Aditya Rouniyar

About

Product-minded full-stack engineer at a B2B startup who ships high-stakes customer-facing features fast: delivered a Spanish AI support agent in 2 weeks by benchmarking LLMs and using native Spanish system prompts, reaching 90% resolution. Built the company’s first monetization system (hybrid subscription + usage) with Stripe/Firebase, emphasizing secure JWT-based flows and idempotent webhooks, and led a microservices decoupling effort that cut developer onboarding time by 50%.

Key Strengths

• Delivered urgent Spanish-language AI agent in 2 weeks (vs 4-week standard timeline)

• Stakeholder management with lightweight, data-driven communication (demo-based buy-in; daily metrics via golden set)
• Built end-to-end monetization system with hybrid billing (subscription + pay-as-you-go) using Stripe + Firebase
• Designed secure payment architecture (untrusted client principle, JWT verification, webhook signature verification)
• Implemented idempotent webhook processing to prevent double-crediting (Stripe event_id deduplication)
• Architected microservice decoupling to improve deployment velocity and reduce onboarding time by 50%
• Rapid incident response and production fix without impacting main website (patched decoupled admin dashboard within hours)
