Hello! I’m a hands-on Technical Lead and Senior Full-Stack Engineer with 15+ years of experience building, scaling, and operating AI-powered products, SaaS platforms, data pipelines, and cloud infrastructure. I combine architecture and technical leadership with direct implementation. I work inside the codebase, make practical technical decisions, solve production problems, improve infrastructure, and deliver reliable software from idea to deployment. My focus is not simply adding an AI API to a product. I design complete workflows around AI, data, automation, validation, monitoring, security, and business outcomes. What I can help you with AI-powered SaaS architecture and full-stack development LLM integrations using OpenAI, Gemini, Qwen, Ollama, structured outputs, embeddings, and RAG Document, CV, and structured-data extraction pipelines AI-assisted scoring, matching, recommendations, and workflow automation Backend APIs, microservices, queues, concurrent workers, and event-driven systems React, Next.js, React Native, Node.js, Python, PHP, and Go development PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, and vector search AWS, OVH, Docker, Kubernetes, CI/CD, monitoring, and production operations Technical audits, performance optimization, cloud migration, and infrastructure cost reduction Relevant experience I have delivered production systems across recruitment technology, HR platforms, enterprise SaaS, AI search, automation, mobile applications, and large-scale data processing. Recent work includes: AI-assisted CV parsing and structured candidate-data extraction Candidate scoring, matching, assessments, and recruitment automation RAG and semantic-search workflows Multi-provider AI integrations Python-based data-processing and normalization pipelines High-performance Go services and concurrent workers React, Next.js, and React Native applications Docker and Kubernetes-based deployments CI/CD with GitHub Actions, GitLab CI, Bitbucket Pipelines, and Jenkins Monitoring and observability with Grafana, OpenSearch, Filebeat, and Metricbeat I also led the migration of high-traffic production systems from AWS to OVH, reducing infrastructure costs by approximately 40–70% while improving performance and operational reliability. I have experience as a CTO and Team Lead, but I am not looking for a management-only position. I prefer hands-on technical leadership: architecture, implementation, code reviews, DevOps, troubleshooting, mentoring, and shipping production software. I communicate clearly, take ownership, and focus on solutions that are scalable, maintainable, secure, and commercially practical.
