You stay on the forefront of AI, agentic automation, and modern payments. You evaluate integration paths and propose improvements proactively. You bring architecture and product ideas, not just code. You thrive in environments where requirements evolve. You think in systems, offer opinions, and challenge assumptions constructively.
