Backend-Focused Full-Stack Engineer
Build reliable systems.
Ship scalable products.
I design and build APIs, data models, authentication, background jobs, real-time systems, and production-ready web apps — NestJS, Express, PostgreSQL, MongoDB, and Redis, with Next.js when the product needs a UI.
Work
Featured production systems — open a case study for problem, architecture, decisions, and how the pieces fit together.

01 · Commerce
Live apparel commerce — faceted search, variant stock reservations, and a role-gated NestJS admin API that keeps checkout and inventory consistent.

02 · Wholesale
Wholesale cabinetry for dealers and showrooms — verified accounts, catalog checkout, and realtime admin messaging across three production apps.

Conference ops platform — QR check-ins, exhibitor lead capture, JWT RBAC, and Socket.IO sync with duplicate-safe writes.
Expertise
Backend first — then data, async work, realtime, interface, and delivery.
APIs, auth, validation, and service boundaries — the core of how I ship production systems.
Relational and document modeling, ORMs, indexing, and integrity under concurrent writes.
Background work off the request path — queues, workers, and cache for recovery and heavy jobs.
Event-scoped sync, presence, and low-latency channels without racing domain writes.
Storefronts, dashboards, and operator UIs kept thin on business rules.
Containers, cloud delivery, reverse proxies, and the APIs products depend on.
Experience
Client platforms, event systems, and team delivery — with APIs, data models, and realtime features.
Sparktech Agency
Event platforms — Node.js APIs, MongoDB models, JWT RBAC, and Socket.IO realtime alongside React/Next.js clients.
Own backend delivery on client event systems: API design, data modeling, access control, and realtime features, integrated with frontend and mobile teams.
React/Next.js clients over Express + TypeScript with MongoDB, JWT-guarded routes per persona, and Socket.IO for event-scoped realtime — presentation, transport, validation, and domain logic separated.
Softvence
Internship focused on Node.js APIs, PostgreSQL with Prisma, and React integration against REST contracts.
About
A backend-focused way of working: understand the problem, design the structure and data movement, then ship something that holds up in production.
I build full-stack products with a backend bias — systems where data stays consistent, APIs stay predictable, auth is intentional, and slow work moves to background jobs instead of the request path.
From idea to production
Map the real problem, constraints, and outcomes — then break work into features, dependencies, and edge cases before code.
Choose structure for change, then trace request → logic → storage → response so behavior stays consistent and predictable.
Modular code with clear ownership: validation, error contracts, auth, and security as part of the product.
Happy paths are not enough. Check failures, integrity, API contracts, and the cases users hit when things go wrong.
Fix what hurts, move slow work off the request path, leave room to grow, then watch production and keep refining.
