PROFILE
Katerina Maneva
Worked on the nolus-money-market repository, delivering core backend and financial infrastructure for DeFi lending and borrowing. Focused on safety, maintainability, and precision, the work included refactoring financial math primitives, modernizing APIs, and introducing abstractions like Percent100 and Permilles to ensure bounds-safe calculations. Leveraged Rust’s type system, generics, and trait implementations to standardize arithmetic, error handling, and serialization across modules. Migrated away from external SDK dependencies, improved interchain messaging, and consolidated overflow handling for reliability. Enhanced test coverage and documentation, reorganized code for clarity, and enabled high-precision arithmetic using U256, supporting robust, scalable smart contract development.

Feb 1, 2026February 2026: Delivered core business value through SDK migration and API cleanups, stabilized finance primitives, and improved cross-chain capabilities. Key achievements: 1) Migrated away from neutron-sdk; introduced custom ProtobufAny and InterChainMsg with RequestPacketTimeoutHeight; removed neutron-sdk dependency. 2) Permilles API cleanup: new constructor, to_primitive usage, within() checks, and cleaned Display formatting. 3) BoundPercent/PercentUnits cleanup and related documentation, plus code organization improvements. 4) Coin amount handling refactor to primitive display (to_primitive) with tests updated. 5) Finance module cleanup and optimizations, plus expanded unit tests and test utilities. Additional improvements: repository hygiene (gitignore), cargo updates, and test coverage enhancements. Impact: reduced dependencies, more reliable finance math, clearer APIs, and faster cross-module integration.

Dec 1, 2025December 2025 highlights for nolus-money-market focused on safety, scalability, and maintainability of the finance stack. Major work delivered overflow-safe price totals, API standardization via From and new coin helpers (lease_coin/lpn_coin), and a broad finance core cleanup moving arithmetic to a dedicated module and replacing legacy primitives. LPP and Lease modernization improved safety and clarity with new coin usage and renamed assets; testing and documentation improvements (bnum in tests, Oracle tests, to_quote/from_quote tests) increased reliability. Finally, merge-conflict resolution and rebasing reduced churn, setting a solid foundation for 2026.

Oct 1, 2025October 2025 in nolus-money-market focused on precision, API modernization, and safety improvements. Delivered a unified Rational framework with implementations for SimpleFraction, Ratio, Percent, enabling accurate numeric representations across core types. Modernized the Fractionable API by migrating from FractionableLegacy to new Fractionable across Coin, Duration, and BoundPercent, introducing new implementations and removing legacy usage. Implemented Fraction<Percent100> for Percent100. Refactored Duration and interest handling to use safer Option-based results and updated annualized_slice_of() to use of() semantics. API naming and rational-type modernization (Rational replaces RationalLegacy, into_max naming adjustments), tightened safety with restricted visibility (Coin::amount), and performed extensive code cleanup, tests, and rebase fixes. These changes improve correctness, safety, and developer productivity, delivering tangible business value in lending/borrowing calculations and risk management.

Jul 1, 2025July 2025 monthly summary for nolus-money-market focusing on safety, correctness, and maintainability of percent-based financial calculations. Key changes delivered: - Introduced Percent100 type and standardized its usage across finance modules and tests to ensure bounds-safe percentage arithmetic and consistency, enabling safer financial calculations. - Refactored finance module to support temporary Add/Sub for BoundPercent, aligned calculations with Rational trait and Percent/Percent100 usage, and updated dependent tests. - Renamed Rational<U> to SimpleFraction<U> for clearer semantics across the finance codebase, with no functional changes. Note on quality improvements and fixes: - Test and test-support refinements were performed to accommodate the Percent100 and BoundPercent changes (test fixes and cleanup were applied during the refactor process). Impact: - Reduced risk in percentage calculations, improved code readability, and created a more maintainable foundation for future finance features. Technologies/skills demonstrated: - Rust type system, generics, and trait usage (Percent, Percent100, Rational/SimpleFraction). - Refactoring discipline, test-driven adjustments, and codebase hygiene. - Cross-module standardization to enable safer, bounds-checked financial computations.
