EVM APPLICATION ENGINEER · REMOTE
I build high-performance blockchain infrastructure,
on-chain market automations, and backend services.
I have 3+ years of experience building production-grade software in TradFi, and 2+ years building EVM/DeFi systems alongside it.

A real-time arbitrage engine on Base and Robinhood Chain. It finds price gaps across DEX pools and closes them in one atomic transaction.
- HOW IT WORKS
- Reads the sequencer feed directly and keeps an in-memory liquidity graph that updates only the affected pools. Worker threads search for profitable cycles in parallel. Arbitrage opportunities are executed through a gas-optimized flash-loan Solidity contract, with pre-trade simulation to avoid paying gas costs for missed opportunities.
- RESULT
- Market-event-to-decision latency under 10 ms
- 20,000 pools tracked
- 200+ arbitrages executed
SEQUENCER / WORKER THREADS / SOLIDITY
A self-hosted indexer that turns raw blockchain data into clean, queryable tables. It feeds the liquidity strategies below.
- HOW IT WORKS
- Fetches blocks and events via viem from providers like Alchemy. Polls the chain head. Recent data lives in PostgreSQL, older data in Parquet. Runs in Docker.
- RESULT
- Indexes 10 blocks/sec
- 15M+ events/day stored
- Full indexing costs ~$8/month in RPC compute units
VIEM / POSTGRESQL / PARQUET / ALCHEMY
A system that finds liquidity-providing (LP) opportunities on Uniswap and runs the full position lifecycle: entry, compounding and exit.
- HOW IT WORKS
- Scores pools by fees, volume and volatility using indexer data. Opens positions when a pool meets the entry rules. Compounding, harvesting and exiting are all automated through predefined strategies.
- RESULT
- 10+ positions managed concurrently
- Active strategies earn back their deployed capital in fees every ~10 days
- Passive positions auto-compound with no manual intervention
INDEXER / UNISWAP / DOCKER
One trading interface over many DEX protocols on many chains. It adds limit orders and route aggregation to DEXes that do not support them natively.
- HOW IT WORKS
- An ethers.js layer puts each protocol behind one adapter interface. The routing engine quotes all adapters and picks the best. Limit orders live off-chain and fire at the target price. The UI is built in Next.js, with usability in mind.
- RESULT
- Chain- and protocol-agnostic limit orders
- Adding a new DEX means writing one adapter

INDEPENDENT — EVM Application Engineer
I Design and build trading infrastructure, automation tools and backend systems for DeFi protocols. I work end to end, from Solidity contracts to the services that watch and act on them.

Simple systems age better.
Complexity is easy to add and expensive to remove. So I only add it when the problem truly demands it, never before.
“Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” — Martin Fowler
Build for failure.
On-chain markets never close, so the systems behind them can't either. I put reliability first: graceful failures, clear monitoring and safe recovery paths. That way, everyone still gets a good night's sleep.
“Everything fails, all the time.” — Werner Vogels
Good code should survive its author.
Someone else — including future me — has to be able to read this, trust it, and change it without calling me first. That means clear names, self-explanatory code and thorough tests.
“Code is read much more often than it is written.” — Guido van Rossum

Outside of work, I spend most of my time outdoors, walking or hiking in the mountains when I can. I also go to the gym, climb, and explore new places with my partner. And I like to keep up with the latest developments in my field and read related literature.
