Engineering specialization
Backend-first engineering with complete product delivery.
I work across architecture, backend, frontend and infrastructure, with particular depth in financial and blockchain transaction systems.
Backend Architecture
API-first services, asynchronous processing, real-time communication, data consistency and secure financial workflows.
Trading Platforms
Market data, exchange integrations, swaps, order workflows, corporate wallets and transaction execution services.
Fullstack Delivery
Vue.js interfaces, admin systems, backend APIs, Docker deployments and complete products delivered from concept to production.
Professional positioning
More than a standard Fullstack Developer.
My work combines backend engineering, product architecture, blockchain infrastructure and practical frontend delivery. I design the systems behind the product: wallets, balances, approvals, transactions, scanners, APIs, webhooks and operational workflows.
Core engineering value
I turn complex blockchain requirements into usable systems.
✓
Translate product and business requirements
into secure technical architecture.
✓
Design systems around real transaction states,
confirmations, failures and recovery flows.
✓
Build backend, frontend and infrastructure
without losing consistency between layers.
✓
Deliver complete products from early concept
through deployment and production iteration.
Selected engineering achievements
Architecture and systems built from real product requirements.
Highlights from products involving blockchain custody, wallets, real-time applications and trading infrastructure.
Multi-chain custody architecture
Designed a B2B custody platform with custodial and non-custodial wallets, transaction execution, blockchain scanners, workspaces and API-based integrations.
Secure transaction approvals
Implemented configurable multi-approval workflows with distinct approvers, initiator restrictions, transaction thresholds and controlled execution.
Event-driven blockchain processing
Built scanner and webhook flows for transaction confirmations, balance changes, transaction events and real-time updates across product interfaces.
Product-to-production delivery
Delivered backend services, Vue.js applications, database models, integrations and deployments using Docker, Kubernetes and production web infrastructure.
