About
HadayaLab is an engineering lab and sovereign holding company architected by Founder & Principal Engineer Hajime Chiba. Born from intense engineering battles against brittle multi-agent sprawl and API cost inflation, we build hardened, production-grade AI infrastructure. Our proven operations span enterprise Upwork catalog weaponization ($15k–$45k Turnkey OEM packages), top-tier RLHF alignment under contract LBLX116 ($200–$400/hr, 21 elite specializations), and zero-fixed-cost software rollups ($205k portfolio valuation, <$10/mo infra overhead). We reject toy RAG demos and unverified AI slop—every line is backed by AST-level verification and deterministic ground truth.

I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my favorites.
Official enterprise Upwork Project Catalog asset. Ingests omni-directional B2B leads, filters low-margin RFPs via Kinoshita Activity-Based Costing (ABC) invariants, and deploys high-converting PASONA direct-response proposals. Delivered as an isolated multi-tenant Docker/Next.js/FastAPI stack with 100% BYOK cost neutrality.
Production RLHF auto-adjudication pipeline engineered to overcome Labelbox UI paste barriers (insertFromPaste enforcement). Integrates Tampermonkey DOM observers, Chrome DevTools Protocol (CDP), and direct Gemini Vertex API ground-truth reasoning to classify multi-speaker speech transcripts with 79.4%+ precision.
Deterministic pre-tool interceptor and code verification gate. Parses Python AST syntax trees to eradicate silent fallbacks, empty try-except blocks, mock return fakes, and unhandled exception swallowing before code reaches production. Enforces zero-hallucination compliance across AI agents.
High-performance video and booking educational architecture built for AtsukoEnglish and family tutoring. Replaced $199/month recurring third-party SaaS subscriptions with Next.js 15, Cloudflare R2 video streaming, Cal.com open-source scheduling, and zero ongoing platform fees.
Engineering Sprints & Milestones
A timeline of high-leverage architectural milestones, acquisitions, and deep-tech alignment challenges solved across global infrastructure.
The Battle for Ermis (Phase 3 Alignment Trial)
San Francisco / Remote
Faced high-stakes assessment failure risks due to portal JavaScript obfuscation and model token limits. Deployed Gemini Flash solver (ermis_solver.py) in tandem with founder manual oversight, achieving an 87.1% verified pass rate across 149 production tasks to secure the master LBLX116 production baseline.
CQS Boundary & Governance Architecture Reform
HadayaLab HQ
Postmortem INCIDENT-20260906 resolution. Codified strict Command-Query Separation (CQS) invariants and BigQuery DWH-first atomicity, eradicating ad-hoc script drift and establishing deterministic multi-tier hound swarms.
Gemini 4 Argon & Rust Zero-Toil Platform Transition
Global
Upgraded enterprise infrastructure to Antigravity v2.19.1 and prepared systems for Gemini 4 Argon. Eradicated persona hallucination overhead and deprecated runtime layers across all sovereign repositories.
Enterprise Deal Qualification
Direct qualification terminal for OEM licensing ($15k–$45k), SaaS buyouts, and sovereign custom architecture. Instant calendar unlock for qualified buyers.
