You will get your backend bugs, database bottlenecks, or API errors FIXED
Project details
Broken code is costing your business money, time, and sanity.
When a critical API fails, a webhook drops, or a database query stalls out under load, your users don't care how beautiful your application layout looks, they just know it doesn't work.
I look at software through a rigorous systems-engineering lens. As a First-Class Mechanical Engineering graduate turned Backend Architect, I track down system anomalies with mathematical precision. I specialize in diving deep into existing codebases to isolate runtime errors, clean up architectural bottlenecks, and safely optimize performance without introducing regression bugs.
HOW I STABILIZE YOUR SYSTEM:
• Precision Debugging: I analyze your server error logs to trace, isolate, and completely resolve the root cause of crashes.
• Performance Profiling: If your system is running slow, I pinpoint the heavy database loops or synchronous locks holding it back.
• Code Refactoring: I transform fragile, messy scripts into clean, modular, and secure backend code that is easy to maintain.
No matter if your system runs on Go, TypeScript, or Python, let’s get it fixed properly. Click "Invite to Job" and let's restore your peace of mind!

About Osazuwa Matthew
Backend Engineer | Go (Golang) | TypeScript | Python | Js Architecture

What you really want is a system that works exactly the way you think it should; whether that means launching a fresh product without bugs, debugging coding issues, freeing your team from manual data tasks, or keeping your servers alive during a traffic spike.
Software development often feels unnecessarily complicated, full of jargon, and prone to breaking when you need it most. If you are building a new product from scratch, a wrong turn in the foundation can lead to a costly rewrite later. If you are trying to automate a daily workflow, a fragile script will just end up creating more manual work for you to fix.
I bridge that gap by looking at software through a physical engineering lens. As a First-Class Mechanical Engineering graduate turned Backend Architect, I design digital infrastructure with the same mathematical precision used to build physical machines.
Whether we need to write a low-latency Go API for a fast-growing application, build a type-safe TypeScript backend for a new SaaS product, or hook up a custom Python pipeline to automate your daily business workflows, I build systems to be quiet, predictable, and resilient.
Here is how we can collaborate to solve your current challenge:
REWRITING PROBLEMS INTO SOLUTIONS
• Building from Scratch? I will design a clean, modular foundation using Domain-Driven Design (DDD). This means your product launches smoothly, and as you grow, new features can be added like Lego blocks without breaking the old ones.
• Automating Daily Operations? We will eliminate human error by hooking up smart data pipelines, web scrapers, or AI integrations (like Mastra and LLMs) that run silently in the background, giving your team their hours back.
• Scaling Up or Optimizing? We will find the bottlenecks. I specialize in taking slow, struggling Python or JS setups and rebuilding them into highly concurrent, lightning-fast Go services.
EVIDENCE FROM THE WORKSPACE
• Parallel Kinematic Optimization Engine (Go + React): I engineered a parallel computational grid that handles intense, high-speed vector position math using Go’s native concurrency tools (goroutines and channels).
• Multi-Tenant Notification Engine (TypeScript + Redis + BullMQ): I architected an event-driven microservice implementing the Strategy Pattern to route high-volume webhooks reliably across multiple third-party platforms.
• Academic Core: Graduated with First-Class Honors in Mechanical Engineering, specializing in computational systems, advanced kinematics, and fluid logistics.
THE TOOLKIT I USE:
• Languages: Go (Golang), TypeScript, Python, JavaScript (ES6+).
• Frameworks & Ecosystems: Node.js, Express, Django, FastAPI, Mastra, Git/GitHub.
• Databases & Infrastructure: PostgreSQL, MySQL, MongoDB, Redis caching, Linux/Ubuntu server environments.
You shouldn't have to spend your days babysitting your software infrastructure or worrying about system downtime.
Let’s jump on a brief alignment call to map out your project goals, look at the tools you want to connect, and sketch out the right blueprint for your system.

Steps for completing your project
After purchasing the project, send requirements so Osazuwa Matthew can start the project.
Delivery time starts when Osazuwa Matthew receives requirements from you.
Osazuwa Matthew works on your project following the steps below.
Revisions may occur after the delivery date.
Log Analysis & Root Cause Isolation
We review your active server error logs, crash signatures, or execution bottlenecks. I trace the bug back to its absolute point of origin in the codebase or database schema, ensuring we aren't just placing a band-aid over a deeper problem.
Targeted Refactoring & Bug Resolution
I implement the precise code modification or configuration tune required to fix the error across your Go, TypeScript, or Python setup. All fixes are engineered cleanly to optimize execution and avoid introducing regression bugs.
