About

I am a Software Developer and Open-Source contributor specialising in Frontend Engineering, UI architecture, and scalable system design. I enjoy exploring modern JavaScript frameworks and building high-quality user interfaces, along with creating open-source tools and NPM packages. I currently work as a Founding Engineer at Composio, where I helped architect the Rube MCP Platform and built core systems across authentication, real-time AI orchestration, usage-based billing, and multi-tenant infrastructure. I also contributed to Composio’s 30K-star TypeScript SDK and built the MCP Dashboard and internal design system. Previously, I worked as a Senior Frontend Engineer at Ernest and Razorpay, leading product development, implementing large-scale UI systems, improving performance, and delivering key user-facing financial features. I’ve built multiple products like Dora AI, Twinder, and various open-source tools, many of which gained thousands of users and community traction. I also speak at tech meetups on topics like MCP, animations, and modern frontend engineering.

Software Engineer at Emergent, Dec 2025 - Present · 9 mos, Bengaluru, Karnataka, India, Building Wingman (getwingman.com / app.emergent.sh/wingman) 1. AI Product Ownership: Owned Emergent's consumer AI agent: sole-authored a ground-up React client rewrite with streamed multi-turn agent runs and live tool-call UX, shipped Python gateway and Go orchestrator changes, and launched it on its own domain via Cloudflare edge routing. 2. Prompt Engineering & Experimentation: Built LLM-generated first messages on the team's repo-versioned prompt registry (via llm-proxy), a typed SeedMessage contract seeding greetings into multi-turn context, and Unleash-based prompt-variant A/B tests with sticky per-agent persistence. 3. Agent Cost Controls: Designed kill criteria for runaway agents: semantic-failure detection in Go (5+ tool errors, 50%+ error rate) auto-pausing schedules wasting ~750 tool calls/day, plus per-project credit limits across agent surfaces. 4. AI Observability: Built AI telemetry: PostHog session replays with all chat content masked, a New Relic taxonomy splitting one catch-all stream error into 7 diagnosable categories, and time-to-first-response metrics. 5. Streaming Reliability: Hardened SSE agent streams end to end: cursor-aware reconnect with history recovery, mid-run tool-call resume after refresh, and keepalive retries with polling fallback. 6. Backend Latency: Cut agent-provisioning latency (p50 744ms baseline) by moving a blocking identity seed into a Redis SET-NX background task and removing 3 I/O calls per record from the list endpoint (tests assert zero per-record I/O). 7. Payments: Built subscription paywall across Stripe, Razorpay/PagBrasil, and Paddle, closing 6 pricing-parity gaps with display-vs-checkout parity tests, plus regional INR/BRL pricing. 8. Edge Infra & Progressive Delivery: Built canary/A-B rollout infra in a Cloudflare Worker with sticky cookies and a rollback-by-default kill switch (prod ramps 20% to 100% in days), plus per-PR preview deploys and CI regression gates.

Founding Engineer at Composio, Nov 2024 - Dec 2025 · 1 yr 2 mos, San Francisco, California, United States, Founding Engineer Built - Rube (rube.app): One universal MCP for everything 1. Architected the Rube MCP Platform: Designed and built a universal MCP integrating 600+ apps, owning full-stack architecture with multi-tenancy, RBAC, and team management. 2.
