Estimate Notes
- Rates reflect senior full-stack + quantitative finance expertise. VSOP87 and Keplerian mechanics are specialist skills commanding a premium.
- Hours are estimates based on actual complexity observed during development. Planetary engine and multi-chain resolver were the most time-intensive components.
- Frontend rates are lower than backend/quant rates due to the availability of shadcn/ui and Tailwind tooling reducing raw implementation time.
- Does not include ongoing hosting, API costs (CMC, Etherscan), or future feature development (Liquidity Engine, Jupiter alerts, 100k+ DEX scale-up).
- All figures in USD. Estimate prepared October 2026.
