Cover image for Overview I led development of Core's
Overview I led development of Core's DeFi integrations for core.app/deposit (https://core.app/deposit) and core.app/borrow (https://core.app/borrow), bringing Aave and Benqi market interactions directly into the Core dApp experience. The goal was to let users supply and borrow without having to leave Core, while preserving the same trust model users expect from onchain finance: direct wallet signatures, transparent contract calls, and predictable transaction outcomes. What We Built We shipped two production user flows: Deposit: supply supported assets into protocol markets and track updated positions. Borrow: open and manage borrow positions with real-time collateral and utilization context. Both flows were designed to feel native to the Core product while still exposing protocol-level information users need to make safe decisions. Technical Approach The integration stack centered around React, Typescript, and Wagmi for wallet + chain orchestration. Under the hood, we integrated directly with Aave and Benqi contracts rather than proxying protocol actions through an offchain layer. This gave us tighter control over call construction, clearer error surfaces, and stronger alignment with protocol behavior. Key implementation areas included: Contract write/read hooks for supply, withdraw, borrow, and repay lifecycle actions. Market and account state normalization across protocol-specific response shapes. Unit/decimal conversion utilities to avoid precision and display drift. Gas-aware UX states and transaction feedback for multi-step actions. Defensive handling around approvals, allowance edge cases, and chain-specific failures. UX and Product Considerations DeFi interactions can fail for many reasons, so we treated status and clarity as first-class features: Preflight checks before submission to reduce avoidable failures. Explicit loading/success/error transaction stages. Contextual copy around collateral health and borrowing implications. Predictable refresh behavior after confirmations so balances and positions settle cleanly. Impact This work enabled Core users to access lending and borrowing opportunities from a single interface, reducing friction between discovery and execution. From an engineering perspective, the project established reusable DeFi integration patterns in Core Web that can be applied to future protocol integrations with less implementation overhead.

Cover image for I’ve been working on a
I’ve been working on a healthcare web app lately. Focused a lot on security, clean UI, and making it actually simple for real patients and doctors to use. It’s been challenging but honestly really rewarding to build something that can help people in real life.

Cover image for Streamlined Messaging Platform for Dental Office Efficiency
Dental offices often handle patient messages, appointment questions, billing requests, and follow ups across too many disconnected channels. This project was built to bring patient communication into one clean messaging platform so staff could respond faster, stay organized, and manage conversations with less manual work. I designed and developed a real time messaging system with patient conversations, inbox filters, message status, team assignment, routing rules, quick replies, internal notes, and conversation history. The platform helped staff manage website chat, SMS, and patient inquiries from one simple dashboard. My work covered the frontend messaging interface, backend API structure, WebSocket based real time updates, conversation routing logic, user roles, activity tracking, debugging, and production support. The result was a practical communication tool that helped dental offices improve response visibility, reduce missed messages, and manage patient conversations more confidently.

Cover image for Many businesses manage customers, support
Many businesses manage customers, support requests, tasks, and follow ups across too many separate tools. This project was built to bring those daily workflows into one clean internal dashboard that is easier to see, manage, and scale. I designed and developed a full stack CRM and support platform with customer profiles, ticket tracking, task management, activity history, real time updates, and workflow automation. The goal was to give users a simple place to organize customer operations without losing visibility across requests, priorities, and internal work. My work covered the frontend dashboard, backend API structure, data flow, automation logic, real time communication, debugging, and production support. The result was a practical business tool that helped reduce manual tracking, improve workflow visibility, and make customer support operations easier to manage with confidence.

Cover image for Licensing is one of those
Licensing is one of those backend systems that users rarely think about until something breaks. If a license fails, a product activation is blocked, or a deployment goes wrong, the support team needs clear visibility fast. This project focused on building the backend control layer behind a software product. The platform handled product activations, license validation, entitlement checks, customer access, device history, deployment status, API activity, and system audit logs from one internal admin dashboard. I built the system with reliability in mind: clear API logic, structured license records, searchable logs, deployment tracking, environment health checks, and automation tools for recurring backend operations. The dashboard gave administrators a practical way to see what was active, what failed, and what needed attention without digging through disconnected tools or server logs. The result was a more dependable operations system for managing licenses, deployments, access control, and backend support workflows with better visibility and less manual troubleshooting.

Cover image for Many businesses lose time and
Many businesses lose time and potential customers because new leads come from different places like website forms, ads, referrals, chat widgets, and email. This project was built to capture those leads in one system, organize them automatically, and help users follow up faster without relying on manual tracking. I designed and developed a lead intake and automation platform with lead dashboards, source tracking, status management, assigned owners, follow up stages, task creation, email notifications, activity history, and automation workflows. The goal was to make the full lead process easier to manage from first inquiry to follow up and conversion. My work covered the frontend dashboard, backend API structure, automation flow logic, lead data handling, notification setup, activity tracking, reporting views, debugging, and production support. The result was a practical workflow system that helped reduce missed leads, improve response speed, and give businesses a clearer view of their sales pipeline.
