ForgeKV
A persistent key-value server built below the framework line.
A versioned binary protocol feeds a bounded TCP server and sharded in-memory index backed by checksummed, append-only segments. The engine handles TTL expiry, compaction, truncated-tail recovery, corruption detection, and process-level ownership of the data directory.
- 130 tests per Release and sanitizer configuration
- Two parser fuzzers at 10,000 runs each
- A focused TCP fix moved median p99 batch latency from 49.2 ms to 0.99 ms on the documented loopback benchmark

TalentScope
A search and retrieval service measured under a fixed CPU budget.
Celery workers ingest and embed job postings into PostgreSQL; FastAPI combines GIN full-text search with pgvector HNSW retrieval through Reciprocal Rank Fusion. Redis coordinates queues, in-flight claims, answer caching and spend controls, while readiness gates model-backed routes until the per-process encoder is warm.
- 171 hosted-CI tests
- Fixed-2-CPU A/B lifted successful throughput from 20.7 to 100.1 req/s and cut p95 latency from 9,239 ms to 665 ms across ten alternating trials
- Kubernetes and Terraform exercised locally with kind and LocalStack — not claimed as a cloud deployment

Portcullis
A resilient MCP gateway with content-bound admission enforcement.
The Go data plane handles protocol validation, legacy translation, safe retries, circuit breaking, bulkheads, backpressure, multi-tenant policy, SSE streaming, failover, metrics and tracing. Its admission gate reads content-hashed verdicts from PostgreSQL before routing; an out-of-band Python worker scans newly discovered tool descriptions, keeping a multi-second classifier off the request path.
- Native path added p50 +0.80 ms in the documented local benchmark
- Circuit breaker opened and recovered in 6 seconds around a real upstream stop/restart
- An audit found the earlier scanner headline depended on near-duplicate family leakage; the split was rebuilt around held-out families and runs are now fingerprinted

FitForge
A product with concurrency-safe auth and a typed API boundary.
A React/TypeScript client builds and tracks workout plans through a FastAPI/PostgreSQL backend. Refresh-token redemption is a single conditional database update, so concurrent tabs produce exactly one winner; zod validates responses at runtime and CI checks those schemas against the backend's generated OpenAPI contract. Plan generation retrieves from a ten-document knowledge base with BM25 and vector search fused by RRF.
- Five green CI jobs on the current commit
- 113 backend tests including real-PostgreSQL integration and eight-thread refresh redemption
- 25 component tests · 17 browser tests
