I'm a backend software engineer specializing in scalable, high-performance server-side systems — modernizing legacy architecture, building ERP/CRM integrations, and tuning APIs that perform in production.
Production APIs that stay fast as the data grows.

Migrated the retailer backend from Rails to Laravel and Go, helping cut API latency from 500ms & 3s to ~90ms via OpenSearch and Go. Built an Odoo integration syncing orders, inventory, and deliveries in real time with merchants' ERP systems. Redesigned the order lifecycle across enterprise and marketplace flows, and diagnosed a race condition in the async payment pipeline that was causing duplicate charges in production.
Shipped an Odoo-based laboratory platform into two production medical labs, architected a voice-assessment backend on LiveKit/OpenAI/Deepgram, engineered GPT + Stripe + Gmail outreach services at 100+ daily workflows, and built a distributed idempotent wallet engine settling transactions via RabbitMQ with a SHA-256 audit ledger.
Two roles, one throughline — backends that hold up in production.
Read the full résumé →A few things I've shipped — from ERP sync and clinical platforms to event-driven payments. The hard parts:
Odoo integration synchronizing orders, inventory, and deliveries in real time with merchants' ERP systems — plus an order lifecycle split cleanly between enterprise and marketplace flows.
Odoo-based clinical platform managing test ordering, sample tracking, and automated results reporting — successfully deployed across two production medical laboratories.
Backend for automated sales training and candidate evaluation via simulated voice calls — LiveKit/WebRTC streaming with OpenAI and Deepgram for real-time transcription and scoring.
Event-driven digital wallet settling transactions asynchronously across decoupled services via RabbitMQ, enforcing strict idempotency and pessimistic row locking, supported by a tamper-evident SHA-256 audit ledger.
Core backend services for an automated email outreach product, integrating GPT-driven content generation, Stripe billing, and the Gmail API to process 100+ daily email workflows reliably.
A queue-based Laravel/Filament CRM for high-volume lead management and bulk campaign delivery, plus LLM-powered tooling that automates backend scaffolding, REST route creation, and boilerplate generation.
Read the code, map the flows, find what actually breaks. No guesses.
Schema, contracts, and failure modes — written down before any code.
Small, reviewable changes. Tests where they earn their keep.
Migrations, observability, and rollback plans — not surprises.
Watch it in production, tune it, and hand it off clearly.
Tell me what you're building and I'll tell you how I'd approach it — the architecture, the trade-offs, and a realistic timeline. No homework, no NDA required.
You talk to the engineer who'll do the work — never a recruiter reading a script.
