I build AI products that have to work outside the demo.
I help founders turn ambitious, incomplete AI ideas into working products—especially when the hard part crosses product decisions, software, and the real world.
8+ YEARS BUILDINGHARDWARE → VOICE → AGENTS → VERIFICATION
01 / HOW I GOT HERE
The projects were separate. The responsibility boundary kept returning.
This was not a planned sequence. Looking back, each project forced a different answer to what software could infer, what it could safely do, and what should count as evidence afterward.
01PHYSICAL SYSTEMS2019—24
The signal had to survive the real world.
Cerebralx / Xone put me inside electrodes, noisy EEG, firmware, embedded hardware, and the gap between a compelling demonstration and a dependable loop.
I learned to treat measurement, feedback, and failure as part of the product—not implementation detail.
02CONVERSATIONAL PRODUCTS2024—26
A conversation only matters if the product can use it.
PerPitch and perMail were independent products in different contexts. Both made timing, ambiguity, and the handoff after a conversation impossible to ignore.
I became less interested in a model sounding capable and more interested in the work the conversation could reliably complete.
03GOVERNED ACTION2026—NOW
An agent action needs an owner and an observable result.
Julie and CarbonCompute approached machine action from different directions: enterprise records in one, funded human work in the other.
Both reinforced the same boundary: interpretation can be probabilistic; authority, state, and settlement cannot be vague.
02 / SELECTED WORK
Five products. Five different boundaries between understanding and action.
Each chapter shows one recognizable product moment, what I owned, and the strongest public evidence the record supports.
01 / 05REAL-TIME VOICE PRODUCT
RECENT BUILD · 2026
perMail
A phone agent that knows when the call needs a human.
An AI receptionist that handles missed calls, identifies urgency, and turns the conversation into a clear owner handoff.
Ayush owned
Sole builder across voice, backend, and handoff.
Ownership evidenceFULL PATH · owned by AyushEvidence notes +
Voice loop, backend, handoff, alerts, and reliability debugging.
Customer identities, numbers, recordings, and caller data remain private.
Name what the model may infer, what the product already knows, and what must remain unresolved.
Interpretation boundary02
Who has authority?
Turn consequential behavior into narrow actions with explicit owners, permissions, and approval points.
Action boundary03
What proves completion?
Read back durable state, expose partial failure, and leave enough evidence to recover or reconcile.
Verification boundary
04 / WORKING WITH ME
Bring me the unclear, consequential part.
I work directly with founders and product leads when the brief is still moving and the product needs judgment across interface, model behavior, backend state, and delivery.
Expect short feedback loops, working software early, written decisions, and direct conversations about what the evidence does—or does not—support.
01
Frame the risky workflow
We identify the user moment, system boundary, and assumption most likely to invalidate the product before polishing the easy parts.
A decision map and a testable first slice02
Build the consequential path
I work across product and implementation to make the live call, model handoff, external write, or device loop real enough to judge.
Working software around the hardest path03
Make the outcome inspectable
We add approval, readback, audit state, and recovery where the product needs to earn trust rather than merely announce success.
A system the team can evaluate and continue
BEST FIT
Product and system audits · focused risky-slice builds · embedded 0→1 delivery
I’m extending applied product work into the technical foundations that can justify trust: task-based evaluation, constrained deployment, and stateful agency.
APPLIED DIRECTION
Agent evaluation
Testing whether an agent completed the real task—not whether its explanation sounded convincing.
APPLIED DIRECTION
Local intelligence
Smaller and on-device models where privacy, latency, cost, and hardware are product constraints.
LEARNING DIRECTION
World models
How agents maintain state, understand an environment, and connect reasoning to grounded action.
