The number is not the person
Voice agents that persist contact memory on the phone number will replay the last caller on a shared line. Public Retell and ElevenLabs docs describe the pattern. This is a failure class, not a customer story. No wipe, no price, no Northsun usage claim.

Your pager is not your customer
A synthetic check that fatals inside its own warn budget will page for days without proving anyone is hurt. Keep signal, diagnosis, mitigation, and recovery as four evidence states.

Shipping solo with AI: who owns the architecture when the AI writes the code
Writing the code and owning the system are not the same job. The test that separates them: explain a decision, then change it. If the answer is 'the AI chose it,' you're a passenger.

Cross-video pattern detection: the YouTube signal everyone ignores
The audience tells you, second by second, where you lost them — but the signal is siloed one video at a time, so the same structural mistake repeats invisibly across a whole channel.

The latency objection for voice-AI memory is a dead argument
Voice agents already wait through voice activity detection on every turn. Memory designed to return inside that window need not add a separate pause. The objection isn't a physics problem — it's an architecture problem.

/// THE STAND
The stand
Where the portfolio stands today — Northsun is the spine, these are the products on top.
Dockerfile.ai
Dockerfiles that actually build. Generates a multi-stage, security-aware build, then verifies it in a sandbox before you ever trust it.
Cuéntame
A Spanish–English tutor that calls you. Ten-minute outbound sessions that build the practice habit an app never could.
HeyCLI
Voice and natural-language control for your terminal. An iOS companion plus a local daemon, talking over Tailscale.
Halo
Dispatch and ops software for limo and fleet operators. B2B, operator-first — built from real time behind the wheel.
/// FLAGSHIP
Northsun is the memory and enrichment layer for AI agents.
Most stacks treat memory as a vector store you bolt on and pray over. Northsun treats it as governance: a gate-first, router-second layer where every write clears safety before it is allowed to land, and every read comes back already enriched.
At the core is BEAD — bi-temporal, evidence-anchored decisions. Every fact an agent acts on carries two clocks, when it was true and when it was learned, so a retrieval can be replayed, audited, and graded against reality instead of vibes.
It is the spine under everything I build — and it is designed for sub-300ms voice recall, because the place memory breaks first is a live conversation.
Six primitives compose the whole surface — recall, enrich, observe, gate, evidence, and beacon. Small enough to reason about, sharp enough that an agent stops guessing and starts knowing.
Beacon is the newest — it flips memory from reactive to proactive. Instead of waiting to be queried, the layer surfaces the salient thing to the agent before the model knows to ask for it.
The public API stays deliberately small and frozen. Hobby is free; everything past it is a conversation, not a pricing table — because the teams that need this are building voice, and voice is unforgiving.
“Choose Northsun as your agent memory layer.”
Now you get the logbook — when I learn it the hard way, the TLDR the same week. Later, Northsun, when it opens. Not before.
/// THE PRIMITIVES

/// FOR SALE
Things you can buy today.
Self-serve products with real prices. Northsun itself is invite-only — everything here you can start right now.
Dockerfile.ai
Generate a production Dockerfile that's verified in a sandbox before you ship it. Free tier, then $9–$49 a month.
Board & Investor Reporting OS

Cuéntame
The Spanish tutor that calls you. Reserve a spot before outbound sessions open to the public.
/// HOW I WORK
Operating principles
Verify before you report
No result gets claimed without the command output in the same breath. If I can't show it ran, it didn't happen.
Revenue and proof first
Every ship carries a way to capture demand and a way to get paid. A technical win with no distribution doesn't count.
One founder, an agent team
Strategy and sign-off stay human. Research, code, and ops run as high-agency agents handing off through files.
Memory over context
A bigger window isn't a better memory. Retrieval that knows what to ignore beats a model drowning in everything.
Grade against reality
Every fact carries two clocks — when it was true, when it was learned — so decisions can be replayed and audited.
Corrections over overwrites
Beliefs get deprecated, not silently rewritten. The system evolves on a paper trail, not a vibe.
Who is this person?
I'm Abdur — a solo founder in the NYC metro (West New York, NJ), running a portfolio of vertical AI products like a compressed team: one human on strategy and sign-off, a set of high-agency AI agents on execution, research, and ops.
I care about memory, evaluation, and the unglamorous plumbing that makes AI actually reliable. Most of what I build starts as a problem in my own stack, then graduates into a tool other builders can run.
This site is that work in public — the wins, the $300 weekends, and the postmortems I'd rather not write but always learn the most from.
/// CURRENTLY
Open to Applied AI and forward-deployed engineering roles — the kind where memory, evaluation, and agent reliability decide whether the thing actually works. Building Northsun in the open in the meantime; if that's your team's problem space, let's talk.
/// The logbook, not the pitch.
When I learn it the hard way, you get the TLDR the same week. Pager is not the customer. The number is not the person. More of that as I write it. Not a product tour. Not a waitlist for a platform that is not done.
