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.

Structured path through Python internals, typing, concurrency, data structures and algorithms.
Shipped OrderFlow: multi-tenant order management with enforced tenant isolation.
Building site-auditor: concurrent crawler with bounded, rate-limited async I/O under mypy --strict.
Typed by default — Protocols at the interfaces, strict mypy across everything new.

OpenTelemetry · Litestar · Strawberry GraphQL · KubeEdge Ianvs
Four pull requests merged into three widely used Python projects, reviewed by core maintainers.
OpenTelemetry: closed a silent TLS verification bypass in the Prometheus remote-write exporter, where the safe-looking setting turned certificate checks off.
Litestar: corrected HTTP semantics for multipart part-limit violations — 413 in place of 400, with regression tests and a breaking-change note.
Strawberry GraphQL: corrected PEP 681 dataclass_transform metadata so static type-checker behaviour matches runtime.
Two further fixes in review upstream on KubeEdge Ianvs, a CNCF edge-AI benchmarking framework.

Team Return-Path · problem statement SIH26106
Led six engineers building Postmark, an email threat detection and forensic intelligence platform.
Owned the backend: FastAPI service, PostgreSQL schema and access layer.
Set the test suite and branch-and-review workflow the team shipped against.

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.

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 · In progress
Systems and concurrency
asyncio in anger: bounded concurrency, rate limiting, retries with jitter and timeouts, behind Protocol-defined interfaces. Shipping in site-auditor and in the FastAPI service behind Postmark.
04 · Planned
ML systems
Serving, evaluation, data pipelines and the infrastructure models actually run on — the backend problem, with a harder correctness story. Started from the infrastructure side: upstream work on a CNCF edge-AI benchmarking framework.
