An internet scale digital locker service. Originally built to be the preferred digital document locker for the Indian subcontinents' denizens through a government initiative. The goal was to be able to scale for a billion people and terabytes of data.

A microservices architecture in Python built atop Microsoft Azure's cloud allowed for this to be certified as scalable to the aforementioned level by Microsoft itself.

As the architect of the system I had a large hand in the infrastructure and code design philosophies, specifically targeted at scale and security, and as a developer I assisted in implementing the design.

A website uptime tracking service built to look through large sections of the internet and continuously track the uptime of websites.

Initially, this began with 80 million websites, which was reduced to a modest 3.6 million "valid" websites. Each of which was monitored every half hour for their uptime statistics and stored for later processing and statistical analysis.

I architected, implemented, and operated the entirety of the web scan engine.

This company already had an established codebase with a small business running on it. With minimal funding, they were ready to invest their capital in a system re-write as the current code base was badly written and had a host of issues plaguing them.

I was the technical lead on the project. As a team, we decided the investment capital was better spent on growing their customer base than re-writing the system. We fixed every bug we could find and completed "under the hood" refactors of the codebase to ensure the best standards were followed throughout their business layer.

We also introduced a rule-based throttling system to their email campaign engine to allow their marketing campaigns to remain in the "non-spam" category.

Following this, an entire line of business was introduced, around eCommerce, within the short span of four weeks. This allowed for a lean method of testing the given business and iterating without breaking the bank.

This was a crucial decision that helped them spend on their customer acquisition and retention, pushing them towards their first million in revenue. This was a pivotal point as now they are growing over 300% YoY. Their first million is but a blip in the past.
