48-hour startup MVPs
Production App Router setups, auth, API routes, and CI/CD. We ship repos, not mockups.
Fractional engineering
Senior builds for teams that cannot wait on a six-month hire
For founders and product leads who cannot wait six months on a hire. We join your sprint with production Next.js, Python orchestration, and LLM pipelines.
Core stack
Production systems we ship on fractional sprints — from MVP auth and CI through agent fabrics, not slide decks.
Application & APIs
Next.js 15 (App Router, RSC) · React 19 · TypeScript · Server Actions & Route Handlers · Python (FastAPI, Pydantic v2) · Zod
Data & persistence
PostgreSQL · pgvector · Supabase · Redis · Stripe billing hooks · migration-safe schemas
AI, agents & eval
RAG & retrieval pipelines · tool-use agents · eval harnesses & regression suites · hosted & local LLM routing · cost-aware model selection · MAPOS-style deterministic orchestration
Cloud, platform & delivery
AWS · Azure · VPC & private endpoints · Docker · Vercel · GitHub Actions · IAM landing zones · secrets & env validation
Observability, quality & compliance
OpenTelemetry · structured audit logs · Vitest & pytest · human-in-the-loop release gates · SOC-aligned data handling patterns
Deterministic Multi-Agent Fabrics
RAG pipelines, tool-use agents, eval harnesses, and routing across open and local models.
Fractional CTO
Architecture reviews, code evaluation, hiring loop help, and hands-on code when the sprint is blocked.
Cloud & compliance
AWS and Azure landing zones, IAM boundaries, and audit-friendly logging for regulated domains.
