• Build infrastructure that lets an agent hold work beyond a single chat session: persistent memory, machines, accounts, communications, payments.
• Ship production backend services: typed contracts at the boundaries, deterministic cores, migrations that roll back in one revision.

• Refactored production Dagster pipelines from ad-hoc Supabase/SQL scripts into typed SQLModel DAOs, pure transformation layers, and an orchestrator, removing pandas outright.
• Replaced manual schema management with an Alembic/SQLAlchemy migration system — baseline revisions, whitelists, schema-diff tooling, autogenerate gating.
• Replaced mock-based tests with an ephemeral Alembic-stamped Postgres harness, ending silent ORM/DB drift.

• Translated cognitive-neuroscience research into shipped browser, mobile, AR, and VR applications: specifications, experiment design, and delivery with the engineers.

• Built detection algorithms over physiological, text and speech, and facial and gestural signals, turning raw behavioral data into features, metrics, and visualizations of emotional and cognitive state.
• Prototyped a VR stress-regulation game and a Bluetooth breathing and heart-rate monitor used in research workflows.

• Designed and ran behavioral experiments on multi-alternative choice: attraction, compromise, and dominance effects.
• Designed a habituation experiment with Dr. Colin Camerer on how repeated exposure alters valuation and choice.

• Run a production reading, notes, and AI workspace at nexus.nielseriknandal.com: EPUB, PDF, web, YouTube, and podcast ingestion, with an Android shell and a Manifest V3 capture extension.
• Rebuilt the ten-day FastAPI prototype from an empty repository into the production system — a Next.js BFF over FastAPI, SSE authenticated by 60-second single-use JWTs, background work on a Postgres job queue in place of Celery and Redis.
• Anchor highlights as Unicode codepoint ranges into canonical text; when client and server canonicalization disagree, the reader refuses to highlight rather than store a bad anchor.
• Shipped 1,571 commits and 211 Alembic migrations between December 2025 and August 2026, directing Claude agents that carry co-author trailers on 562 of them.

• Built LLM agents that turn free-text factory descriptions into typed configs for a deterministic EDD job-shop scheduler.
• Validated model output in one function: OpenAI JSON mode parsed into Pydantic schemas.
• Scored every parse against machine and job IDs regex-extracted from the source text.
• Wrote 419 backend tests; the suite mocks the model boundary and needs no API key.
