Backend Engineer specializing in TypeScript and Node.js, focused on building scalable systems with strong data integrity, secure authentication, and production-ready architecture. I’ve built multi-interface platforms, workflow-driven services, and currently contribute to a real-world product helping SMBs simplify marketing execution.

About Me

Building Reliable Systems That Power Real Products

I’m John Ughiovhe, a software engineer passionate about building scalable backend systems and modern web applications. I specialize in designing reliable APIs, secure server-side architectures, and backend systems that power real-world digital products.

My journey into software engineering started with curiosity about how applications work behind the scenes. That curiosity evolved into a passion for solving complex problems with code and designing systems that remain reliable, maintainable, and scalable as products grow.

I recently completed a Diploma in Backend Engineering at AltSchool Africa, where I was recognized as Best Learner. Through that experience and hands-on engineering work, I gained practical experience building backend services, full-stack applications, and production-style systems using modern development tools and workflows.

My work spans multi-interface platforms, workflow-driven systems, secure authentication architectures, and API-first applications. I’ve built projects ranging from backend systems supporting Web and CLI experiences to workflow engines with strict validation and data integrity rules, and I currently contribute to SEIL, a real-world product helping SMBs simplify marketing execution.

I enjoy thinking beyond endpoints and features, focusing on system design, developer experience, reliability, and building technology that creates measurable value for users.

Insighta Labs+

Insighta Labs+

IMPACT

  • Insighta Labs+ is a TypeScript/Express backend that powers a profile intelligence platform across both web and CLI interfaces. It provides secure GitHub OAuth (PKCE) authentication, role-based API access, deterministic natural-language search, and a unified token model, ensuring consistent behavior, security, and data integrity regardless of how the system is accessed.
Eventful - Event Ticketing and Management Platform

Eventful - Event Ticketing and Management Platform

IMPACT

  • Built a full-stack event ticketing platform that streamlines event creation, ticket checkout, and attendee management, replacing manual coordination workflows. Designed modular REST APIs using Node.js, TypeScript, and Express to improve scalability and maintainability, integrated Redis caching to reduce API response latency, and implemented a secure backend architecture with MongoDB to support long-term platform growth.
Invoice Workflow Engine

Invoice Workflow Engine

IMPACT

  • A full-stack invoice management system built with a backend-first architecture, supporting structured invoice workflows (draft → pending → paid), server-side validation, and dual persistence (PostgreSQL with automatic schema bootstrap and JSON fallback for local/test isolation). Designed for reliability across environments, with clean API design, validation boundaries, and testable data flows.
Guessing Game

Guessing Game

IMPACT

  • Developed a real-time multiplayer guessing game using Node.js, Express, and Socket.IO, enabling low-latency gameplay through WebSocket-based bidirectional communication. Implemented core game mechanics including timers, scoring, rounds, and player attempts while designing an event-driven architecture capable of supporting multiple concurrent users, alongside a responsive frontend built with HTML, CSS, and JavaScript.

Experience

Backend Engineer Intern

April 2026 – Present
HNG Tech·Lagos, Nigeria

IMPACT HIGHLIGHTS

  • Contributing to the backend development of SEIL, a guided marketing funnel platform helping SMBs generate and execute personalized marketing workflows through conversational onboarding, automated funnel blueprint generation, and guided activation flows.
  • Collaborating in a cross-functional team environment to build scalable APIs and workflow orchestration logic supporting MVP delivery under real product constraints and iterative development cycles.
  • Built Insighta Labs+, a multi-interface TypeScript/Express backend powering both Web and CLI experiences with secure GitHub OAuth (PKCE), role-based access control, deterministic natural-language profile search, and a unified token model ensuring consistent authentication and authorization across clients.
  • Architected secure authentication infrastructure with token rotation, hashed token storage, middleware-driven request pipelines, and route-scoped access enforcement to improve reliability and system security.
  • Built a backend-driven invoice workflow system supporting structured invoice lifecycle states (draft → pending → paid), PostgreSQL persistence with development fallbacks, schema-driven validation, and testable API flows.
  • Designed modular backend systems with clear separation between routing, validation, business logic, persistence, and error handling to improve maintainability and scalability across projects.

Backend Developer (Intern)

September 2025 – February 2026
AltSchool Africa·Remote

IMPACT HIGHLIGHTS

  • Built Eventful, a full-stack event ticketing and management platform that streamlined event creation, ticket checkout, and attendee workflows, replacing manual coordination processes with a scalable digital system.
  • Designed modular REST APIs using Node.js, TypeScript, and Express, and integrated Redis caching to improve response performance and support long-term scalability across backend services.
  • Developed a real-time multiplayer game system using WebSockets and Socket.IO, implementing low-latency bidirectional communication, event-driven game logic, timers, scoring systems, and concurrent user interactions.
  • Built a chat-based food ordering platform using NestJS and TypeScript, implementing modular APIs, session-driven workflows, and payment verification flows to improve user accessibility and transaction handling.
  • Designed backend systems supporting authentication, access control, relational data modeling, and payment integrations, strengthening experience with production-style application architecture.
  • Developed a content publishing backend with role-based access controls and reusable RESTful API structures for protected and public content operations.
  • Applied modern backend engineering practices including modular architecture, API design, validation, persistence design, and scalable system organization across multiple projects.
