Experience

Engineering study and the manufacturing business ran in parallel rather than in sequence — teal marks the engineering track, ochre the operational one. The engineering track is where the next decade goes.

Managing Director
Agam Agrovet Private Limited · West Bengal, India
Accountable for production, quality standards, procurement and finance at an animal feed manufacturer.
Ran the constraint side of a physical system: batch tolerances, supplier reliability, working capital.
The transferable part is the ordering — failure modes and edge cases get designed for first, not patched later.

First contact with programming.

Where this goes

01 · Complete
Fundamentals
C, memory, data structures, algorithms. CS50x, then continued in C on my own.
02 · In progress
Backend in depth
APIs, data modelling, authentication, and typed service code. One stack understood properly rather than five sampled.
03 · Planned
Systems and concurrency
asyncio, queues, caching and the failure behaviour of distributed components. Formalised alongside the systems track at BITS.
04 · Planned
ML systems
Serving, evaluation, data pipelines and the infrastructure models actually run on — the backend problem, with a harder correctness story.
