Custom LLM Solutions & Consulting

Applied NLP Architecture
for Human Language Data

Organizations sit on mountains of unstructured text — interviews, clinical notes, survey responses, customer logs. I bridge cutting-edge academic NLP with practical LLM engineering to transform complex language into reliable, structured insights.

Common Use Cases

Most data science tools are built for numbers; I build tools for human language. I help teams across various sectors automate their text-analysis bottlenecks.

Qualitative Research & Survey Coding

Automating or accelerating analysis of interviews, open-ended survey responses, focus groups, and qualitative corpora — extracting themes, arguments, needs, emotions, or domain-specific codes while preserving validation against human judgment.

Clinical, Behavioral & Health Text Analytics

Extracting structured psychological or clinical indicators from patient narratives, intake forms, therapy transcripts, or health questionnaires — with strict emphasis on privacy, expert validation, and careful interpretation.

UX, Product & Market Research

Turning user interviews, usability notes, feature requests, and market research responses into structured insights: taxonomies of user needs, pain-point clusters, decision-relevant themes, and representative evidence from the raw text.

Operations & Customer Experience

Processing high volumes of public inquiries, user feedback, or customer support logs to automatically classify intent, cluster recurring complaints, and route issues — at scale.

Institutional Knowledge & Procurement

Distilling actionable insights, efficiency metrics, and structured metadata from messy meeting minutes, vendor reports, and dense corporate documents.

Two Project Tracks

Whether you know your architecture or simply know you have a textual data problem, I structure projects into two tracks based on data scale, privacy requirements, and task complexity.

Track 2

Custom Model Engineering & Private Deployment

Best for: Organizations dealing with highly sensitive data (medical, corporate IP), extreme domain-specific jargon, complex coding schemes, or massive text volumes where commercial API costs are unsustainable.

The Methodology: Efficient Fine-Tuning (PEFT/LoRA). We train a compact, open-weight model (Llama, Qwen, or Mistral) on your private datasets so it masters your specific textual domain.

  • Data Privacy & IP Ownership: Custom model weights you own completely — sensitive data never leaves your servers.
  • Cost Reduction & Tone Adaptation: Slashing cloud API costs while embedding your organizational style or clinical coding scheme directly into the model's architecture.

Methodological Validation

Regardless of track, the validity of the data is everything. Every NLP pipeline is built and validated to a rigorous academic standard so that stakeholders, clients, and peer-reviewers can fully trust the results.

01

Gold Standard Comparison

Systematically testing and tuning the model against your gold-standard data (e.g. human-labeled annotations) to ensure maximum accuracy on your specific task.

02

Statistical Reliability

Measuring performance using accepted statistical agreement metrics to prove the automated pipeline is as consistent and reliable as human experts.

03

Augmented Evaluation

Optionally supplementing human validation with "LLM-as-a-Judge" workflows, using secondary models to score text or monitor compliance against your specific rubrics.

From First Call to Delivery

You do not need to have the architecture mapped out before we speak. Start with your data problem.

1

Data Discovery

We start with a brief scoping call and a sample of your raw data. I provide a preliminary assessment of what can be extracted and an estimation of the expected baseline accuracy range.

2

Fixed-Scope Execution

I operate on a project-based, fixed-price model. You know exactly what the pipeline will cost and what deliverables you will receive before work begins.

3

Delivery & Handoff

You receive the fully annotated datasets, the trained model weights (if applicable), and the methodological documentation required for your internal stakeholders or academic publications.
