ROHIT_KUMAR_ROY > BUILDING_RELIABLE_BACKENDS
Backend engineer. I prefer Go, but what I really care about is the structural decisions: where data lives, how services talk to each other, what fails silently versus what fails loud. Interning at Journalyst right now, working with real traders' data.

Performance discipline
Backend Core
- Microservices with clear service boundaries and domain ownership.
- gRPC and Protobuf interfaces with deterministic contracts.
- REST support where external integration calls for it.
Data and Runtime
- PostgreSQL and MySQL schema design tuned for query efficiency.
- Redis for low-latency state, cache layers, and pub/sub patterns.
- Concurrency-safe implementation patterns in Go.
Delivery and Quality
- Docker-based local and production parity.
- Linux-first deployment and debugging workflows.
- Prometheus metrics, testing, and benchmarking loops.

Zaraba
Designed as a gRPC-first architecture splitting API, trading core, and market/wallet services. Added fixed-point arithmetic to avoid floating-point drift in financial execution paths.
Thesis: deterministic execution over noisy realtime input.

Apr 2025 - May 2025
Multi-stage pipeline: source fetchers (ATS APIs, YC, Internshala, RSS, HN, Reddit) → normalized MD5 dedup → rule-based prefilter (cuts ~95% AI cost) → Groq LLM scorer → Telegram push. Built with Python, SQLite, and zero paid infra.
Thesis: filter ruthlessly before scoring expensively.

Sentinel-Proxy
Mar 2026
Uses a streaming inspection pipeline and Redis-backed behavior tracking with adaptive thresholds to reduce false positives while preserving detection sensitivity.
Thesis: observe behavior, not just packets.
