Looking for an engineer who bridges the gap between complex problems and scalable solutions? With over a decade in full-stack development, I specialize in transforming business challenges into high-performance software for healthcare, startups, and consulting clients. My expertise lies in building modern, AI-augmented platforms that drive efficiency and growth. I've developed tools that automate clinical workflows for healthcare providers, built and scaled products from MVP to market fit for startups, and delivered strategic technical solutions for consultancies. My expanded technical toolkit includes: Frontend: React, Next.js, TypeScript, state management (Redux, Context), and modern testing frameworks. Backend: Node.js, Python (Django, FastAPI), REST & GraphQL API design, microservices architecture, and serverless functions. AI/ML Integration: Practical application of LLMs (OpenAI, Anthropic), vector databases, embedding pipelines, predictive model integration, and workflow automation agents. Data & DevOps: PostgreSQL, MongoDB, Redis, data pipeline engineering, AWS (EC2, Lambda, RDS, S3), Azure, Docker, Kubernetes, Terraform, and comprehensive CI/CD (GitHub Actions, GitLab CI). I focus on delivering tangible impact: For Startups: Taking ideas from zero to one by architecting and building the initial MVP, then evolving the technology to support rapid scaling, user growth, and future fundraising. For Healthcare: Building secure, HIPAA-compliant applications and intelligent AI tools that reduce administrative overhead and enhance clinical decision-making. For Consulting: Translating high-level business strategy into concrete, reliable technical execution and architecture. I excel in owning the full product lifecycle, from initial concept and architecture through deployment and iteration, whether leading a team or acting as a hands-on principal engineer. My goal is to cut through complexity and deliver software that directly serves your business objectives. Let's connect to discuss how I can help solve your most critical tech challenge.
