Senior Software Engineer and Product Engineer

I am building Herald, an AI-agent marketplace that provides access to more than 2,100 tools from over 75 providers through a unified balance. The product supports tool discovery and ranking, price locking, metered billing, remote MCP access, CLI access, REST APIs, and agent skills for clients such as Claude Code, Cursor, and OpenCode.

I previously built the Agent Commerce Protocol on 0G, including smart contracts for agent identity and job escrow, the hrld CLI, and agent integrations for autonomous hiring and payments. I also contribute to x402 payment infrastructure and cross-chain agent commerce capabilities.

I designed the architecture for an intent protocol connecting Ethereum Base and Stellar, enabling cross-chain intent execution. I also designed and implemented a secure Stellar treasury wallet using Coinbase Developer Platform and AWS KMS.

I built transaction batching through EVM smart accounts and Stellar multi-operation transactions, reducing gas costs by approximately 95%. The protocol was delivered for the bridge.rozo.ai product.

I architected and built an intent quote and order aggregation system across Across, deBridge, Wormhole Settlement, and LI.FI. The platform provided real-time quote and order broadcasting and cross-chain status tracking across EVM and Solana networks.

I owned the system end to end using Bun and TypeScript, created an adapter pattern that reduced protocol integration time, and operated AWS ECS infrastructure with Terraform, Docker, DocumentDB/MongoDB, PostgreSQL, and Redis/Valkey. I also implemented GitHub Actions CI/CD workflows for testing, builds, and releases.

I delivered a production-ready marketplace UI within two weeks, implementing the home page, domain search, and domain exploration experiences. I also drove design-to-implementation refinement through QA.

I built a backend integration layer for domain registrar APIs, enabling registration, migration, and user transitions away from a sunsetting domain provider.

I built and architected a custody wallet system on the Sui network, automating deposits and withdrawals that previously relied on a manual third-party payment process. The solution reduced processing time from approximately one hour to approximately fifteen minutes.

I developed API infrastructure with Bun, Hono, and PostgreSQL, and created a Rust-based Sui blockchain indexer. The indexer used Redis publishing and subscriber patterns to detect deposits in roughly 800 milliseconds for real-time processing.

I automated organization-wide GitHub access control by creating a GitHub Action that managed member permissions and roles from repository YAML configuration. This eliminated manual permission management across the company.

I also built GitHub Wizard, an internal Chrome extension that enforced company task-management guidelines and standardized workflow practices across the team.

I extended backend payment infrastructure to support TON and Solana/SPL token payments, expanding the available payment rails. I also developed backend services for a Telegram-based task and rewards platform.

I built and deployed non-custodial payment smart contracts on the Internet Computer Protocol, enabling trustless merchant payments without custodial intermediaries.

I integrated the TestGorilla assessment platform for candidate screening and developed dynamic MongoDB data-filtering pipelines. I also implemented real-time WebSocket chat functionality.

My work focused on backend integrations, data processing, and interactive platform capabilities.

I built a high-engagement website using React, Next.js, Tailwind CSS, and GSAP animations. The product supported a Bitcoin NFT campaign.

The campaign marketed 51 NFT Odysseys at 0.01 BTC each and generated approximately 14,000 USD in sales during a period when Bitcoin traded near 27,500 USD.

I worked as a software engineer on product development and application delivery. My experience included building production software across frontend and backend systems.

I contributed to implementation work in a full-time engineering capacity for the Indonesia-based company.

I developed custom Odoo modules for inventory, manufacturing, and payroll, including Talenta HRMS integration. I also integrated Ellipse EAM software to streamline operational workflows.

I built custom desktop applications integrated with Microsoft Dynamics NAV using .NET Framework and C#. These applications supported ink estimation and sales forecasting to improve production planning accuracy.
