Professional Summary
Backend-focused developer with 4 years of commercial experience building and supporting
internal business systems in PHP/Laravel. Core strengths are partner and third-party API
integrations, webhook and server-event processing, large-scale data processing, and
diagnosing problems in live integrations and services. Comfortable working inside an existing

experience is with Vue.js; additional production experience with Python/FastAPI and daily use of
AI-assisted development tools.

Work Experience
Fullstack Developer (PHP/Laravel, Python/FastAPI) — Remote
Renex NY Corp., USA — October 2022 – October 2026

Worked in a small internal product team of an e-commerce business operating in the Amazon
ecosystem. Developed and supported internal systems for inventory management, warehouse
operations, catalog processing, order synchronization and analytics.
- Integrated internal systems with partner and third-party APIs: Amazon SP-API, ShipHero
API, FedEx API, Keepa API, Infiplex API, and vendor FTP/SFTP sources.
- Processed inbound webhooks and server-side events: verified HMAC signatures against
the raw request body and made processing idempotent through a unique index on the
message ID, so retried or duplicated deliveries were never handled twice.

- Diagnosed problems in API integrations and services: analyzed request and response
payloads, read server logs, reproduced failures and traced them to the root cause
instead of the symptom.
- Handled external API rate limits with batch-based synchronization strategies.
- Worked with large datasets: catalog processing across 8 vendors and up to 1.6M
product records; optimized bulk writes using batch insert/upsert.
- Used Redis for caching, and Laravel Jobs, Horizon and Laravel Scheduler for
asynchronous and scheduled workflows.
- Created Docker-based development environments used by teammates, configured
Nginx, and connected to servers over SSH for diagnostics; worked with a DevOps
engineer on production deployment.
- Built Vue.js interfaces on top of the backend: admin pages, tables with filters, and
dashboards.
- Communicated with managers and the CEO to clarify requirements, propose technical
solutions and demonstrate completed functionality.
- Participated in requirements analysis, code reviews, hiring and onboarding.
- Used Claude Code daily: delegated routine tasks, split larger ones into small reviewable
steps, reviewed every diff and took responsibility for merged code.
