Blockchain and Web3 consulting
Blockchain solves a very narrow class of problems, and costs a lot everywhere else. I step in early to tell you whether your project truly belongs there, then build it if it does.
Book a free callThe problem I solve
Many Web3 projects start from the technology rather than the need. Expensive development is committed for a use case a classic database would handle better. Conversely, some legitimate projects fail on infrastructure: unstable nodes, saturated RPC access, approximate security. Both mistakes show up early when you have already operated these systems.
How I work
Feasibility first
First question: do you need a blockchain at all? If the answer is no, I say so, and you save a development budget.
Architecture
Chain selection, data model, trade-offs between on-chain and off-chain. Decisions made here are expensive to undo.
Development
Smart contracts, API integration, decentralised applications. With the testing and review this kind of code demands.
Infrastructure
Industrialising nodes and RPC access: caching, rate limiting, supervision, automatic restart. This is where projects hold or fall in production.
Real example
Concrete example: for the Share3 platform, I industrialised blockchain access as a containerised service with caching, per-IP rate limiting, a health check every 30 seconds and automatic restart, across 3 networks served.

Frequently asked questions
Which chains do you work on?+
I have worked on Ethereum, Solana and Cosmos-based chains, in development as well as validator operation.
Do you give crypto investment advice?+
Never. My work is strictly technical and project-related. For financial questions, speak to a licensed professional.
Can you take over an existing project?+
Yes. An audit of the existing setup is often the best starting point, before deciding what to keep and what to rebuild.
How much does it cost?+
On a quote basis once scoped. The first discovery call is free.
My work is technical and methodological. It is neither investment advice nor legal or tax guidance on digital assets.
