About this gig
Are you looking for a standard boilerplate developer, or an enterprise-grade Software Architect who builds secure, high-performance AI applications and robust SaaS ecosystems?
With over 8 years of engineering expertise, I design decoupled, multi-tenant architectures built to handle heavy production loads and mitigate modern security threats.
What I can engineer for your business:
Advanced AI & Agentic Workflows: Multi-model systems (DeepSeek R1/Gemini Pro) utilizing background workers to safely bypass server timeouts.
Clean Backends & Dashboards: Scalable MVC systems using PHP (8.2+ PDO/Laravel) and FastAPI, paired with dynamic analytics layers (Chart.js) and real-time filtering.
Hardened Security & CDR: Custom Content Disarm & Reconstruction (CDR) pipelines to sanitize file uploads, backed by rigid Cloudflare WAF geo-blocking.
Compliance Storage: Immutable data vaults via S3 Object Lock for legal document retention.
Let's discuss your project constraints before ordering.

FAQ
Do you use standard API integrations, or can you build autonomous AI workflows?
I engineer both. I can implement simple API connections or architect complex, autonomous agentic workflows using models like DeepSeek R1 and Gemini Pro, utilizing asynchronous task queues to ensure long-running AI processes never trigger server timeouts.
Which backend technologies and frameworks do you specialize in?
My core stack for enterprise applications includes PHP 8.2+ (Clean MVC, PDO, and Laravel) and Python (FastAPI). I pair these with robust databases like PostgreSQL and MySQL, leveraging strict indexing and structured JSONB layers for high-frequency data streams.
How do you handle application security and file uploads?
Security is embedded into the architecture. I implement zero-privilege Docker environments, custom Content Disarm and Reconstruction (CDR) pipelines with in-memory scanning to neutralize malware, and advanced Cloudflare WAF configurations to block automated exploits and geo-threats.
Can you sign an NDA before we discuss the project details?
Yes, absolutely. I work with corporate clients and proprietary business logic regularly. We can sign a Non-Disclosure Agreement (NDA) before you share any sensitive repository details, API keys, or functional requirement documents.
