Founder, Databaaba · Amazon SP-API & Ads API
I'm Shahzeb Khan. I build software on Amazon's APIs.
I founded Databaaba, a one-person studio building custom software for Amazon sellers, vendors, and the agencies that run their ads: SP-API and Advertising API integrations, Marketing Stream pipelines, BigQuery warehouses, dashboards, and PPC automation. I write every line of the code myself, and I write up what I learn so other builders don't lose the days I did.
What I work on
Amazon data, pipelines, and automation.
Most of my work lives in one of these areas. If your problem sounds like one of them, we'll get along.
Amazon Marketing Stream
Hourly ad data pushed into your own AWS: the V1 Firehose and SQS pipelines I've run for clients, the V2 Parquet-in-S3 version that replaces them, and the warehousing and automation on top.
SP-API & Ads API
Orders, inventory, finances, restricted PII, campaign management, and the API access and app approval that come first. Multi-account and multi-marketplace.
Warehouses & dashboards
S3 → BigQuery pipelines, Looker Studio and custom dashboards, and reconciliation that shows why a number doesn't match Seller Central.
What I've built
Work that's running in production.
Each of these has a write-up with what was built, what broke, and how it was fixed.
Hourly dayparting control room
For a PPC manager running many client accounts: hourly budgets and rules with guardrails and logs, replacing third-party tooling that was too expensive at scale.
Vendor reporting for Alclear (Germany)
Marketing Stream in AWS plus Vendor Retail Analytics pulled through SP-API into BigQuery, unified in Looker Studio for the PPC team.
Data-integrity watchdogs
A five-layer integrity system with a nightly invariant watchdog for a multi-account marketplace platform, because a sync that silently stops looks exactly like a quiet sales day.
PII access and Amazon Custom orders
PII-safe order workflows and faster Amazon Custom order handling for moomentsDE, with fewer manual steps and fewer mistakes.
"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."
How I work
One developer, a fixed price, and code you own.
- You talk to the person writing the code. There's no account manager and no hand-off to a junior.
- A fixed quote before any work starts. If the scope changes, the price is agreed again before the work is done.
- You own everything. The code lives in your repository and the data in your own AWS or Google Cloud account.
- Small ways in. A $50 API access session, one-week $500 sprints for Amazon's deadlines, and scoped projects from $1,000. Pricing.
How I write
From real builds, not the docs.
Every guide on this site comes from a client build: the exact error string, the dead end, and the code that worked. Amazon changes its APIs often, so when it does, I update the post, link Amazon's own documentation, and date the change rather than quietly rewriting it. Editorial policy.
Find me elsewhere
I share builds in public.
I publish step-by-step walkthroughs on YouTube and write them up here on the blog. Follow along or reach out directly.
