Senior full-stack engineer (6+ YOE) and B2B contractor specializing in designing and scaling cloud-based systems for startups and enterprises. I’ve led architecture and implementation for ML annotation platforms, booking engines, and internal enterprise tools, often owning delivery end-to-end while coordinating with product and backend/frontend teams.
Highlights:
- Built a real-time ML data annotation platform, doubling throughput for annotators while reducing SQL query loads by 100–1000x across critical services.
- Optimized Celery async pipelines, achieving 12x faster builds and improving system resiliency.
- Led development of a tour booking engine (React/Next/Django) from architecture to launch.
- Comfortable reviewing and guiding teams while still shipping clean, tested code efficiently.
I prefer contract-based, fully remote B2B roles with clear deliverables and a strong engineering culture. Open to part-time or full-time contracting with early-stage startups or product-led teams looking to scale systems thoughtfully.
If you need someone who can take ownership of architecture while executing hands-on, let’s talk.
Remote: Yes
Willing to relocate: No
Technologies: Python, Django, DRF, TypeScript, React, Angular, Next.js, Node.js, Nest.js, Docker, PostgreSQL, Redis, AWS, Supabase
