Senior Full-Stack Developer · DevOpst Python/PHP/Java Engineer

I’m a Senior Full-Stack Developer with over 6 years of experience shipping production web platforms using Python/Django (or Flask), PHP/Laravel, Java/Spring Boot, and Node.js on the backend, along with React, JavaScript, TypeScript, and HTML/HTMX on the frontend. I also develop mobile applications using Flutter and manage the Linux infrastructure that supports these systems. Coming from a Business Administration background, I focus on building software tailored to how companies actually operate, ensuring tools fit the needs of managers, accountants, sales representatives, and end customers rather than generic CRUD pages.

Currently, I lead full-stack development and DevOps for a SaaS lead-generation platform at VocalEdge Solutions SRL. I own the entire stack end to end—from PostgreSQL/ClickHouse data modeling and designing a proprietary lead-scoring large language model (LLM) that I trained from scratch, to managing the VoIP call stack and the servers, DNS, and security infrastructure. I am committed to continuous learning and staying up to date with technological advancements.

My experience includes building a proprietary lead-scoring LLM from zero, handling data labeling, model training, serving, prompt safety, and evaluation. I integrate multiple data enrichment and scoring signals from various sources to produce a confidence score that drives routing, buyer matching, and pricing decisions. I also manage VoIP and call infrastructure, including providers like Convoso, VICIdial, CloudTalk, and Twilio Voice, and orchestrate real-time call flows with custom backends.

I have integrated AI calling agents to autonomously handle client outreach while ensuring compliance and CRM handoff. I maintain phone-number monitoring and DNC remediation to comply with TCPA and federal/state regulations. My DevOps responsibilities include Linux server hardening, managing Nginx, PostgreSQL, ClickHouse, Docker, automated backups, and zero-downtime releases. I also manage DNS records, SSL/TLS certificates, firewalls, and fail2ban.

Previously, I ran a freelance practice delivering over 30 production web platforms for small businesses, NGOs, and brands, handling everything from requirements gathering to deployment and long-term support. I have also completed a web development internship contributing to production projects in an Agile team environment. My technical skills span backend, frontend, mobile, blockchain, databases, DevOps, networking, cloud hosting, telephony, compliance, AI/ML, integrations, security, SEO, and tooling.
