I’m a senior AI systems and full-stack engineer with deep experience designing, building, and shipping production AI products end to end. I specialize in turning complex ideas into reliable, scalable systems that actually work in the real world. My background spans AI/ML pipelines, backend systems, and modern web applications. I’ve led and contributed to projects involving large language models, multimodal analysis (video/audio), RAG architectures, automation pipelines, and subscription-based SaaS platforms. I’ve worked both as a freelancer and as a lead engineer on internal AI products used by real customers at scale. What I do best is bridge the gap between research and production. I don’t just prototype. I design systems that handle edge cases, cost constraints, performance targets, and long-term maintainability. That includes API design, data modeling, infrastructure decisions, and clear handoffs to frontend or product teams. Core strengths: → AI, Agents & LLM Systems: RAG pipelines (LangChain, Pinecone), Model Context Protocol (MCP), OpenAI/Gemini/Whisper, and custom evaluation frameworks. → Backend Engineering: Java Spring Boot, .NET, Python, Ruby on Rails, Node.js, PHP. → Workflow Automation: Complex orchestration using n8n and Zapier to connect AI agents with business logic. Full-Stack Apps: React, Next.js, TypeScript, .NET, Java, PHP, Ruby on Rails, Supabase, Stripe, and secure authentication flows. Data & Infrastructure: Postgres, MySQL, Docker, AWS, and CI/CD pipelines. I’m especially strong in AI products that involve: ✓ Advanced RAG: Retrieving context from complex datasets (PDFs, Databases) for accurate LLM responses. ✓ Multimodal Analysis: Processing Text, Audio, and Video inputs. ✓ Structured Outputs: ensuring JSON reliability and strict evaluation logic. ✓ Cost-Aware Workflows: Optimizing token usage and latency. ✓ Human-in-the-loop Systems: Designing approval flows for critical AI tasks. Clients hire me when they need someone who can think like an engineer, a product owner, and a business operator at the same time. I ask the right questions up front, communicate clearly, and deliver systems that are built to last. If you need help designing a robust RAG system, stabilizing a backend, shipping a full product, or untangling an automation workflow that’s gotten too complex, I can help. Happy to jump on a call and talk through your problem before writing a single line of code.

I’m a seasoned developer with over a decade of hands-on experience in programming and design across PC, mobile apps, and VR platforms.

With a PhD in computational studies and expertise in Unreal Engine, Unity and Javascript/Typescript, I focus on building efficient, scalable systems and creating engaging experiences. I’ve led and contributed to multiple full-cycle game and software projects - from concept and prototyping to launch and post-release optimization. I’m comfortable handling both the technical and creative sides of development and enjoy helping teams turn strong ideas into polished, playable realities. If you’re looking for someone, or a team who can architect, code, and iterate efficiently, let’s connect and build something great together.

I’m a cloud and software developer with a solid background in AWS, Python, and DevOps. I recently graduated from college with a degree in Computer Science, and since then I’ve been focused on building scalable APIs, serverless apps, and automated deployments that are production-ready and easy to maintain. What I bring: Cloud: AWS certified (Solutions Architect & Developer Associate). Hands-on with Lambda, API Gateway, DynamoDB, ECS, and S3. Development: Strong in Python and Java, experienced with Flask for APIs and modern backend development. Machine learning: Knowledge on Tensorflow(neural networks), langchain(agents and RAG). Ability to create models to make predictions based on historic data. DevOps: Skilled with Docker, Terraform, and CI/CD (GitHub Actions, Jenkins). Projects: Delivered serverless backends, event-driven workflows with SQS/EventBridge, and containerized apps running on ECS and Kubernetes. Also REST apis written in flask/django/springboot(java) and several frontends in both React and NextJS. Fluent in English and Spanish, and open to work on both fixed-price and hourly projects.

I help mobile, Unity, and SaaS teams fix complex app issues, integrate native iOS/Android SDKs, connect apps with backend APIs, and deploy production-ready systems on AWS. My strongest area is solving problems that sit between Unity, native mobile, backend APIs, cloud services, and third-party SDKs — the type of work where normal Unity developers often get stuck. I have completed many Upwork contracts involving Unity iOS/Android plugins, in-app purchases, subscriptions, Google Fit, Apple Watch/pedometer integrations, Bluetooth/device integrations, WebView, App Store deployment, Xcode/Gradle build issues, crash fixes, SDK upgrades, and mobile app redeployment. Alongside mobile/Unity work, I also work with Java, Spring Boot, AWS, APIs, databases, CI/CD, Cloudflare/Vercel configurations, and AI API integrations. This allows me to support not only the app side, but also the backend and cloud side of the product. I can help you with: Unity iOS/Android plugin development Native SDK integration for Unity apps IAP, subscriptions, AdMob, push notifications, WebView, Google Fit, HealthKit, Bluetooth, sensors Unity app crash fixing, build errors, Xcode/Gradle issues, App Store/Play Store deployment Backend APIs, Spring Boot, AWS, databases, and cloud deployment AI API integration into existing apps or SaaS products Mobile app backend, authentication, payments, and automation workflows If your project involves Unity, mobile apps, native plugins, backend APIs, AWS, or AI integration, I can help you take it from broken or incomplete to working, deployed, and stable.
