Why Me
Practical execution with clear ownership
I work with founders, agencies, and product teams that need dependable engineering delivery without long hiring cycles. I can step in for greenfield builds, feature sprints, and stabilization of existing backend services.
My background spans backend engineering, AI/RAG workflows, frontend integration, and cloud operations. I focus on clear communication, realistic milestones, and consistent delivery from implementation to handover.
How I work
- 01Discovery and scope
Understand goals, constraints, and user impact before implementation.
- 02Milestone delivery
Ship in clear weekly checkpoints so progress is visible and reviewable.
- 03Hardening and launch
Test critical flows, improve reliability, and prepare deployment safely.
- 04Handover and support
Provide documentation and post-launch support for smooth ownership transfer.
