Full-stack Software Engineer

B2B SaaS credit-management platform used by financial institutions and credit-focused businesses. Day-to-day backend in PHP/CodeIgniter 4 and MySQL, also working across web and mobile.

• Backend in PHP and CodeIgniter 4: REST APIs, business logic for credit workflows and integrations with third-party financial services.
• MySQL in production: schema design, indexing strategies, EXPLAIN-driven query optimization, and migrations on live tables without downtime.
• Async queues for long-running credit workflows, batch operations and external integrations — with retries, idempotency and dead-letter handling.
• REST API design: authentication (JWT/OAuth), role-based permissions, versioning, webhooks.
• Built a self-service loan onboarding flow from UX prototype to production (React, Next.js, TypeScript).
• Frontend architecture for credit workflows: schema-driven forms and module boundaries that isolate client-specific customizations from the core.
• React Native cross-platform mobile apps for iOS and Android, sharing types and validation contracts with the web.
• Integrated GitLab CI with Claude Code (Anthropic) to automate first-pass code review on PRs.
