Aditya Joshi

Founding Engineer (Forward Deployed) · EV fleet platform · Remote

• Brought in to find and fix the platform's hardest problems, owning the fleet operator experience end to end, from onboarding and partner feeds to live monitoring and monthly reports, across 3,000+ EVs and 3.7M events a day.
• Built route planning in 2 weeks, a feature the team had never cracked, powered by an in-house routing engine for all of India that handles 2,000+ routes a second on just 2 CPUs, with 1,000x room to grow at a fixed cost.
• Restored operators' trust in their data by reviving a partner feed that had dropped 613k packets, zeroing 705k impossible-speed readings and ending 6.8M junk errors a week sent to the partner.
• Led fleet onboarding for a national battery-swap network and a new OEM partner, then architected self-serve onboarding so business teams can launch new fleet customers without engineering in the loop.
• Single-handedly built BatteryFlow Rental for riders and warehouses in 18 days (181 commits, 38 PRs), with verified payment webhooks, OTP login and tenant isolation tests that fail the build.

Sole Founding Engineer · Freight marketplace · Remote

• Turned the founders' brief on scale, cost, legal and tax compliance into a live freight marketplace for shippers, carriers and drivers, owning every layer from design to hosting, from zero to its first paid trip in 4 months.
• Gave shippers quotes that cover the real cost of a trip, replacing flat pricing that underpriced fuel by 38% with a 4-layer pricing engine, built in one day, that matches the fleet's own cost model to 0.5% median error.
• Restored production delivery after 3 weeks of silent deploy failures by rebuilding CI/CD with health probes, then shipped 115 production deploys in 31 days across 7 microservices, authoring 125 of the first 126 PRs.
• Protected shipper and carrier accounts before launch by closing 34 review findings in 2 weeks, including open writes to the pricing tables behind every quote and reset tokens that worked as full logins.

Blockchain Developer (part-time) · Janction DEX on JASMY Chain · Japan (Remote)

• Custom-built swap execution for Janction DEX, a Uniswap V3-style exchange, around the client's Japan-specific market requirements that standard DEX logic could not handle, plus its Subgraph analytics.

Research Intern · Ethereum and Starknet core infrastructure · London (Remote)

• Joined the core infrastructure team behind one of Ethereum's leading execution clients to work on Juno, Nethermind's Go full node for Starknet, across P2P networking, chain sync and the JSON-RPC API.
• Chased a P2P bug where Juno nodes never rejoined peers after going offline and briefed the core maintainers.

Rust, Bash · 4 merged PRs

• Wrote the 2 security fixes in Zebra v6.2.2, full node of a $26B+ privacy network, with both merged in 31 hours.
• Eliminated a shell-injection path in zebrad-log-filter by reproducing it with a crafted log line and rewriting the filter in pure Bash, so a malicious log line can no longer run commands on a node operator's machine (#11050).
• Stopped the Elasticsearch password leaking into the startup config dump with a RedactedString type (#11051).

TypeScript, viem, Uniswap V2 AMM math, Flashbots, ENS

• Cut the modeled sandwich-attack loss on a $660K (250 ETH) swap from $35.9K to under $1K, a 97% reduction for DeFi traders, by simulating the attacking bot on live Ethereum data and picking the cheapest safe route.
• Replays the attack in exact Uniswap V2 math and searches up to 1,100 public and private route splits per trade.
