Sublan Mustafa · Senior Full Stack & Lead Architect I architect load-bearing systems products quietly depend on.
6+ years owning solutions end-to-end: Laravel + Vue.js platforms serving millions of users, multi-tenant SaaS fleets, real-time WebSockets engines, and self-hosted AI inference with ONNX Runtime, PyTorch, and Ollama — from database schema design to automated CI/CD on AWS.
Architectures built for scale, uptime & performance
Production systems serving millions of users and enterprise fleets. Every case study outlines the real engineering constraints, architectural decisions, and shipped outcomes.
LogiNXT
Enterprise transportation management platform — vehicle tracking, driver management and violation monitoring — running as multi-tenant SaaS for multiple client fleets.
GuitarTricks.com
Core features and performance work on a large-scale guitar-lesson platform serving millions of active users — under high concurrent traffic.
E-Commerce Platform
A complete e-commerce system built from concept to production — catalog, cart, checkout and order management — powering a web frontend and a companion mobile app from one API.
Real-Time Chat System
Instant messaging on Laravel WebSockets — replacing page-refresh polling with a push-based real-time layer.
Custom Studio Builds & Client Products
End-to-end commercial solutions shipped through my software development studio, Sublanz.
How I design sustainable, load-bearing software
Practical principles refined through 6+ years of building and leading systems that survive production traffic.
Zero-Drift Multi-Tenancy
Serve multiple enterprise client fleets from a single unified codebase. Tenant onboarding becomes a fast configuration task rather than a fragile redeployment.
Push-Over-Poll Event Streams
Retire wasteful database polling. Bi-directional WebSockets push live state instantly to dispatchers, fleet operators, and active users.
Self-Hosted AI Inference First
Deploy open-source LLMs through ONNX Runtime, PyTorch, and Ollama. Own latency, reduce recurring API costs, and guarantee data sovereignty.
Relational Schema Rigor
Clean indexing, structured query plans, and Redis caching. High concurrent challenge traffic requires deep query headroom, not just bigger servers.
Capability matrix anchored in shipped code
No arbitrary percentages or logo clutter. Every technology listed here represents software actively built, maintained, or led in production.
Frontend
6 TechnologiesInterface layer for high-traffic platforms, tuned for rendering performance under concurrency.
Backend
5 TechnologiesAPIs and real-time layers that serve web and mobile from one backend — including payment coverage.
Data
3 TechnologiesRelational modeling, caching and query performance for production systems.
AI / ML Integration
5 TechnologiesOpen-source LLMs and ML models deployed for local, self-hosted inference in production apps.
Infrastructure
3 TechnologiesOwning the path from database design through automated deployment.
Leadership
5 TechnologiesLeading feature teams and setting standards, not just shipping tickets.
Leadership & impact across three engineering teams
Steadily escalating ownership: from full-stack engineer to technical lead responsible for architecture, code quality, and team mentorship.
Senior Full Stack Developer & Technical Lead
- Lead full-stack development of enterprise transportation management systems (including LogiNXT), directing architecture across vehicle tracking, driver management, violation monitoring and multi-tenant SaaS infrastructure.
- Designed a multi-tenancy architecture that reduced per-client deployment overhead and simplified onboarding of new fleet customers.
- Own end-to-end delivery of real-time coaching and chat features built on WebSockets.
- Drive technical direction — code reviews, Laravel/Vue.js standards, mentoring mid-level developers — while prototyping AI-driven driver-coaching with open-source LLMs (Ollama, ONNX Runtime).
Full Stack Laravel & Vue.js Developer
- Contributed core features to GuitarTricks.com, a large-scale platform serving millions of active users.
- Optimized backend queries and frontend rendering to maintain performance under high concurrent traffic during live user challenges.
- Integrated Facebook Graph APIs for website traffic analysis, enabling data-driven marketing decisions.
Laravel & Vue.js Developer
- Built a real-time chat system using Laravel WebSockets, cutting reliance on page-refresh polling.
- Integrated four payment gateways (PayPal, JazzCash, Braintree, Stripe) into a production e-commerce platform.
- Designed and developed RESTful APIs powering the web frontend and companion mobile app, and built a complete e-commerce system from concept to production.
- Recognized as Employee of the Quarter for consistent delivery and reliability; awarded a Punctuality Certificate (2023).

Ownership, standards, and practical AI engineering
I architect and build full-stack products with Laravel and Vue.js — and I take ownership of the whole system, from database design to CI/CD on AWS. Over 6+ years that has meant leading feature teams, setting coding standards, and keeping platforms performing for millions of users, not just passing them off once they ship.
My current interest is practical AI integration: deploying open-source LLMs and ML models through Ollama, ONNX Runtime and PyTorch for self-hosted inference in production applications. I would rather own the inference layer than bolt on a third-party API — it keeps latency, cost and data control on my side of the fence.
The products I enjoy building are operational systems: fleet platforms, commerce engines, real-time tools. Software where the design is measured by whether an operator gets their job done faster — and where performance problems are real, not theoretical.
Currently leading full-stack development of a multi-tenant transportation platform at Wolfiz Solutions, prototyping AI-assisted driver coaching on self-hosted LLMs.
The work here is real. Let's architect your next system.
Whether you need a senior technical lead to steer full-stack architecture, solve high-concurrency scaling bottlenecks, or deliver mission-critical platforms — direct communication starts here.
