AI & Backend Systems Engineering — Consulting & Sprints

Production AI Workflows, Document Extraction & Low-Latency Backends.

I help fast-growing startups and enterprises turn messy unstructured documents into validated data pipelines, automate operational workflows, and eliminate backend latency bottlenecks.

Productized Engineering Sprints

Two Focused Ways We Can Work Together

Instead of vague hourly billing or lengthy recruitment cycles, I offer scoped, high-leverage technical sprints designed to solve critical bottlenecks in 1 to 2 weeks.

Sprint 01 • High-Impact AI Automation

Production AI & Unstructured Document Extraction

Tired of LLM prototypes hallucinating or failing when parsing customer PDFs, insurance claims, and invoices? I build deterministic multi-model extraction pipelines with strict schema validation, confidence scoring, and automated exception routing.

Core Deliverable
Production document ingestion API & webhook pipeline
Turnaround
10 to 14 business days
Key Tech
Python, OCR/Vision models, FastAPI, Redis, Postgres

Sprint 02 • Infrastructure & Latency

Backend Concurrency, Latency & Infrastructure Scale

When APIs lag under concurrent traffic or background job queues choke, you don't need a complete rewrite. I audit database query plans, implement Redis caching strategies, decouple synchronous bottlenecks into Celery/Pub-Sub workers, and harden deployment pipelines.

Core Deliverable
Latency profiling, query tuning & async worker architecture
Turnaround
7 to 10 business days
Key Tech
Django, FastAPI, PostgreSQL, Redis, Celery, Docker, K8s
