Over deze dienst
Are you building a decentralized app, protocol, or indexing system requiring production-grade performance?
I am a Full-Stack Blockchain Engineer specializing in high-throughput infrastructure, smart contracts, and real-time indexers across Solana, Starknet, Ethereum, and Cosmos SDK networks.
What I Offer:
Smart Contracts: Production-ready Solidity contracts, custom business logic, ERC standards & unit testing.
Real-Time Indexers: High-throughput pipelines built with Yellowstone Geyser gRPC, Kafka/Redpanda, PostgreSQL & TimescaleDB.
High-Performance APIs: Scalable REST/gRPC backend APIs with strict input validation and backpressure streaming.
Routers & Decoders: Multi-hop transaction parsing and decoding for complex DEX aggregators.
Why Choose Me?
Optimized Performance: Sub-2ms network sync and high query capacity (>10k req/sec).
Fail-Safe Design: Reorg recovery state machines, strict memory bounds, and zero-crash architectures.
Please contact me before placing an order to discuss your project requirements!

Veelgestelde vragen
Which blockchain networks and ecosystems do you support?
I specialize in Solana (Yellowstone Geyser gRPC), Starknet, Cosmos SDK, and EVM-compatible chains (Ethereum, Arbitrum, Polygon) using Solidity, Go, Node.js, and Rust.
Do you provide the full source code upon completion?
Yes, clean, well-documented source code is included with full rights transferred upon order completion.
How do your indexers handle blockchain reorganizations (reorgs)?
Indexing pipelines feature built-in reorg recovery state machines and FIFO block ordering to prevent data gaps or corruption during network state changes.
Can you build custom APIs for my frontend or mobile app?
Yes, I develop REST and gRPC API layers connected directly to PostgreSQL/TimescaleDB databases for fast querying by Web3 or mobile applications.
