Experience

Technical Lead

Automation Solutionz / Remote, Canada

Mar 2023 - present

  • Cut down costs by engineering a scalable test deployment architecture, achieving 93% CPU reduction and 4000+ daily deployments per client through Redis-based distributed queuing.
  • Architected and launched ZeuZ's AI-powered Codebase Analyzer microservice that turns repository analysis and artifact scanning into automated, human-reviewed implementation, orchestrating multiple LLM backends (Claude Agent SDK, OpenAI Codex SDK, OpenCode) behind a single service.
  • Leading ZeuZ Test Studio, a ground-up agentic testing platform — carried it from ideation through architecture to a complete interactive prototype — while helping drive ZeuZ's shift to full self-serve SaaS with public signup.
  • Built agentic development workflows with worktree isolation, human-in-the-loop feedback, diff/commit review, PR creation, and persona-based AI review, then productionized them with Docker/GHCR CI builds, SQL migrations, structured logging, and OpenTelemetry tracing.
  • Spearheading the idea, planning, and team-led development of an S3-compatible object storage migration away from single-host disk storage, guiding the move toward shared uploads and preparing ZeuZ for horizontal scaling and multi-machine deployments.
  • Implemented secure authentication system using PASETO tokens, fixing 33 vulnerabilities with 10x-30x performance improvement.

Software Engineer

Automation Solutionz / Remote, Canada

Sept 2020 - Mar 2023

  • Transformed monolithic system into microservices architecture and reduced deployment times by 75% (from 2-4h installs/upgrades to 10m) through Docker containerization and parallel deployment strategies.
  • Engineered real-time performance monitoring using BigQuery and Looker Studio for a major telecom client.
  • Implemented the platform's first authentication layer and real-time log streaming system using Rust/WebSocket.

Jr. Software Engineer (part time)

Automation Solutionz / Remote, Canada

Jan 2017 - Sept 2020

  • Reduced frontend load size by 78% and cut report/log processing time by 90% (from 8 hours to 45 minutes) for 500+ test cases through resource optimization and batch processing.
  • Upgraded Django from 1.8.2 to 3.1, resolving 100+ vulnerabilities in one day.

Projects

Ninetynine Systems

Rust, Kotlin, TypeScript, React Native

ninetynine.systems

  • Building a four-product indie suite near-solo with AI agents doing most of the implementation — including Orvia, an AI-native Android launcher with durable multi-turn agent runs, tool-use consent, multi-provider LLM routing, and append-only event-log storage.
  • Built Gatekeeper, a human-approval gateway for AI agents — Rust REST API and CLI, tamper-evident hash-chained ledger, durable outbox with webhooks/SSE/email, React approval inbox, and Expo mobile companion.
  • Built Billhead, a mobile-first invoicing SaaS (TypeScript monorepo, separate product/admin control planes, Stripe, API-enforced entitlements), and Planner, a local-first cross-platform weekly planner.

BitCode

Go, LLM Providers, Agent Tools, Terminal UI

github/bitcode

  • Built a Go agentic coding CLI similar to Codex/Claude Code — TUI and single-shot modes, multi-provider LLM backends, file/shell/web tools, subagents, resumable conversations, context compaction, and LLM-backed tool guards.

Redis-compatible Server

Rust, mio, RESP, AOF

github/redis

  • Built a Redis-compatible server from scratch in Rust — single-threaded mio event loop, RESP2 parser/encoder, command pipelining, lazy/active TTL expiry, memory accounting, AOF append/replay, and maxmemory eviction policies including Sieve.

Lorust

Rust, Tokio, RustPython, TOML

github/lorust

  • Built a Rust/Tokio HTTP load tester with rate/duration modes, TOML/RustPython flows, latency/error thresholds, structured metrics, and distributed worker/supervisor groundwork.

AIUBian

Java, Kotlin, Jsoup, Android SDK

github/aiub-app

  • Shipped an Android app for the AIUB student portal (notices, portal notifications, academic calendars) to 1k+ installs with a consistent user base.
