Salesforce Architect and Agentforce + AI specialist. I help SaaS and growing SMBs migrate, clean up, and scale Salesforce, then layer AI agents and MCP on top. 9+ years, 100% JSS, Top Rated on Upwork. Most Salesforce consultants implement what you ask for. I fix what's actually broken and build what actually scales. 𝗥𝗲𝗰𝗲𝗻𝘁 𝘄𝗼𝗿𝗸 (𝗹𝗮𝘀𝘁 𝟲 𝗺𝗼𝗻𝘁𝗵𝘀): • Built a custom enterprise-grade MCP server for Salesforce with its own UI. Works with both Claude and ChatGPT custom MCP connectors. • Shipped Claude AI workflows wired directly into Salesforce on the Rethink+ project. • Connected Salesforce with Slack, Outlook, Dropbox, and Smartsheet through MCP. • Designed AI-driven Sales and Service agent workflows using Agentforce + Claude. • Engineered a multi-MCP AI desk (Excalidraw, Google Stitch, Serena, Slack, ClickUp), documented publicly on Medium. 𝗖𝗲𝗿𝘁𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: Anthropic Claude MCP (Advanced Topics), Anthropic Claude Code, Salesforce Agentforce Specialist, Copado AI & Robotic Testing. 𝗪𝗵𝗲𝗿𝗲 𝗜 𝗵𝗲𝗹𝗽 𝗺𝗼𝘀𝘁: • Salesforce migrations (legacy CRM to Salesforce, org-to-org, Classic to Lightning) with minimal downtime and a real rollback plan • Org cleanup and scalable architecture, fixing over-customised, slow, or broken setups • Agentforce Sales Agent and Service Agent implementation • Claude AI + Salesforce integrations (custom actions, flows, APIs) • Custom MCP server builds, enterprise-grade, UI-ready, LLM-agnostic • Multi-system integration across Slack, Outlook, Dropbox, Smartsheet, and custom APIs • Advanced Flow automation, AI-driven routing, decision systems • Data Cloud and real-time data sync 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸: Understand the business problem first, not just the ticket. Design the architecture before writing a single line. Build with security and documentation baked in. Hand it over so your team actually owns it. 𝗖𝗼𝗺𝗺𝗼𝗻 𝘄𝗮𝘆𝘀 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘀𝘁𝗮𝗿𝘁 𝘄𝗶𝘁𝗵 𝗺𝗲: • MCP feasibility review or custom MCP server build • Agentforce Sales or Service Agent implementation • Salesforce migration assessment and readiness review • Org health check and architecture review • Fixing one broken automation or integration 𝗖𝗼𝗿𝗲 𝘀𝘁𝗮𝗰𝗸: Salesforce (Sales Cloud, Service Cloud, Data Cloud, Flow, Apex, APIs), Agentforce, Claude AI, MCP (Model Context Protocol), Copado, Slack, Outlook, Dropbox, Smartsheet, ChatGPT custom connectors. If you're migrating Salesforce, cleaning up a messy org, or building real AI agents on Agentforce or Claude, send me your current challenge. I'll be honest about whether I'm the right fit and what it would actually take to solve it.

I'm a Principal Engineer with 20+ years building enterprise systems that stay up, now focused on production AI: AI agents, LLM applications, and RAG. I ship agentic workflows, retrieval pipelines, and LLM integrations on rock-solid Java + AWS foundations — engineered with the rigor to survive real load, real users, and real scrutiny, not just impress in a proof-of-concept. ⚡ AI Agents · LLM Apps · RAG · MCP · Java · Spring Boot · Kafka · AWS PLATFORM ENGINEERING & ARCHITECTURE ▸ Backend & distributed systems — Java/Kotlin (Spring Boot) as the core, plus Python (FastAPI). Event-driven microservices, Kafka pipelines, REST and GraphQL APIs, PostgreSQL. Systems designed to scale, fail gracefully, and pass security review. ▸ Cloud & platform engineering — AWS, Docker, Kubernetes, Terraform, CI/CD. Reusable platform patterns adopted across multiple teams. ▸ Technical leadership — 20+ years leading architecture and hands-on delivery; guided teams from 10 to 55+ engineers across multiple time zones. AI, LLM & AUTOMATION ▸ AI agents & agentic workflows — multi-step agents with LangChain and LangGraph. Tool calling, structured outputs, error recovery, and MCP (Model Context Protocol) servers that expose your tools and data to LLMs cleanly. Agents that complete real tasks, not chatbots that loop. ▸ Production RAG — hybrid search (BM25 + semantic), vector databases (pgvector, Pinecone, Weaviate, OpenSearch), grounding guardrails and evaluation so your AI cites real sources, not hallucinations. ▸ LLM integration — AWS Bedrock, Anthropic Claude, OpenAI. Prompt versioning, JSON-schema enforcement, and CI/CD regression evals so prompts do not silently break when you ship. ▸ AI automation — wiring LLMs and agents into existing business systems to remove manual work, with auditable, deterministic results. END-TO-END DELIVERY ▸ The platform and the product around it — my core is backend and platform (Java, Kafka, AWS) plus the AI running on it, and I take it all the way to a working product with React/Next.js when a project needs it. One senior engineer who owns the platform, the AI, and the deployment — no coordinating between a backend dev, an AI engineer, and a DevOps engineer. WHAT YOU GET WORKING WITH ME ▸ Real production delivery — monitoring, evaluation, and guardrails. Not notebooks. Not demos. ▸ Engineering judgment from 20+ years of distributed systems — whether the job is a Java platform, an AWS build-out, or an AI agent, it sits on infrastructure designed to scale and pass security review. ▸ Regulated-environment fluency — PII handling, audit trails, compliance constraints, and security review are familiar territory (financial-services background), not new problems to solve on your project. PROJECTS I DELIVER WELL ▸ Designing and building scalable backends, APIs, and event-driven platforms ▸ AWS architecture, cloud migration, and infrastructure-as-code ▸ Turning an AI prototype or proof-of-concept into a real production system ▸ Building LLM agents, RAG search, and document extraction into existing applications ▸ AI automation of manual business workflows ▸ Building for regulated industries (finance, healthcare, legal) with compliance built in CORE STACK Languages & Backend · Java · Kotlin · Spring Boot · Python · FastAPI · Node.js · TypeScript · REST · GraphQL · Microservices · Apache Kafka · Event-Driven Architecture Cloud & Platform · AWS · AWS Bedrock · Kubernetes · Docker · Terraform · CI/CD AI & LLM · LLMs · RAG · LangChain · LangGraph · MCP · AI Agents · OpenAI · Anthropic Claude · Vector Databases (pgvector · Pinecone · Weaviate · OpenSearch) · Prompt Engineering · LLM Evaluation Frontend · React · Next.js · TypeScript · Tailwind CSS Data · PostgreSQL · MongoDB · Redis · pgvector HOW WE START Send me a short message describing your project. I respond within a few hours during business days. If it looks like a good fit, we book a free 20-minute scoping call where I give you an honest read on feasibility, approach, and timeline — whether you hire me or not.

Middleware & SaaS Integration Developer: Webhooks, Stripe, Invoicing, SQL. Experienced Control Systems Engineer with 15+ years in industrial automation. Skilled in PLC (Schneider, Siemens), SCADA, SQL, and Python integration. Strong background in Modbus/OPC connectivity and building reliable system solutions. In addition to OT/industrial work, I design and deliver production-grade middleware that synchronizes data between cloud platforms using APIs and webhooks. Typical use cases include invoice generation, two-way status sync, Stripe webhook processing, controlled refund workflows via the Stripe Refund API (with human approval), and a SQL-backed “sync state” layer (ID mapping, event journal, idempotency, retries, audit trails). The goal is always the same: stable automation without breaking existing payment or operational flows. I also deliver enterprise-grade Seagull BarTender Enterprise solutions: designing production-ready .btw labels, integrating with SQL/ERP via ODBC and stored procedures, and deploying automated print workflows at scale. Using Integration Builder (REST/webhooks, TCP, file/queue triggers), Librarian (versioning/approvals), Administration Console and Print Portal (centralized deployment/permissions), and History Explorer/System Database (audit trails, reprints, enterprise-wide archiving), I build robust, compliant labeling systems suitable for multi-site operations. For ERP/WMS-driven environments, I implement BarTender REST API integrations (JSON/YAML over HTTP or HTTPS, Windows/Basic auth, IIS+Print Portal setup), enabling external systems to trigger on-demand label printing directly without file-based intermediaries--complementing Integration Builder for scenarios where the calling system already speaks REST. Core stack: Schneider Modicon (M2xx/M340/M580), Siemens TIA Portal (v20), HMI (Schneider Magelis/Harmony with Vijeo Designer; Siemens KTP/TP series in TIA), SCADA, OPC UA/DA, Modbus RTU/TCP, CANopen, SQL Server, Python (FastAPI/Flask/pyodbc), Windows & Linux deployment (NSSM, services, nginx). Labeling & enterprise printing: Seagull BarTender Enterprise (Integration Builder, Librarian, Administration Console, Print Portal, History Explorer/System DB), SQL/ODBC, ERP/OPC/REST bridges, automated print and archival at scale.
