What I'm looking for

I'm looking to build and own high-impact web products end-to-end, working directly with founders, designers, and customers. I'm open to relocation to Helsinki and value roles where I can combine product delivery, technical ownership, and business outcomes.

I've founded and built Wishkr, an occasion-led gifting platform for the Indian market, from business proposal through production. I architected its FastAPI/PostgreSQL backend and Next.js customer, admin, and vendor applications, plus a WhatsApp gifting assistant and Razorpay marketplace payments.

As an independent contractor, I've built FastAPI and Next.js products for clients including Primacy, integrating wearable data through Terra API and a Gemini-powered AI coach. I also deliver accessible React and Next.js applications, headless CMS integrations, reusable design systems, and high-fidelity Figma implementations.

Previously, I led Sprinque's Merchant Control Center and Pay Page for B2B buy-now-pay-later workflows, helping support an MVP delivered in two months that enabled $1.7 million in funding. Across banking, fintech, and hospitality projects, I've focused on shipping practical products, improving operations, and owning outcomes beyond code.
