Direct architectural execution by senior engineer Mr Umer Malik with zero agency dilution.
Audited Solidity & Rust Smart Contracts
Security-hardened smart contracts built with OpenZeppelin standards, formal verification testing, and gas-efficient storage patterns.
RWA Real-World Asset Tokenization
ERC-3643 and ERC-1400 compliant security token architectures enabling compliant fractional ownership of Australian real estate and commodities.
EVM Web3 Wallet Integration (Web3Modal / Viem)
Frictionless Web3 wallet connectivity supporting MetaMask, WalletConnect, and account abstraction for seamless user onboarding.
High-Throughput Subgraph & Indexer Pipelines
Custom The Graph subgraphs and Node.js event listeners indexing on-chain transaction data for sub-second database queries.
Solana & Layer-2 Deployment (Arbitrum / Base)
Deploying high-throughput decentralized protocols on low-fee Layer-2 networks and Solana to minimize end-user transaction costs.
Smart Contract Auditing & Slither Static Analysis
Deep vulnerability analysis identifying reentrancy bugs, integer overflows, front-running vectors, and logic errors before mainnet deployment.
Why Australian Innovators Demand Senior Web3 Engineering
Smart contract bugs are irreversible once deployed on-chain. Here is why Australian teams trust Mr Umer Malik for mission-critical Web3 architecture.
Security-First Development & Comprehensive Testing
100% test coverage with Hardhat/Foundry, invariant testing, and automated Slither static analysis before any mainnet deployment.
Aggressive Gas Optimization
Optimizing storage slot packing and assembly logic to drastically reduce transaction gas fees for your users.
AEST / AEDT Real-Time Collaboration
Direct, synchronized working hours during the Australian business day for collaborative architectural planning.
Predictable AUD Milestone Billing & 100% Code Handover
Milestone-based sprint quotes in Australian Dollars (AUD), complete repository transfer, and Australian bilateral NDA.
Phased Delivery Roadmap & How This Project Runs
Structured from initial discovery call to production deployment and 100% intellectual property transfer.
Sprint 01: Tokenomics & Security Threat Modeling
Defining protocol specifications, token economics, permission hierarchies, and conducting comprehensive threat modeling.
Sprint 02: Smart Contract Engineering & Unit Testing
Developing modular contracts in Solidity or Rust, achieving 100% branch test coverage in Foundry or Hardhat.
Sprint 03: Testnet Deployment & Frontend dApp Hookup
Deploying contracts to Sepolia testnet, building responsive React/Next.js dApp interfaces, and connecting wallet providers.
Sprint 04: Formal Security Audit & Mainnet Cutover
Running automated static analyzers, remediating edge-case vectors, executing mainnet deployment, and transferring ownership keys.
