Blockchain Full Stack Developer Needed
We’re building a next-generation cryptocurrency portfolio tracker focused on accurate profit & loss (P&L) and cost basis calculations across both centralized exchanges and DeFi wallets. This is not a simple balance-tracking app—we’re reconstructing historical positions, linking related transactions, and producing reliable financial outputs.
We’re looking for a developer who is comfortable working with complex data flows, financial logic, and crypto APIs, and who can build clean, reliable systems—not just UI.
Key Responsibilities:
-Integrate with major crypto exchanges (read-only APIs) and on-chain wallets
-Implement historical P&L and cost basis calculations (no manual price entry)
-Build logic to link related transactions (swaps, staking, LPs, transfers)
-Support multiple portfolios/accounts
-Implement real-time and historical performance tracking
-Add customizable alerts and notifications
-Ensure correctness, edge-case handling, and data integrity
Required Skills:
-Strong experience in mobile or full-stack development
-Experience with crypto exchange APIs and/or on-chain data
-Solid understanding of financial logic (P&L, fees, cost basis)
-Strong debugging and edge-case handling skills
-Familiarity with clean UI/UX principles
Nice to Have:
-Prior experience building crypto, fintech, or accounting tools
-Experience with DeFi data structures
-Familiarity with Solana or EVM chains
Project Scope:
Medium-sized project (1–3 months). We’re looking for an intermediate to senior-level developer who has worked on similar data-heavy or financial products.
To Apply Please include:
-Relevant projects you’ve worked on (especially crypto or fintech)
-Which exchanges/wallets you’ve integrated before
-Your approach to handling historical P&L and cost basis
-Your availability and estimated timeline
