Ibex LabsSolana / Rust / backend systems
Production engineering for onchain systems.
I'm Alex, a senior backend and Solana engineer. I build Solana programs, Rust/TypeScript backend services, and the operational glue around real onchain products.
Led Render ETH -> Solana migration work
Building onchain lending infrastructure for CFi
Backend and distributed systems background
Solana-first, Sui-capable
Proof
Work that maps real businesses onto Solana.
ETH -> Solana migration
Led core Solana protocol and backend work for Render's migration from Ethereum to Solana, including emissions, bridging, rewards, accounting, dashboards, and production operations.
- Burn-and-mint equilibrium implementation
- Wormhole bridge relayer and adhoc exchange migration support
- Reward automation for node operators, migration incentives, and partners
- Solo through initial protocol, backend, ops, and frontend work end-to-end; hired engineers afterward and helped hand off
Technical details->
- Implemented Render's burn-and-mint equilibrium model on Solana: scheduled RENDER emissions plus a separate process that listened for completed render jobs and bought/burned Solana RENDER as a function of ETH RNDR spent.
- Built token bridge flows so users could convert ETH RNDR into Solana RENDER through Wormhole, including incentive mechanics for early migration and support around large CEX migrations.
- Automated network payment channels: weekly node-operator rewards, monthly upgrade rewards for migration participants, and partner payouts for nodes also doing compute on networks like io.net.
- Wrote Solana programs in Rust for emissions, BME, bridge-side token movement, tokenized network entities such as render nodes, and releasing multiple reward channels.
- Built TypeScript servers and cranker jobs for serving/indexing data from Redis/Postgres and orchestrating protocol operations against Solana.
- Built the Solana-side bridge relayer for redeeming Wormhole VAAs into RENDER.
- Built Postgres-backed dashboards for node operators and holders to track payments and network stats, plus internal accounting dashboards for movement tracking and reporting.
- Ran the production stack on Kubernetes with Grafana, Prometheus, Alertmanager, Loki, Tempo, PagerDuty, Vault/bank-vaults secret injection, and Nginx ingress.
Onchain lending infrastructure
Building an end-to-end onchain system for agricultural lending: an Anchor protocol, Bridge on/off-ramp integration, worker jobs for ACH-driven state changes, and frontend workflows for dealers and farmers.
- Role-based lending protocol for institutional and retail lenders subsidizing farmers
- Onchain loan origination, management, draw tranches, interest accrual, repayment settlement, and vault deposits/withdrawals
- Bridge (Stripe) on/off-ramp integration plus ECS workers for ACH movement and onchain state advancement
- Dealer and farmer frontend workflows for repayments and obligation monitoring
Technical details->
- Anchor protocol for institutional and retail lenders to subsidize farmer financing, with role-based ACLs across lender, dealer, farmer, and protocol operations.
- Onchain origination and management of loans, including creation of draw tranches as farmers spend against approved financing.
- Interest accrual on individual draw tranches, with settlement flows covering farmer repayments, lender vault accounting, and dealer-covered farmer interest.
- Onchain vault flows for lenders depositing into and withdrawing from lending pools.
- Bridge (Stripe) integration for seamless fiat on/off-ramp flows around protocol activity.
- ECS worker jobs that listen and poll for ACH fund movement, then advance onchain state and trigger accrual/settlement work.
- Frontend surfaces for dealers and farmers to execute repayments and monitor outstanding obligations.
Solana products + low-latency backend
Built across Nation's Solana ecosystem: the core DAO platform, Vellum for distributed document signing, and Caro, a real-time auction engine embedded into Shopify storefronts.
- Core Solana DAO platform for organizations, funds, voting, and proposals
- Vellum: DocuSign-like document signing on Solana with GPT-assisted drafting and post-signature actions
- Caro: real-time auction engine served as an embeddable Shopify widget
- Full-stack product work across Solana programs, backend services, frontend, and infrastructure
Technical details->
- Nation core started as a DAO platform on Solana, letting users create organizations, collect funds for causes, vote on proposals, and manage organization workflows.
- Vellum was a Next.js/Vercel product backed by Supabase for Postgres, realtime sockets, and blob storage, with Solana Rust programs for writing documents onchain and executing post-signature actions.
- Vellum included GPT-4-assisted document drafting and post-execution actions such as transferring funds after a document was signed.
- Caro implemented several real-time auction formats as a Shopify widget that could be embedded into storefronts.
- Caro began as a Rust backend using Actix, with an HFT-like design where each auction was assigned to a node and loaded in memory for low-latency bids/checkouts.
- The Rust service was load-tested around 500 bid requests/sec on a single Docker instance, then later ported to Deno because the service was effectively I/O-bound and the development loop/tooling were much faster.
- Moved auction state from in-memory plus async Postgres persistence toward Redis and Lua scripts where atomicity was needed, while preserving similar performance characteristics.

Where I'm useful
The technical surface I cover.
Best fit is Solana/Sui, RWA, credit, stablecoin, payments, migration, and protocol-adjacent teams where backend systems and onchain code have to work together cleanly.
