Available for senior Rust & platform roles

I build production Rust systems
that scale under real load.

Founding Engineer · Rust, Axum, Tokio · Distributed Systems & AI Infra

I took a multi-tenant warehouse platform from zero to production — 10K+ daily transactions across 5+ facilities. Migrated hot paths to Rust, cut P99 latency 800ms → 120ms, and shipped agentic AI workflows that reduced manual ops by ~70%. I own architecture, code, and releases end to end.

Rust-first engineering

What CEOs and CTOs get when they hire me — not slides, shipped systems.

🦀 I write Rust for money, not for tutorials.

Production Axum services, concurrent inventory locking, PostgreSQL RLS multi-tenancy, Redis-backed async pipelines, OpenTelemetry in prod, and AWS EKS releases. I migrated the paths that hurt — and measured the win.

CodeApto India
Founding Engineer · Full Stack / Rust Backend
Aug 2023 – Present · Bengaluru
  • Architected multi-tenant WMS backend (Rust/Axum/Tokio) — 10K+ daily transactions, 5+ facilities, PostgreSQL ledger with integrity guarantees.
  • Migrated performance-critical inventory paths from Node.js to Rust — eliminated race conditions, P99 800ms → 120ms under concurrent load.
  • Shipped LangGraph invoice agents with human-in-the-loop, Redis queues, FastAPI — ~70% less manual data entry.
  • Designed 40+ REST APIs: cursor pagination, idempotent writes, RFC 7807 errors, tenant RLS + RBAC on every path.
  • Built event-driven pipelines — 5K+ daily background jobs decoupled from API via Redis queues/pub-sub.
  • Owned AWS EKS releases (Docker, K8s, Terraform, CI/CD); deploy cycle 45 min → 8 min; OpenTelemetry tracing in production.

Freelance Full Stack / Backend Developer
Jan 2020 – Aug 2023 · Remote
  • Delivered 8+ startup products end to end — Node.js, React, MongoDB, auth, admin tools, 1K+ DAU.
  • Defined API contracts and schemas that kept frontend teams shipping on tight cycles.

Enterprise WMS (Multi-Tenant)

Full-stack warehouse platform — RBAC, event-driven inventory, WebSocket floor updates, AI-assisted data entry. Rust on hot paths.

Rust Axum PostgreSQL Redis AWS EKS

Inventory Locking Layer (Rust)

Rewrote stock reservation in Rust with transactional guarantees. Load-tested concurrent updates — the migration that fixed production races.

Why companies hire me

Built for founding-engineer and senior Rust roles at startups and scale-ups.
“Give me ambiguous product requirements and a production incident — I'll ship the design doc Monday and the Rust PR Friday.” — How I work as a founding engineer
🎯 0 → 1 ownership
First engineer on WMS — backend, agents, infra, releases. I don't wait for a spec; I write one and build it.
🦀 Rust where it counts
I don't rewrite everything in Rust. I profile, identify hot paths, migrate with metrics — 6.7× P99 improvement proved it.
📐 API & data discipline
40+ endpoints with idempotency, RLS, RFC 7807 — contracts that partners and frontend teams trust.
🤖 AI that ops trusts
Human-in-the-loop agents, not demo chatbots. ~70% automation with explicit review paths for production rollouts.
