I’m Rizwan, an FDE with domain expertise in AI, observability, and fintech.
Frontend, UX, and 5+ years of attention to the details.
Sound fundamentals. From the browser to the backend.
Talk to customers, test ideas, and bring the right team together.
AI observability · Live demo
I led revamps of end-to-end tracing, monitoring, and evaluation workflows, built a new playground for prompt experiments, and redesigned dashboards with resizable, reorderable layouts, time zones, and auto-refresh. This work contributed to Respan’s growth to $1M+ ARR.
Product engineering · Case study
I joined as Respan’s first offshore engineer, working across full-stack engineering, product, and design. Alongside shipping the product, I helped scale the team to eight engineers across infrastructure, backend, product engineering, and design. A closer look at my work from April to October 2026.
OPEN SOURCE · AI TOOLING
I improved Last9’s MCP server for reliable AI-assisted investigations across logs, traces, and metrics. My contributions include richer tool context, consistent time-range handling, safer query validation, fixes for trace lookups, and direct links from tool results to the Last9 dashboard.
