About

Full-Stack Engineer with 5+ years delivering and maintaining production web applications across marketplaces, CRM, fi nance, HR, e-commerce, and SaaS. My core strength is backend and integrations: secure REST/GraphQL APIs, relational data models, role-based permissions, validation, third-party APIs and webhooks, and dependable business work fl ows with transactions and background jobs. I also build responsive React/Next.js and Vue interfaces from design mockups, so I can take a feature from requirements to a complete, tested user journey. Strong in TypeScript, Node.js/NestJS, Next.js, PostgreSQL/MySQL, and Redis, with Python (FastAPI) API experience. I care about tests, careful database migrations, logging and monitoring, clear documentation, and disciplined code review, and I adapt quickly to new domains and stacks.

Experience

Full-Stack Software Engineer

NOBS Marketplace · Remote

2025-05 – Present

Owned the end-to-end rebuild of the marketplace platform, from requirements and data modeling to APIs, frontend, and production deployment (Laravel, Vue 3, Inertia.js, MySQL, Redis). Designed a new relational schema and planned the migration of production data from a legacy unstructured system; tuned indexes and complex queries for large datasets. Built order work fl ows and lifecycle management with database transactions, validation, and role-based authorization so order state stays consistent under concurrent requests. Delivered advanced search/ fi ltering and client–provider messaging with secure, permission-checked APIs and responsive Vue interfaces. Moved high-volume work to Redis-backed background queues (Horizon) with retries, improving reliability and response times. Investigated production failures with logs and monitoring, found root causes, and shipped fi xes for database performance and reliability. Used Claude Code, Cursor, Codex, and Copilot for implementation and refactoring, reviewing and testing all AI- generated code before merging.

Software Engineer

Doplac CRM

2023-06 – 2025-05

Designed and owned backend modules and REST APIs for CRM automation and business work fl ows. Integrated third-party APIs and webhooks with asynchronous, failure-tolerant work fl ows (retries, idempotent handling) so external failures did not break business processes. Built queue-based processing and data pipelines handling millions of records using Redis and Horizon.
