Senior Software Engineer focused on building production-grade systems that actually scale. I work across full-stack web, cloud infrastructure, and applied AI—shipping things that don’t fall apart under real users.
- Design and build scalable distributed systems
- Ship AI-powered features (LLMs, embeddings, retrieval systems, automation)
- Own end-to-end architecture — from frontend to infra
- Optimize for performance, cost, and reliability, not just “it works”
- AI-native applications (not bolted-on features)
- Real-time systems and event-driven architectures
- Cloud infrastructure (AWS, containers, orchestration)
- Developer tooling and internal platforms
Frontend
- React, Next.js, React Native (Expo)
- Tailwind, Styled Components
- State management (Redux, Context API)
Backend
- Node.js, Express
- REST, GraphQL
- PostgreSQL, MongoDB, Firestore
AI / Data
- OpenAI APIs, embeddings, RAG pipelines
- Prompt systems that don’t break in prod
- Data pipelines + transformation
Infra
- AWS (ECS, S3, EC2)
- Docker
- CI/CD pipelines
- Systems > features
- Latency matters
- If it can fail, it will — design for it
- Simplicity scales, cleverness doesn’t
- Measure everything, guess nothing
- Built AI-driven applications integrating LLM workflows into real products
- Designed scalable backend systems handling real-world traffic
- Developed integration platforms (APIs + testing + docs in one place)
- Worked across full-stack projects with production ownership
Working on something that needs to scale, handle real traffic, or actually use AI beyond demos? I’m interested.
- Open to collaborating on AI-first products, infra-heavy systems, and complex backend architectures
- Available for contract work, consulting, or full-time roles
