Projects: 11 engineering case files by P S Sree Harsha

Mission Console

Production Systems & Case Files

8 engineering case studies across production AI, agentic systems, distributed backends and full-stack products, supported by cloud delivery and MLOps, plus the 3 earlier builds they grew out of. Each case connects the customer, problem, system design, scale and measurable impact.

Production systems05

Systems I architected and shipped, with the decisions, trade-offs and measured outcomes behind them.

Reason across systems, retain their boundaries

The proposal consumes published APIs without replacing systems of record.

Original architecture diagram

Every function runs its own tooling, dashboards and AI, so teams spend an estimated 60–70% of analytical effort assembling context before deciding anything. A major GPU procurement can move through six functions with every dashboard green and still land hardware before capacity is ready. The failure is not execution; it is that nothing reasons across the domain boundaries.

Original architecture diagram

Incident triage across multi-tenant log streams was manual and slow, with root-cause analysis bottlenecked on tribal knowledge and no safe way to handle sensitive data.

Choose the screening. Choose the seat.

Theatre and showtime filters define the screening before a seat is selected.

A quantity field hides the one thing a buyer actually cares about: which seats are still free. Booking is only useful when the map shows what is already taken.

Note-taking stops being useful the moment capture costs a page load. The composer has to stay one keystroke away and out of the way the rest of the time.
