PROFILE
Dusan Brajovic
Worked on InjectiveLabs/cosmos-sdk, delivering seven features over five months focused on blockchain backend development, observability, and secure transaction workflows. Leveraged Go for module management, dependency upgrades, and cryptography enhancements, including raising staking commission rates and implementing safer fee grant validation. Introduced multisignature transaction support using EIP712v2, extending the sign mode handler to enable secure multisig operations for Cosmos-based wallets. Enhanced platform stability by modernizing Ledger signing workflows and improving SDK compatibility. Improved system observability through metrics tagging and lifecycle tracing, upgrading dependencies to maintain compatibility and streamline future releases. Maintained clean commit hygiene and ensured CI readiness throughout development.

Apr 1, 2026Month: 2026-04 — InjectiveLabs/cosmos-sdk Key features delivered and business value: - Dependency upgrades for Feegrant and CometBFT to improve compatibility and stability. Updated feegrant's go.mod and bumped CometBFT to a newer version, addressing compatibility constraints and reducing upgrade risk. - Block Lifecycle Observability: BeginBlocker/EndBlocker tracing and timing metrics across modules to boost performance monitoring, debugging capabilities, and operational visibility. Major bugs fixed: - Resolved maintenance gaps in dependency management by correcting feegrant go.mod and applying a CometBFT version bump, reducing potential build and runtime instability. Overall impact and accomplishments: - Enhanced stability and interoperability of the cosmos-sdk stack with newer dependencies. - Improved observability and traceability of critical ABCI lifecycle phases, enabling faster issue diagnosis and performance tuning. - Lays groundwork for more proactive performance optimizations and smoother upgrade paths in future releases. Technologies/skills demonstrated: - Go module management and dependency upgrades - Instrumentation and tracing across modules (ABCi lifecycle: BeginBlocker/EndBlocker) - Metrics collection and cross-module observability - Clean commit hygiene and maintainability practices
