●●SolidSolve My Problem
Cuts Lambda handler boilerplate in half, but Zappa and Chalice already exist.
Strengths
- •Dependency-free design keeps Lambda cold-start overhead minimal
- •One-line parameter extraction with validation (types, ranges, enums)
- •Automatic request ID and timestamp injection into consistent response format
Weaknesses
- •Solves a known problem in crowded serverless framework space
- •Limited to API Lambda patterns; no async, streaming, or event routing

Post Description
I built a small Python utility library for AWS Lambda.
Lambda handlers often grow not because of business logic, but because of repetitive I/O glue code:
- event parsing - parameter validation - type casting - response formatting - error handling
slat-io isolates that I/O layer so handlers can stay small and focused on business logic.
It's intentionally tiny, dependency-free, and not a framework.
Still early, but I'd love feedback on the approach and API design.

Deadcode Removal Layer for My Compiler in Less Than 140 LOC
This is a concise dead-code-elimination pass implemented as ~140 LOC of readable Rust: it walks op dependencies via a match over Op variants, collects reachable OpRefs, and prunes the op pool. It’s not reinventing compiler theory, but the implementation is tidy and immediately pluggable into a small IR/dataflow project — useful as a reference or drop-in optimizer. Lacking benchmarks, docs on integration, or tests, it’s more of a pragmatic utility than a research contribution.

AgentForge – Multi-LLM Orchestrator in 15KB
AgentForge packs provider adapters (Claude, GPT‑4, Gemini, Perplexity), token-aware rate limiting, retry/backoff, and a MockLLMClient for tests into a tiny dependency surface — the 15KB footprint and 2 dependencies is an attention-grabber. The 3‑tier Redis cache and benchmark claims (huge latency/memory wins vs LangChain, 88% cache hit) make it a tempting low-overhead alternative, though you should validate provider feature parity and benchmarks against your workload.
