Get started with a free trial before committing! You need a product that works, fast, stable, built to scale and something that the user's really want. Not something your team has to rebuild in six months. That’s what I deliver. I’m a Senior AI & Full-Stack Developer with 5+ years of experience building products from idea to scale, from MVPs to production-ready SaaS platforms. I’ve helped launch startups that ranked #1 on Product Hunt and worked closely with YC alumni founders to turn early concepts into scalable systems used by real customers. Most teams bring me in for a feature. But once we step back and look at the architecture, we usually uncover higher-leverage opportunities, automation, workflow redesign, smarter system decisions, often saving six figures annually in operational costs. I don’t just write code. I partner with teams to build products that ship faster, scale cleanly, and actually work long-term. If you're building or scaling a SaaS product and need someone who thinks beyond tickets, we should talk. ⦿ Industries & Verticals Covered: FinTech, HealthTech, LegalTech, Web3 & DeFi, EdTech, Logistics, Supply Chain, Transportation, E-Commerce, Retail, Manufacturing, Distribution, InsurTech, GovTech, Public Sector, Real Estate, PropTech, Travel, Hospitality, Cybersecurity, Media, Publishing, AI/ML, Data & Analytics ⦿ Products & Platforms Delivered: Multi-Tenant SaaS Platforms, AI-Powered SaaS, Decentralized Applications (dApps), Native & Cross-Platform Mobile Apps, Progressive Web Apps (PWA), Booking & Reservation Systems, AI Tools, Learning Management Systems (LMS), Electronic Health Record Systems (EHR/EMR), Case Management Systems, Inventory & Warehouse Management Systems, ERP Solutions, CRM Systems, Trading Platforms, Marketplaces, Customer Portals, Cloud-Native Applications ⦿ Security, Standards & Compliance: SOC 2, PCI-DSS, HIPAA, GDPR, ISO 27001, NIST (Zero Trust), HL7/FHIR, OAuth2, JWT, RBAC / ABAC, MFA / 2FA, AES-256 Encryption, TLS 1.3, IAM, KMS, Vault, WAF, SAST / DAST, Audit Logging, PII / PHI Protection ⦿ Technology Stack: Front-End Development: React.js, Next.js, Vue.js, Angular, JavaScript, TypeScript, Tailwind CSS, HTML5, jQuery Back-End Development: Golang (Gin, Echo, Fiber, Beego, Revel), Java (Spring Boot), Node.js (Express, NestJS), Python (Django, Flask, FastAPI), Rust, C++, Zig, PHP (Laravel), Ruby on Rails, Elixir, Firebase Mobile Development: React Native, Expo, Flutter, Kotlin, Swift, Electron ⁃ Databases: MySQL, PostgreSQL, MongoDB, AWS RDS ⁃ Messaging & Streaming: Apache Kafka, RabbitMQ, Redis Streams, NATS ⁃ API & Integrations: REST, RESTful APIs, SOAP, GraphQL, gRPC, FastAPI, OpenAPI, WebSockets ⁃ AI & LLM Integration: OpenAI, Claude, Gemini, ChatGPT, Grok, Mistral, LLaMA ⁃ AI/ML & Data Engineering: AI Agents, AI Bots, n8n Automation, TensorFlow, PyTorch, LangChain, LangGraph, DSPy, Apache Spark, Hugging Face, AWS SageMaker, OpenCV, Vertex AI, RAG Pipelines, Fine-Tuning, NLP ⁃ Cloud & DevOps: AWS, GCP, Azure, Linux, VPC, VM, Terraform, Lambda, CloudFront, EC2, ECS, EKS, Fargate, Lightsail, S3, RDS, Kinesis, Kubernetes, Docker, Nginx ⁃ Version Control & CI/CD: Git, GitHub ⦿ Core Expertise & Capabilities: Full-Stack Engineering | Software Development | Web & Mobile Applications | Artificial Intelligence | Machine Learning
