A personal wealth-management platform for Indian households, with every investment, asset, loan, expense and goal in one place, plus a SaaS operator console to run it as a business.
PPF, EPF, NPS, SSY, SGB, FD/RD maths and Indian tax reports, alongside funds and stocks.
Track every family member separately and filter any screen by person.
Budget spend is calculated from real expenses, never typed in by hand.
Device and session control, login history, 2FA for admins and a full audit trail.
A locked OpenAPI contract serves web, admin, iOS and Android.
Every client builds against the same OpenAPI schema. Customers and admins sign in on separate tracks, so an admin token never works on customer routes or the other way round.
The same backend runs a consumer finance app and the operator console that manages its customers, plans and support.
Eight KPIs, net-worth trend, asset allocation, top movers, upcoming payments and recent transactions.
A 22-type instrument catalog with FD/RD maturity maths, plus mutual funds (XIRR, 1Y return) and stocks (P&L).
Purchase vs current value for assets; EMI, tenure, rate and repayment progress for loans.
A categorised cashbook with trend and category charts.
SIPs, EMIs, premiums, bills and subscriptions with a paid/upcoming record for every month.
Actuals with a forward projection, goals, and budgets tracked against real spend.
Net worth, allocation, income vs expense, capital gains, insurance, loans, goal progress and tax.
Customers, advisors, plans, subscriptions, invoices, coupons, support tickets, staff roles and platform KPIs.
How the hardest calls were made: what else was on the table, why it lost, and what the chosen design costs.
The data layer moved from Motor to PyMongo’s native async driver, and mocking libraries lagged behind it.
Tests start a throwaway mongod and run every query for real.
Slower test runs and MongoDB needed on CI, in exchange for tests that catch real query bugs.
Customer auth with signup, OTP verification, password reset, refresh tokens and logout, plus device and session management with forced logout.
Permanent human-readable customer IDs (AR100001), per-platform device capture and a filterable login history.
Investments ledger with a 22-item instrument catalog and FD/RD maturity maths; dedicated mutual-fund (XIRR, 1Y return) and stock (P&L, LTP) modules.
Assets and liabilities with EMI, tenure, rate and repayment progress.
Cashbook for categorised income and expenses, and recurring payments (SIPs, EMIs, premiums, bills) with a paid/upcoming log for every month.
Cash flow with actuals and a forward projection; goals and budgets whose spend is computed live from real expenses.
Dashboard with 8 KPIs, a net-worth time series, allocation, movers, upcoming payments and recent transactions.
Eight report types: net worth, allocation, income vs expense, capital gains, insurance, loans, goal progress and tax.
Multi-family-member tracking under one login, ⌘K federated search, and import/export.
Super Admin console backend: customers, advisors, plans, subscriptions, invoices, coupons, support tickets, staff roles and a platform dashboard.
Separate admin auth track with 2FA by default, rate-limited login, and audited, short-lived customer impersonation.
Every admin change written to an audit log with who, what, old value, new value and IP.
Tests run against a real ephemeral MongoDB instance rather than a mocked database.
The code is private, but I'm happy to demo the product and talk through the architecture. I'm available immediately for senior roles and contract work.
