Ingestion
  ↓
Classification / Extraction
  ↓
Evidence & Provenance
  ↓
Deterministic Validation
  ↓
Exception
  ↓
Bounded Investigation
  ↓
Evidence-Grounded Finding
  ↓
Human Review
  ↓
Audit

AI is used for cognitive work

  • interpreting heterogeneous documents
  • investigating ambiguous exceptions
  • gathering relevant evidence
  • forming hypotheses
  • preparing findings

Deterministic software controls

  • validation
  • state transitions
  • authorization
  • evidence verification
  • workflow execution
  • auditability

The system is deliberately positioned beside the insurer's adjudication process rather than replacing it.

Current engineering work includes:

  • evidence-grounded agent tools
  • deterministic-first orchestration
  • durable workflow state
  • failure and retry semantics
  • tenant isolation
  • adversarial testing
  • evaluation harnesses
  • observability
  • human-review routing

Status: Active development


03 · OntologyAI

Business Discovery → Ontology → Workflow → Solution Design

View Repository →

OntologyAI explores the problem that comes before implementation:

How do you turn messy business context into a structured understanding of an organization, its processes, systems, and operational problems?

The core idea:

Business Context
       ↓
Domain Model
       ↓
Entities & Relationships
       ↓
Processes
       ↓
Operational Pain Points
       ↓
Solution Design

It focuses on the discovery and solution-design side of enterprise AI engineering.

Status: Experimental / evolving


The Common Thread

These projects are intentionally different.

They explore different business problems, data shapes, system constraints, and risk models.

But they share the same engineering principle:

Business Problem
       ↓
Workflow Understanding
       ↓
System & Data Mapping
       ↓
Deterministic Controls
       ↓
Bounded AI
       ↓
Human / Policy Boundary
       ↓
Execution
       ↓
Verification
       ↓
Observable Outcome

I am interested in where AI belongs inside a system — and equally, where it should not be trusted.

How I Engineer

I prefer an evidence-driven development loop:

RED Tests
     ↓
Implementation
     ↓
GREEN
     ↓
Integration Testing

PR
     ↓
Merge
     ↓
Evidence

A system is not complete because the happy path works.

I want to understand:

  • What happens when data is malformed?
  • What happens when the model is wrong?
  • What happens when a tool fails?
  • What happens when a request is duplicated?
  • What happens when evidence is missing?
  • What happens when state becomes stale?
  • What happens when an external dependency disappears?
  • What prevents an agent from exceeding its authority?

What I'm Working Toward

I am developing toward roles at the intersection of:

Applied AI · Agent Engineering · AI Solutions · Enterprise Integration · Forward-Deployed Engineering

I enjoy problems where the work starts with an ambiguous business process and ends with a working technical system:

Understand the business
        ↓
Map the workflow
        ↓
Understand the data
        ↓
Identify the real constraint
        ↓
Design the solution
        ↓
Build the system
        ↓
Integrate with existing infrastructure
        ↓
Evaluate it
        ↓
Deploy and observe it
        ↓
Measure the outcome

Beyond the Code

I am particularly interested in the question:

How do we make AI useful inside real organizations without pretending that probabilistic models are deterministic systems?

That's the engineering problem I'm exploring.


Let's build systems, not just demos.
