About
Product-minded full stack engineering
I connect frontend experience, backend reliability, and AI-powered automation in products built for real operations.
- Full stack engineer focused on practical, scalable software—frontend experience, reliable backends, and AI-powered automation working together.
- Strong fit for products where real-time communication, API integrations, and intelligent workflows define the user experience.
- Recent work spans AI chatbots, agent workflow platforms, streaming architectures, and multi-service integrations for real business operations.
- Care about maintainable systems, shipping useful products, and growing both technical depth and product judgment.
- Take features to production with Docker, nginx, CI/CD, AWS, and GCP—deployment and operations alongside application code.
Core skills
How I ship product-grade software
Focused capabilities I bring to full stack and AI product teams—balanced toward delivery, integrations, and maintainability.
Full Stack Development
I build cohesive product surfaces end to end—from interactive UIs to the services and data that power them—so features stay aligned with user and business goals.
Backend API Development
I design and implement APIs and service boundaries that stay predictable under load, integrate cleanly with clients, and remain straightforward to extend—primarily in Node.js, with Python where the stack calls for it.
Real-Time Systems
I work with streaming patterns, event-driven flows, and low-latency UX so live updates and AI-assisted experiences feel responsive and dependable.
AI / LLM Integration
I connect large language models and agent workflows into production contexts, with attention to prompts, tooling, safety boundaries, and operational behavior.
Database & System Design
I model data for clarity and performance, align schema with product features, and keep persistence layers understandable as products evolve.
Third-Party Integrations
I wire external APIs, webhooks, and platform-specific interfaces into stable product flows, with clear error handling and maintainable integration code.
DevOps & cloud delivery
I containerize and ship services with Docker, front traffic with nginx where appropriate, automate builds and releases through CI/CD, and deploy to AWS or GCP so environments stay repeatable and easier to operate.
