The HealthTech Engineer’s 2025 Cherry-Pick: Building HIPAA-Compliant Telemedicine & EHR Software That Scales
October 1, 2025How ‘Cherrypicking’ Undervalued Tech is Accelerating Automotive Software Innovation
October 1, 2025Technology is reshaping the legal field, especially in E-Discovery. After spending years building and advising on LegalTech platforms, I’ve seen firsthand how the right development principles can create software that’s not just faster—but smarter.
Why “Cherrypicking” Matters in LegalTech
In rare coin collecting, a “cherrypick” means spotting what others miss: a subtle mint mark, a date overprint, or a flaw that makes a coin worth far more than its face value. The same mindset applies to LegalTech and E-Discovery. The best platforms don’t just process documents—they find the details that change cases.
I’ve spent the last decade working with law firms and developers to build E-Discovery tools. One truth stands out: the best legal software doesn’t just automate—it cherrypicks. It spots the metadata quirk that reveals a forged signature. It catches the footnote with a non-standard arbitration clause. It flags the redaction that hides privileged content.
Here’s how the precision and instincts of rare coin collectors can shape the next generation of legal software.
1. Precision in Document Review: The Art of the Anomaly
Why Most E-Discovery Tools Fail at Finding the “Hidden”
Take the 1951-S/S Buffalo nickel. It was misidentified for years because grading tools couldn’t spot the subtle repunched mint mark. Many E-Discovery platforms make the same mistake. They rely on surface-level metadata or keyword searches.
They miss the real gold: the date overprint, the duplicate clause buried in a contract, the redaction pattern, or a timestamp that doesn’t match the document’s creation date.
In litigation, these details matter. A single buried clause or misattributed signature can shift the outcome of a case.
But most tools treat every document the same. They don’t prioritize based on contextual anomalies—the digital version of a doubled die obverse (DDO) or overdate.
Actionable Takeaway: Build Anomaly Detection into Your Stack
To build software that finds what others miss:
- Use AI to detect formatting inconsistencies—font shifts, margin changes, metadata mismatches.
- Train models on “redacted pattern recognition” to identify when a redaction hides a privileged term.
- Implement document “fingerprinting” to flag duplicates or near-duplicates with subtle variations (e.g., a 0.2-second timestamp difference).

In a recent project, we used diff-based document comparison with semantic hashing to identify two versions of a contract. One had a non-standard arbitration clause—buried in a footnote. Our system flagged it as a “high-anomaly” document. The client used it to pivot their settlement strategy.
Code Snippet: Simple Anomaly Scoring in Python
import hashlib
import difflib
from datetime import datetime
def calculate_anomaly_score(doc1, doc2):
# Semantic similarity
similarity = difflib.SequenceMatcher(None, doc1.text, doc2.text).ratio()
# Metadata delta
time_diff = abs((doc1.created - doc2.created).total_seconds())
# Hash consistency
hash_1 = hashlib.sha256(doc1.content).hexdigest()
hash_2 = hashlib.sha256(doc2.content).hexdigest()
hash_diff = 0 if hash_1 == hash_2 else 1
# Anomaly score: lower similarity, higher time diff, hash mismatch
score = (1 - similarity) * 0.4 + (min(time_diff, 60) / 60) * 0.3 + hash_diff * 0.3
return score
# Flag documents with score > 0.6 for human review2. Legal Document Management: The “Grading” Problem
Why Grading Services Are Like Legal Document Review
Third-party grading services (TPS) like PCGS and NGC often miss overdates or doubled dies unless specifically asked. Many document management systems (DMS) do the same—they fail to “grade” documents unless manually tagged.
In E-Discovery, a document’s “grade” decides its priority:
- High-grade (MS67+): Directly relevant, unique, high-risk (e.g., incriminating email chain).
- Mid-grade (MS63): Contextually relevant, but not pivotal (e.g., routine policy doc).
- Low-grade (VG8): Irrelevant or duplicate (e.g., standard boilerplate).
Actionable Takeaway: Automate Document “Grading” with AI + Human-in-the-Loop
Stop relying on manual tagging. Use AI to:
- Predict relevance with NLP models trained on case-specific language (e.g., “confidential”, “breach”, “indemnification”).
- Score privilege risk using pattern recognition (e.g., “attorney-client”, “work product”, redaction density).
- Detect “population rarity”—how many similar documents exist in the corpus? A unique clause is a “top-pop” (like a MS67FS) and should be prioritized.
We built a “Document Quality Score” (DQS) engine combining:
- Relevance (BERT-based scoring)
- Privilege risk (custom NER model)
- Novelty (TF-IDF + clustering)
- Metadata consistency (anomaly detection)
The result? A 40% reduction in review time and a 22% increase in high-value document capture.
3. Building Software for Law Firms: The “Dealer” vs. “Collector” Gap
Most Lawyers Are Like Coin Dealers—They Don’t Know What They’re Selling
As one forum user put it: “Most dealers don’t care or check for varieties.” Sound familiar? Many law firms collect emails, contracts, and Slack logs—but don’t grasp the latent value in metadata, edit history, or access logs.
Your software must step in as the expert collector—not just the dealer.
Actionable Takeaway: Build “Expert Mode” Features
Include tools that:
- Auto-detect AI-generated content (e.g., watermark scanning, metadata checks).
- Flag “duplicate but modified” documents (e.g., two invoices with same PO but different amounts).
- Surface “access anomalies”—who viewed a sensitive file? When? From where?
- Identify “hidden relationships” between documents using graph analysis (e.g., two contracts signed by same person but with different terms).
We added a “Chain of Custody Radar” that traces every action on a document—downloads, prints, email forwards. If a privileged document was accessed by a non-legal team member, it’s flagged immediately.
4. Compliance & Data Privacy: The “Slab” in LegalTech
Grading Services “Slab” Coins—You Must “Slab” Your Data
When PCGS or NGC grades a coin, it’s not just scored—it’s sealed, verified, and authenticated. Legal data needs the same “slab”: provenance, immutability, and auditability.
Actionable Takeaway: Build a “Digital Slab” Framework
- Immutable logs: All document actions (view, edit, export) are cryptographically signed and time-stamped.
- Zero-knowledge redaction: Redacted content is encrypted, not just hidden.
- Access tiering: Role-based access with biometric or multi-factor authentication.
- Automated compliance tagging: Auto-flag GDPR, CCPA, or HIPAA-relevant content.
We use blockchain-based audit trails for high-risk cases. Every document action is written to a private chain. This helped one client pass a DOJ audit with zero findings.
5. The Future: AI as the Ultimate Cherrypicker
From Manual Search to “Predictive Cherrypicking”
The next wave of E-Discovery won’t just find anomalies—it will predict them.
Imagine an AI that:
- Learns from past cases to predict which document types are likely to contain privileged content.
- Flags “red flag” language patterns (e.g., “I think we should destroy this”) before review.
- Uses reinforcement learning to prioritize documents based on case outcome impact, not just relevance.
This is the future of LegalTech: an AI that doesn’t just process data—but collects it like a master numismatist.
Example: Predictive Anomaly Scoring
# Pseudo-code for predictive anomaly model
model = train_on_historical_cases(
features=[relevance_score, privilege_risk, novelty, metadata_anomaly],
labels=[case_impact_level]
)
# Predict "cherrypick potential" of new documents
prediction = model.predict(new_documents)
high_value_docs = [doc for doc, pred in zip(docs, prediction) if pred > 0.9]Conclusion: Build Legal Software That Finds the Hidden Value
The best LegalTech platforms won’t win by adding more features. They’ll win by cherrypicking like experts—finding the overlooked, the misidentified, the high-impact.
To build winning E-Discovery software in 2025:
- Detect anomalies like a numismatist spots a DDO.
- Grade documents with AI-driven "DQS" scores.
- Act as the expert, not just the tool.
- "Slab" your data for compliance and audit.
- Use AI to predict the next big "find" before it’s reviewed.
In a world where 95% of data is noise, the winners will be those who can find the 5% that matters. Just like the coin collector with the 1951-S/S or the 1855/54 overdate, success in LegalTech isn’t about volume—it’s about vision, precision, and timing.
The future of E-Discovery isn’t automation. It’s intelligent cherrypicking.
