I'm Shahzeb, leading a lean studio focused on Amazon data, dashboards, and automation. From Marketing Stream to SP-API integrations, quietly hands-on, always shipping.
Selected work
A few builds you can go look at — from a full agency app to multi-channel sync and marketplace PII tooling.
Built a full-fledged app for Kiloverse — data pipelines through to the dashboards their team runs on every day.

Read the walkthroughIn their words
Minti runs Amazon for multiple large brands at Kiloverse across the US and EU marketplaces. Third-party dayparting tools couldn't express the strategies his team actually wanted to run — so we built the thing that could.
"We were lacking functionality with third-party tools to apply our strategies. You really helped us implement our real strategies and improve the ROAS, ACoS, profitability and revenues. It was a great achievement for our team."
"I'm going to be honest — I wasn't expecting much at first. But what you've done really exceeded my expectations. You delivered more than I was really asking for."
Minti
Head of Amazon BD, Kiloverse
Recorded after the first working version shipped. The build has since grown into the app their team uses day to day — adsilio.com.

Guides
Step-by-step guides on Amazon SP-API, the Ads API, and Marketing Stream — written from real builds.
Amazon Ads API
7 min readA 429 storm from the Amazon Ads API almost always means your retry logic is wrong, not that your limits are too low. Here's how the per-endpoint token buckets actually work, what the response headers tell you, and the request patterns that keep you comfortably under the limit.
Amazon SP-API
8 min readThe SP-API Reports API is asynchronous — request, poll, download, decompress — and most broken integrations either treat it like a synchronous call or poll it straight into a throttle. Here's the correct four-step flow, the status states that trip people up, and the gzip gotcha at the end.
Guides
7 min readI build custom Amazon PPC automation for a living and I still tell most people to buy the SaaS. Here's a straight comparison of custom builds versus tools like Pacvue and Perpetua — what each does better, the real cost math, and how to tell which side of the line you're actually on.
