Full-Stack Engineer · AI Architect · Automation Platform Builder · Strategic Technical Partner Traceable delivery of. 50+ production systems shipped. 100% on-time record. I'm not a freelancer you hire to write tickets, I'm the technical partner who maps the system, owns the architecture, ships the product, and stays accountable through launch, scale, and everything that comes after. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✦ WHAT I BUILD ◆ Full-Stack Web Platforms Next.js · React · TypeScript · Node.js · NestJS · FastAPI · Golang · Java Spring Boot REST, GraphQL, gRPC. Single and multi-tenant SaaS, CRM, ERP, LMS, marketplace, portal — architected for scale before you need it. ◆ Mobile & Desktop Apps React Native · Flutter · Kotlin · Swift · Electron Cross-platform builds that don't trade architecture for speed-to-market. ◆ AI Systems Built for Production Advanced RAG pipelines · Autonomous AI agents · Multi-agent orchestration (LangGraph, CrewAI) · MCP integrations · Voice AI (Vapi, Twilio, Deepgram) · OCR · Computer vision · Model fine-tuning · Real-time inference Built with deterministic orchestration and hallucination controls — not just a wrapper around an API. ◆ Workflow & Business Automation n8n · Make · Zapier · Custom pipeline architecture End-to-end process automation, CRM connectivity, webhook systems, and API integrations that eliminate manual work permanently — not temporarily. ◆ Data Architecture & Backend Systems PostgreSQL · pgvector · Supabase · Redis · BullMQ · MongoDB ETL/ELT pipelines, semantic search, audit-ready reporting. Designed to hold up under real conditions. ◆ Cloud Infrastructure & DevOps AWS · Azure · GCP · Kubernetes · Docker · CI/CD · IaC Serverless, multi-cloud, hybrid, on-prem. Full observability, monitoring, alerting, and centralized logging baked in from day one. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✦ YOU'LL KNOW WE'RE A FIT IF YOU'RE THINKING › "I need an MVP built right the first time — not refactored six months after launch." › "The product has traction. I need someone who can scale it without breaking what works." › "Our no-code stack is becoming the bottleneck, not the solution." › "I want AI properly integrated into the product — not bolted on as an afterthought." › "We operate in a regulated industry and I need someone who actually understands compliance." › "We have manual processes eating 20+ hours a week that should already be automated." ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✦ HOW I WORK 01 No code gets written until the system is mapped. Every engagement starts with functional architecture — where data enters, transforms, and exits; where tasks repeat and can be automated; where load breaks things at 10× current scale. 02 I design for maintainability, reliability, scalability, observability, tenant isolation, and cost-aware infrastructure from the start. Retrofitting these later is expensive. I've seen what that costs. I don't let it happen. 03 For AI systems, hallucination control, deterministic orchestration, evaluation layers, and fallback handling are part of the system design — not afterthoughts. Safe AI in production requires architecture, not just prompt engineering. 04 Most developers finish 80% and call it done. I focus hardest on the last 20% — the edge cases, failure modes, load behavior, and details no one asked for but everyone notices. That's where the real product lives. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✦ STACK Frontend & Mobile Next.js · React · TypeScript · React Native · Flutter · Kotlin · Swift · Electron Backend & APIs Node.js · NestJS · Python · FastAPI · Golang · Java Spring Boot · REST · GraphQL · gRPC · WebSockets AI & Automation LangGraph · LangChain · CrewAI · AutoGen · DSPy · MCP OpenAI · Claude · Gemini · Llama · Mistral · Groq RAG Pipelines · pgvector · Pinecone · Qdrant · Weaviate · Chroma Vapi · Twilio · Deepgram · ElevenLabs n8n · Make · Zapier · Custom automation pipelines Computer Vision · OCR · Model Fine-Tuning · Voice AI Data & Infrastructure PostgreSQL · pgvector · Redis · Supabase · BullMQ · MongoDB AWS · Azure · GCP · Kubernetes · Docker · CI/CD · IaC · Observability Compliance & Security HIPAA · SOC2 · PCI-DSS · HL7/FHIR OAuth2 · JWT · RBAC · ABAC · Audit Logs · KYC/AML ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✦ INDUSTRIES HealthTech / EMR / EHR / FHIR · FinTech / Payments / KYC · LegalTech · InsurTech B2B SaaS · eCommerce · Marketplaces · PropTech Logistics & Supply Chain · ConstructionTech · AI-Native Products · Web3 / Blockchain ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝙄𝙛 𝙮𝙤𝙪'𝙧𝙚 𝙗𝙪𝙞𝙡𝙙𝙞𝙣𝙜 𝙨𝙤𝙢𝙚𝙩𝙝𝙞𝙣𝙜 𝙧𝙚𝙖𝙡, 𝙨𝙘𝙖𝙡𝙞𝙣𝙜 𝙨𝙤𝙢𝙚𝙩𝙝𝙞𝙣𝙜 𝙩𝙝𝙖𝙩'𝙨 𝙛𝙤𝙪𝙣𝙙 𝙩𝙧𝙖𝙘𝙩𝙞𝙤𝙣, 𝙤𝙧 𝙛𝙞𝙭𝙞𝙣𝙜 𝙨𝙤𝙢𝙚𝙩𝙝𝙞𝙣𝙜 𝙩𝙝𝙖𝙩'𝙨 𝙨𝙩𝙖𝙧𝙩𝙞𝙣𝙜 𝙩𝙤 𝙘𝙧𝙖𝙘𝙠.
