Backend engineer focused on system design, multi-tenant architectures, and writing code that stays readable when the project grows. CS student by day, building production-grade systems by night.

/ About
The unglamorous stuff: clear boundaries, predictable data flow, code that reads like prose.
Salon Management SaaS — multi-tenant booking, scheduling, billing.
NextRush framework internals — middleware pipeline v2.
Distributed systems, consensus protocols, and event sourcing patterns.
Short-form notes on backend patterns over on Medium.
/ R&D
Framework sketches, design probes, and learning projects — the same engineering rigor, different shipping bar than client work. Each has a public case study.
A learning-driven Node.js framework — middleware pipeline, trie-based router, plugin system, and zero-dependency core. Built to understand how frameworks actually work.
An experimental JVM framework inspired by Javalin — simple routing DSL, no annotations, minimal surface area. A sandbox for understanding JVM web framework design.
/ Focus Areas
Six areas where most of my engineering hours go — mostly backend, mostly about keeping systems readable and predictable.
Shared-database tenant isolation using tenant_id scoping, permissioned queries, and clear domain boundaries.
Booking and time-slot logic where two users shouldn't be able to grab the same thing. Queues, locks, retries.
PostgreSQL schema and indexing decisions, migrations that don't scare me, and sensible caching patterns.
Service/repository separation, dependency inversion, and modules a teammate can navigate without a map.
Practical AWS setups — EC2, RDS, S3, load balancers — and the small amount of DevOps a small team actually needs.
LLM-driven workflows and small agent experiments, usually focused on developer tooling rather than chatbots.
/ Experience
A short track record — mostly backend, mentoring, and shipping production systems.

Notes on system design, backend architecture, and the small engineering lessons I collect along the way.
You’ve written @Injectable() dozens of times. But if someone asked you what it actually does, could you explain it without saying "it enables dependency injection"? I used to treat NestJS like a magic box. Write a...
I’ve seen this happen more times than I can count. A React app starts clean — components are small, state is local, everyone understands the code. Six months later, the same codebase is a maze. Components import from...
