FIELD REPORT #002

I track my spendings with AI

Here's what actually happened


WHAT I WANTED

  • Track spendings without manually typing every item

WHAT I DID

  • Saved bill & invoice photos in a folder
  • Saved bill & invoice photos in a folder
  • Used Claude Cowork + gave it access to the folder
  • Gave Claude a prompt: extract, categorise, calculate
  • Asked for savings rate + advice on where to cut

WHAT CLAUDE DID

  • Read all the bills and extracted the data
  • Calculated totals per category + saving rate
  • Gave advice on where I spend most
  • Done in under 5 minutes

WHAT IT NEEDS FROM YOU

  • Photos of your bills
  • A bit of organisation upfront

FIELD REPORT #003

300 photos. One supplier code
Two AI tools.

Here's what actually happened


THE TASK

  • Identify labels from one specific supplier
  • across 300 photos
  • Each label has an unique supplier code

WHAT I DID WITH COPILOT

  • Wrote a prompt explaining exactly what to find
  • Added a reference photo showing where the code appears
  • Uploaded photos manually — max 20 at a time
  • Repeated the process in batches

WHAT WORKED

  • Identified the right labels with the supplier code
  • Saved time vs checking 300 photos manually
  • Likely caught labels I would have missed myself

WHAT DIDN'T

  • 20 photo limit — manual batching took time
  • Gave extra info I didn't ask for — too much text
  • Still had to manually search files by name in the folder

WHAT CLAUDE COWORK WOULD HAVE DONE

  • Give it folder access — no manual uploading
  • Run the prompt across all 300 photos at once
  • Return only what I asked — clean, no extra text
  • Tell me how many photos matched
  • Sort matching photos to the top of the folder
  • Done. Move on to the next task.

THE INSIGHT

AI should protect your mental capacity

Copilot helped. But I was still managing the process. With the right tool + folder access, I run one prompt and use my brain for decisions - not for file hunting.

Building a reliable counterfeit detection system at scale

Architecting a Multi-Layer Detection Solution to Protect Billions in Annual Value

Background

Background

This is a global authentication initiative protecting billions in annual supply chain value.

The system includes a Mobile App used by field inspectors, a web platform for the identification team, and Counterfeit Analysis—an ML-powered tool that detects counterfeit products from uploaded photos.

My work:

  • Drive product evolution of the counterfeit detection ecosystem.
  • Identify system gaps between operational reality and technical assumptions.
  • Define integration strategy across ML systems, rule engines, and enterprise databases.
  • Coordinate vendor evaluation and technical feasibility discussions.
  • Redesign workflows and UX based on field-user behaviour.
  • Prioritize phased delivery under budget and organizational constraints.
  • Align stakeholders across IT, Legal, Logistics, and Product teams.

The team includes compliance, legal, technical, and operational stakeholders. Together, we're protecting global markets.

Strategy

Reduce Friction, Increase Impact

The strategy is to reduce friction in the field application so teams can verify more products, allowing the field application to filter genuine products at scale while the identification team focuses only on high-risk counterfeit cases.

Result: Higher volume from the field. Better signal from the desk.

System

The Counterfeit Detection System: How All System Connect

System Architecture: The mobile detection platform integrates 6+ data sources and operational systems.

Key Challenge: coordinating complex integrations across organisational boundaries while maintaining a single, unified user experience.

Mobile APP

Mobile APP Functionality

Verify products, identify inconsistencies instantly. The system filters genuine items from suspicious ones, so your team focuses only on real threats—protecting billions in supply chain value.

Challenges

  • Detection engine built on false assumption: Expected all labels to have unique serialisation codes. In reality, 70% of supply chain lacks this data.
  • System fragmentation: Mobile app isolated from authoritative product database; only 30% data access.
  • UX friction: Users complained app was "too slow," "too complex," "not intuitive"—eroding trust.
  • Organisational blockers: Vendor coordination impossible without contracts; escalations hit limits.

Solutions

  • System 1: Connect app directly to authoritative product database → expand validation from 30% to 70%+ coverage.
  • System 2 layer: Add encryption as alternative authentication (independent of serialisation).
  • Phased UX redesign: Phase 1 (quick wins: clearer hierarchy, missing actions). Phase 2 (full simplification—ship within budget constraints).
  • Stakeholder alignment: Mapped hidden stakeholders; ran workshops to align on changes.

Mobile APP: Detection Engine

Detection Engine build on incomplete assumptions

Detection Engine "Perfect Life"

The detection engine was built on an assumption: that complete product identification data would be universally available across the supply chain.

Detection Engine "Real Life"

Legacy products: Many items in circulation lack modern identification markers.
Inconsistent adoption: Even when identification systems exist, implementation varies.
Data availability gaps: Significant portions of the supply chain lack complete data.

Why the original approach failed

When I took over, this challenge had been identified by my predecessor. The initial strategy was to pull comprehensive product data from the identification system.

However, investigation revealed the system only generates codes—it doesn't store product information. The strategy was based on false assumptions about system capabilities.

During stakeholder alignment sessions, the operations team suggested connecting directly to the master reference database instead—the actual authoritative source.

Lessons

Don't assume what systems can do. Investigate the actual capabilities.

Mobile APP: UX Audit

From User Feedback to UX Audit to Clarity

During my early months, I discovered previous user research that hadn't been acted upon. I conducted a comprehensive UX audit.

The diagnosis was clear. Implementation proved harder.

Users' Response

  • Interface Not Intuitive
  • Excessive information on screen
  • Workflow too lengthy and time-consuming
  • Reliability concerns (confirming detection engine issues)

UX Audit

  • Main screen overwhelmed with features: 7+ information categories with no clear hierarchy. The core goal was to analyze as many items as possible, but the interface gave equal weight to all features.
  • Disconnected information: Product data and analysis results were in separate sections with no visual connection—users couldn't trace which results matched which products.
  • Redundant navigation: Workflows required unnecessary steps and confirmation screens.
  • Missing resolution action: The completion action was buried in an optional initial step—resulting in unresolved cases piling up.

Simplifying the Workflow

My redesign focused on streamlining the analysis process and reducing complexity.

UI: From Complexity to Clarity

Constrains I am working within:

Budget: given to this constrain, I design a 2-phase UX rollout.
Team Lead resistance: Initially said UX was fine, app didn't need "fancy UI"
My response: Showed user survey data, framed as usability not aesthetics
Result: Agreed to 2-phase UX rollout.

Additional Security

Managing External Vendor Coordination

Additional Security Feature: Building Defence-in-Debt

ASF is an encryption solution being integrated to add invisible security markers to labels.

ASF will be integrated into the Mobile APP, allowing field inspectors to use encryption-based authentication alongside the existing validation system when scanning labels.

ASF integration diagram

Third-Party Integration Constraints

Implementing the encryption solution required coordinating between multiple external vendors. Organisational policy required formal governance structures rather than direct vendor communication, creating workflow constraints.

How I Managed It

I accepted the organisational constraint and adapted:

  • Documented all technical questions clearly to minimise misunderstandings
  • Tracked feasibility blockers explicitly so leadership owned the delay decision
  • Focused my energy on parallel work-streams: maintained momentum on Master Data integration and UX redesign (independent initiatives)
  • Kept the project moving despite the vendor coordination limitation

Key Learning: Not all blockers are solvable by individual PMs. Some require leadership decisions. My job was to make constraints visible, propose solutions, and execute within the boundaries leadership set.

Insights

Key Product Insight

The core challenge was not model capability alone, but the mismatch between system assumptions and real-world operational conditions.

Improving detection required rethinking data availability, workflow design, integration architecture, and organizational coordination together — not as isolated technical problems.
