Khalil B.

I’m a Lead Software Engineer with 5+ years of experience building, scaling, and maintaining production-grade SaaS, eCommerce, and web platforms. I specialize in turning complex business requirements into reliable, scalable software systems, from architecture and backend development to cloud infrastructure, integrations, observability, and AI-powered workflows. What I bring as a Lead Engineer Software architecture & technical leadership SaaS architecture and multi-system integrations Full-stack TypeScript development Backend engineering with Node.js / NestJS Frontend engineering with Vue.js / Nuxt Cloud & production systems with Google Cloud / AWS PostgreSQL, Redis, GraphQL & REST APIs Payments & third-party integrations (Stripe, Adyen, PayPal, Google Pay, Klarna, etc.) AI-powered applications, LLM integrations & automation n8n workflow automation Observability, monitoring & production debugging Performance, scalability and reliability I’m comfortable taking ownership of a project beyond simply writing code: understanding the business problem, choosing the right architecture, making technical trade-offs, implementing the solution, and keeping it reliable in production. Recent experience I've worked on production systems involving: SaaS platforms and subscription-based applications Headless eCommerce architectures with Magento + Vue/Nuxt Payment and checkout systems GraphQL and REST APIs Cloud-based applications and distributed services AI chatbots and AI-assisted business workflows Automated workflows using n8n Monitoring and observability with tools such as OpenTelemetry, Grafana and Sentry Large-scale frontend/backend integrations I also actively use AI coding and development tools to accelerate implementation, debugging, testing, and research while maintaining engineering ownership over architecture, security, code quality, and production reliability. How I work I don't just deliver tickets. I aim to become a technical owner of the product or system I'm working on. If you need someone who can move between architecture, backend, frontend, cloud infrastructure, integrations, and AI, while communicating clearly with stakeholders and taking responsibility for the final result, I can help.
