What I'm looking for

I'm looking to build AI-enabled mobile, fintech, and workflow products where I can combine Flutter engineering, backend architecture, and technical delivery leadership across cross-functional teams.

At Genix Pharma, I shipped an offline-capable Qwen 2.5 AI assistant for the DIGILYZR field-sales platform and built reusable AI services for a four-developer squad. I also automated expense, payment, approval, budget, incentive, and ROI workflows for a nationwide field sales force.

I've led Agile delivery across concurrent product tracks, coordinating design, QA, backend teams, and external API vendors while delivering eight-plus sprints on time with no scope overruns. My work has improved API response times by 30%, query execution by 40%, and crash rates by 65% for products serving 5,000+ daily active users.

Alongside Flutter, I build Python and Flask AI backends with multi-tenant architecture, WebSocket chat, RAG, LLM orchestration, and secure data layers. I bring software engineering and project-management experience to practical products that work reliably online and offline.
