About

I am a full-stack software engineer and team lead with hands-on experience building, scaling and managing production-grade software systems, with a strong focus on travel technology and OTA platforms.

I currently work on an online travel agency platform that handles more than 40,000 flight tickets a month. I am involved in the development and management of the complete production ecosystem: application architecture and development, infrastructure, databases, deployment, integrations, monitoring and optimisation.

Travel technology#

My experience includes building and integrating systems for:

• Flight search, pricing and booking
• Hotel booking
• eSIM
• Attractions
• Bus and train booking
• Payment and transaction systems
• Multiple third-party travel suppliers
• Booking and status webhooks
• Reporting and operational systems

Working with multiple suppliers has given me practical experience handling API timeouts, slow suppliers, failures, retries, availability changes, pricing differences, booking issues, concurrency and real-time status updates.

Production and infrastructure#

I take responsibility for the full production environment:

• Linux server management
• Nginx and PHP configuration
• Cloudflare, DNS and SSL
• Deployment and release management
• Redis and queue systems
• Cron jobs and scheduled processes
• Production troubleshooting
• Performance and reliability optimisation

I am comfortable troubleshooting problems across the entire stack, from application code and database queries to servers, networks and third-party APIs.

Development and database#

My core technologies are Laravel, PHP, Vue.js 3, Inertia.js, Next.js, MySQL, Redis and REST APIs. I work with complex business logic, large datasets, database optimisation, caching, queues, asynchronous processing, authentication, webhooks, API integrations and performance tuning.

Team leadership#

As a team lead I am involved in technical planning, architecture decisions, task distribution, code reviews, mentoring, production troubleshooting, supplier coordination and delivering features reliably.

What is next#

I am exploring AI, automation and SaaS products, focusing on practical solutions that automate business processes and create better products.

I enjoy taking ownership of the complete journey:

Architecture → Development → Database → Infrastructure → Deployment → Production → Optimization → Scale

Build. Solve. Optimize. Lead. Scale.
