Solana programs
Clean account design, PDAs and CPIs, and validation on every instruction. Readable, testable and ready for an audit.
// About
One engineer across the whole stack, from account layout to the button you click.
I'm a full-stack and blockchain developer based in Davao City, Philippines. I write on-chain programs in Rust and Anchor, the TypeScript clients and React frontends that talk to them, and the off-chain automation (keepers, cron jobs, RPC setup) that keeps a protocol running.
As founder of NECXSOFT, I lead discovery, architecture and every client conversation end to end. Clients work with me directly, with no account managers in between, and they see a working devnet demo before anything is final.
vision
To be a trusted technology partner that turns ideas into reliable, impactful products on Solana.
mission
To deliver practical Solana and AI solutions that help businesses and protocols improve, grow and reach their goals.
// What I build
Solana engineering, from the program to the product.
I cover the on-chain logic, the interface people use and the automation around it, so nothing gets lost between handoffs.
dApps & wallets
Fast web frontends with wallet connection, transaction building and confirmation states that users can follow.
Tokens & NFTs
SPL and Token-2022 launches with transfer hooks, fees and on-chain metadata, plus Metaplex Core and compressed NFTs.
DeFi integrations
Swap routing, oracle price feeds, staking, escrow and vesting flows, with clear failure handling.
AI agents on Solana
LLM agents that read on-chain data, explain it and act on it, with spending limits and human approval built in.
Infra & deployment
Keepers on serverless cron, RPC providers, staged devnet → mainnet releases and safe program upgrades.
// Selected work
Projects you can open and use.
I'd rather link to working products than describe them. Open the live build and try it yourself.
Live on Solana devnet
Necxsoft Perps & Predictions
A perpetual futures exchange on Solana, with Predict and Earn sections in the same app. Traders post USDC collateral and go long or short on SOL-PERP with up to 50× leverage.
- Market orders fill at the oracle price; limit orders rest in a shared on-chain order book
- Take-profit, stop-loss and stop-entry orders, with liquidation price and fees shown before signing
- Skew-based funding, plus hourly market history and a liquidation feed stored on-chain
- Rolling price prediction markets, opened and settled by an oracle-authority keeper
- Keeper hosted on Cloudflare Workers cron; program tested with LiteSVM

- missing signer check covered
- account owner check covered
- arithmetic overflow covered
- PDA seed collision covered
- closed-account reuse covered
