Machine-learning engineer focused on the parts that actually decide whether ML works in production — evaluation, calibration, thresholds, drift, identity/fraud signals, serving, and the tooling around them. Also building production agentic systems: tool loops, MCP servers, streaming parsers, and agent memory.

Agentic & LLM infrastructure
| Repo |
What it does |
| tool-loop |
Correct agentic tool-use loop: parallel dispatch, error isolation, auto-schema from Python functions |
| mcp-quickserver |
MCP server template: tools, resources, and prompts with stdio and SSE transports |
| stream-parse |
Parse streaming LLM output: incremental JSON, markdown blocks, tool-call deltas, SSE events |
| agent-scratchpad |
Persistent vector memory for agents: embed, store, retrieve by cosine similarity |
| prompt-cache-bench |
Benchmark prompt caching: cache hit rate, latency delta, cost savings with real measurements |
| llm-eval-lite |
Assertion-based eval harness for LLM/agent outputs; composite checks (AllOf, AnyOf) |
| rag-eval |
RAG pipeline evaluation: chunking strategies, retrieval quality, answer faithfulness |
| llm-gateway |
Production Anthropic API proxy: token-bucket rate limiting, retry with backoff, cost tracking |
| rag-demo |
End-to-end RAG demo: BM25 + tool-loop agent + faithfulness eval + persistent memory |
ML evaluation & calibration
| Repo |
What it does |
| ml-eval-report |
Binary-classifier eval: metrics, ROC/PR + AUC, threshold sweep, Brier score, ECE |
| calibrate-ml |
Probability calibration: Platt scaling, isotonic regression, ECE, reliability diagram |
| thresholdkit |
Pick operating thresholds under precision / FPR / cost / expected-value constraints |
| rankeval |
NDCG, MRR, AP@K, P@K, R@K — ranking metrics for search, recommendation, RAG |
| Repo |
What it does |
| featurecheck |
Feature drift (PSI/KS/chi-squared) + schema/null/dtype validation |
| idgraph |
Identity/entity graphs from shared signals; surface synthetic-identity rings + risk scoring |
| pii-redactor |
Detect & redact PII (email, phone, SSN, IP, Luhn-validated cards); custom patterns |
| capture-qa |
Image capture-quality gates (sharpness, exposure, resolution) |
| modelcard-gen |
Generate Model Card markdown from a JSON config |
| Repo |
What it does |
| tps-bench |
HTTP throughput & p50/p90/p99 latency benchmark for serving endpoints; warmup + JSON output |
| cmsketch |
Count-Min Sketch: approximate counts over high-cardinality streams; merge + serialization |
