Backend Engineer

Muiz Oyebowale

I build the parts nobody sees, and that's exactly how I like it. I've got your backend.

not all heroes wears cape, some quietly build infrastructure that keeps working when it matters.

Who is this?

A backend engineer who cares about the parts of a product that only get noticed when they break. I build APIs, data pipelines, payments, and queues. I keep them reliable, correct, and boring, so nobody has to think about them. And I'm pointing the same attention at AI and ML.

Career

Where I've done this.

HNG Internship, Anvila & Insighta Labs

Internship

Tech Lead / Backend EngineerApr 2026 to Jun 2026

Tech lead over an 11-engineer backend and frontend team building Anvila, an AI-agent manifest generator, shipped in under a month. Alongside that, built Insighta Labs solo: a demographic-intelligence API with dual OAuth and a rule-based natural-language query parser.

  • Led both backend and frontend delivery. 4 backend engineers, 7 frontend, while remaining the top individual contributor on the frontend myself.
  • Owned database design across the entire team; every engineer extended schemas I originally built, keeping the data layer consistent as the team scaled.
  • Built the prompt-to-manifest generation pipeline and its event-publishing layer. The path that turns a user's prompt into a set of customized AI-agent manifest files. 30+ manifests generated in production use.
  • Owned all frontend-to-API integration and built several of the marketing pages.

Contract

Backend DeveloperJul 2025 to Jan 2026

Task-based gaming platform with real-money payouts. Four distinct user roles (regular, VIP, business, influencer), strict permission boundaries, and abuse-prevention logic that had to survive both ephemeral and long-lived tasks.

  • Designed the abuse-prevention layer: a hybrid Redis-TTL + join-table storage strategy that prevented reward farming across task resets, regardless of whether tasks were short-lived or non-expiring.
  • Built the webhook layer linking third-party game outcomes to internal payouts. Game ends, condition checks, reward fires, all idempotent.
  • Co-designed core schemas (user, task, reward, role) and the permission system that enforces what each user type can see and do.
  • Moved heavy operations onto Celery workers behind Redis. User-facing endpoints stopped paying for image processing and external API roundtrips.

Contract

Backend EngineerDec 2024 to Jul 2025

Multi-service food commerce platform connecting vendors, suppliers, and delivery operations. I owned the Supplier service end to end and stepped in as acting lead when the engineering lead left.

  • Designed and led the Supplier service from scratch: supplier lifecycle with four explicit states (pending, approved, rejected, suspended), full audit logging, and admin tooling. 500+ suppliers, ~50 products each at pilot.
  • Acted as backend lead for 8 weeks across a 7-engineer team. Reviewed architecture decisions, unblocked contributors, kept shipping. Also designed scoped JWT for safer service-to-service calls.
  • Refactored bare-except blocks and swallowed exceptions into structured error handling with consistent response shapes and full logging. Silent failures became traceable, on-call became less painful.
  • Reviewed PRs across all three backend services (Supplier, Delivery, Kitchens), keeping conventions consistent across an evolving codebase.

HNG Internship, Sitelytics

Internship

Backend EngineerOct 2025 to Dec 2025

Finalist in a globally competitive engineering internship, contributing to Sitelytics, a website analysis platform for non-technical users. Selected among ~309 finalists from 22,000+ interns.

  • Built the Admin system from scratch as sole contributor: role-based access control, user monitoring, scan tracking, admin-managed content.
  • Built the platform notification system end to end (retrieval, deletion, email delivery) and the helper utilities that standardized notifications across services, removing the inconsistent handling that existed before.
  • Contributed to the async website-scanning pipeline using background workers and Server-Sent Events for real-time scan progress in the UI.
  • Reviewed code across a 15-engineer backend team; held the bar on consistency during fast iteration. Acted as temp team lead for one sprint.

Let's build something that has to work.

I'm open to backend engineering roles. Production systems, APIs, and data pipelines that have to stay up. A good conversation about systems works too.
