Core expertise

AI depth. Commercial range.

Algorithms, product engineering, and direct experience operating Agent systems—applied wherever the problem lives.

01

Agent systems and AI-native delivery

Design Agent workflows that can investigate, use tools, produce artifacts, recover from ambiguity, and hand consequential decisions to a human expert.

  • Multi-agent workflows
  • Evaluation & guardrails
  • Human-in-the-loop
02

Algorithms and machine learning

An algorithm engineering foundation for reasoning about model behavior, learning systems, search spaces, and where automation will fail.

  • Reinforcement learning
  • Deep learning
  • Data & model reasoning
03

Product and platform engineering

Move from an open-ended idea to a working product, production change, or technical system with explicit architecture and verification.

  • AI-native products
  • Web & cloud systems
  • Automation
04

Cross-industry problem solving

Transfer the same technical method across unfamiliar domains: model the system, find the evidence, build the smallest useful solution, and verify it.

  • Commerce
  • Media
  • Operations

Delivery cases.

The 24/7 Agent handles the continuous work. When evidence conflicts or a live step becomes risky, the expert corrects the diagnosis, changes the plan, or stops the release.

01Shopify · Storefront

Storefront conversion, shipped safely

TimePreview in ~4 hours
Indicative price$100–$200
Problem

An older theme made in-stock products hard to find, but the merchant could not risk breaking the live catalog or checkout.

Traditional delivery

Multiple calls to explain a legacy theme, followed by development and QA against a live revenue path.

Our method · Agent + Expert

The 24/7 Agent. Built the duplicate theme, ran repeatable checks, and kept the launch moving as approvals arrived.

Human correction. A preview can look correct while inventory logic or checkout behavior still breaks after publish. Checks the intended behavior and launch evidence, then corrects the implementation or stops publish before revenue is exposed.

Buyer advantage. One async approval, a working preview in ~4 hours, and follow-through through launch and customer feedback.

02Jotform + Stripe

Payment recovery across systems

TimeFirst trace in ~3 hours
Indicative price$40–$100
Problem

Paid form submissions were visible, the money was not—and the replacement checkout was already working.

Traditional delivery

The form vendor and processor pass the case back and forth while the buyer searches accounts and repeats context.

Our method · Agent + Expert

The 24/7 Agent. Kept one PaymentIntent timeline, processed each vendor reply, and prepared the next exact ask.

Human correction. Similar IDs can be joined to the wrong account, or a historical recovery can be mistaken for a live checkout failure. Rechecks account ownership, separates the two payment paths, and redirects the escalation without exposing sensitive data.

Buyer advantage. First trace in ~3 hours, no repeated retelling, and continuous follow-up until the funds were found.

03Cloudflare + Kajabi

Infrastructure root-cause diagnosis

TimeInitial trace in minutes
Indicative price$40–$100
Problem

The www domain worked. The bare domain failed—but only on one Windows machine.

Traditional delivery

Reissue certificates, change DNS, clear caches, or book screen shares before proving the public infrastructure is broken.

Our method · Agent + Expert

The 24/7 Agent. Compared public and local evidence, read each returned test, and issued the next isolation step.

Human correction. Public symptoms can trigger unnecessary DNS or certificate changes when the real fault is local. Challenges the conflicting evidence, blocks speculative infrastructure changes, and switches the investigation to the machine.

Buyer advantage. Initial trace in minutes; async follow-up continued until two stale hosts entries were confirmed and removed.

04Mirakl + Billit + Make

Finance automation with guardrails

TimeProof in hours; staged rollout
Indicative price€600–€700
Problem

Marketplace orders, invoices, credits, Peppol status, and logs had to agree without duplicates in production.

Traditional delivery

A large upfront specification, separate build and UAT phases, and production evidence arriving near the end.

Our method · Agent + Expert

The 24/7 Agent. Mapped APIs, built and monitored scenarios, reconciled every run, and kept exceptions visible.

Human correction. A sandbox pass can still hide duplicates, wrong values, or an unsafe schedule or credential in production. Reviews reconciled counts at each live gate, stops the scenario on variance, and approves reactivation only after correction.

Buyer advantage. Proof arrived in hours; staged delivery controlled production risk through activation and post-launch monitoring.

05AI video · Brand creative

AI-assisted creative production

TimeFirst 4K cut in ~24 hours
Indicative price$60–$120
Problem

A brand lead considering a larger video program wanted one finished proof—not another reel or promise.

Traditional delivery

Brief, storyboard, edit, voice-over, and revision coordination across several creative handoffs before a usable first cut.

Our method · Agent + Expert

The 24/7 Agent. Generated and edited assets, incorporated notes, and ran frame, brand, and audio QA continuously.

Human correction. A technically clean render can still drift from the product, brand, narrative, or visual continuity. Reviews brand-critical frames and buyer feedback, then redirects prompts, edit choices, or the approval checkpoint.

Buyer advantage. One asset handoff and a concise approval loop produced the first 4K cut in ~24 hours with brand QA intact.

06Google Business Profile

Local presence recovery

TimePacket delivered same day
Indicative price€80–€150
Problem

A current operator was trapped between its hidden profile and a former business listing at the same address.

Traditional delivery

A monthly local-SEO retainer or repeated tickets where the owner retells the history and risks an unsafe profile merge.

Our method · Agent + Expert

The 24/7 Agent. Kept the full case history, watched Google replies and deadlines, and prepared each next response.

Human correction. Ambiguous profile states can lead to the wrong business being merged, reported, or stripped of reviews. Separates the entities, rejects unsafe merge tactics, and changes the evidence strategy before a harmful request is sent.

Buyer advantage. A same-day packet, no repeated retelling, and continuous follow-through until Google confirmed visibility.

07Merchant Center + Nuxt

Commerce data integrity

TimeDiagnosis in <1 hour
Indicative price$80–$150
Problem

Shoppers and developers saw the correct price; Merchant Center still called it missing.

Traditional delivery

A broad SEO audit or open-ended developer investigation that starts with more access and little fault isolation.

Our method · Agent + Expert

The 24/7 Agent. Compared page, schema, robots, APIs, and metadata in parallel and assembled a fault map.

Human correction. One noisy signal can be over-weighted, producing a broad audit or fix that misses the actual conflict. Weighs the conflicting signals, reranks the blockers, and narrows the recommendation to the smallest verifiable fix.

Buyer advantage. A precise diagnosis in under an hour replaced a broad audit with one developer-ready remediation order.

08Shopify App · Go-to-market

Early-stage product positioning

TimeBrief delivered same day
Indicative price$40–$100
Problem

A newly approved app had broad positioning, no reviews, and almost no response to daily outreach.

Traditional delivery

A positioning workshop and long research deck before one message reaches a real merchant.

Our method · Agent + Expert

The 24/7 Agent. Audited public assets and market signals, generated focused copy, and prepared a seven-day test.

Human correction. Generic category patterns can produce polished positioning that optimizes vanity metrics instead of first users. Rejects unsupported claims, resets the buyer wedge, and makes real merchant use—not activity—the proof threshold.

Buyer advantage. A same-day brief replaced workshops and a long deck with one focused, execution-ready buyer experiment.
