Hire the Best Embedded Systems Engineers in Massachusetts

Here’s the short version: I ship, and I can prove it twice. Proof one is public — 3,200+ hours here, 100% job success, Top Rated Plus, and a decade of production web applications behind it. Proof two is in my portfolio. In July I built the long-term memory subsystem for a fully offline AI assistant: a graph memory store, a nightly consolidation pipeline, adversarial entity deduplication, a retrieval head. Solo — architecture, ML, and evaluation. Every headline number in that write-up has a measurement under it, because that’s the only way to know if a system like this actually works. One of those tells you I’ll finish. The other tells you what I can build. Go read the second one — it’s the fastest way to find out if I’m your guy. The long version: I build ML systems and automation for problems that don't have clean documentation or off-the-shelf answers. If your project lives somewhere between software engineering, data, and "why is this harder than it should be," I'm probably a good fit. I'm a systems-minded engineer with a background spanning applied machine learning, simulation modeling, web applications, and integrations. I focus on building working, testable tools, not demos that fall apart when real data shows up. Recent / relevant experience: • Designed and built the long-term memory subsystem for a fully offline LLM voice assistant — graph memory substrate, nightly consolidation pipeline, adversarial entity deduplication, retrieval head. Solo: architecture, ML, and evaluation. • Local LLM deployment on constrained hardware — quantized 14B inference, RWKV, Whisper STT, containerized services over a message bus • Built production systems using Python, Ruby on Rails, React, Docker, and Postgres • Designed custom data pipelines and integrations across messy, undocumented APIs (including Shopify) • Meritorious Winner, COMAP ICM — stochastic simulation of kidney donor networks I'm especially strong at taking loosely defined ideas and turning them into clear, reliable systems with visible progress early in the project. I work best with clients who value clear scope, early deliverables, and honest communication. Bonus points if your project description includes the phrase "we thought this would be simpler." 🔍 Current focus ML systems work — specifically memory, retrieval, and evaluation for language models running in real constraints. Solid math background, strong engineering instincts, and the discipline to measure whether a system actually works rather than assume it does. I'm most useful when AI is part of a larger system, where the hard problems are architecture and evaluation rather than model training. Core stack: Python, JavaScript, SQL ML / LLM: llama.cpp, Qwen, RWKV, Whisper, embeddings, vector search, RAG, knowledge graphs, PyTorch, OpenAI APIs Infrastructure: Docker, NATS, FastAPI, Postgres, SQLite, CUDA Web: React, Rails Additional experience: C/C++, Java, PHP, Matlab, R, embedded systems, legacy platforms

Most businesses lose customers they never even knew they had - a lead that came in after hours, a call that went to voicemail, a follow-up that never got sent. I build the systems that fix that. Whether you're a coach booking discovery calls or a home-service business trying to catch every lead while you're out on a job, I set up AI booking, automated follow-up, and clean CRM systems so your leads get answered in seconds and nothing slips through the cracks. What I build: - AI appointment setting (chat + phone) that qualifies leads and books them 24/7 - Missed-call text-back, so an unanswered call becomes a booked job instead of a lost one - Automated 5-star review generation to build the reputation local customers check first - GoHighLevel funnels, pipelines, and email/SMS follow-up that nurture leads until they buy - Conversion-focused websites wired to your CRM so every enquiry is captured - Automation (Make, n8n, Zapier) that connects your tools so the busywork runs itself Who I work with: - Coaches & consultants - onboarding, nurture, and booking systems so you spend your time coaching, not chasing admin - Local service businesses (home services, health & wellness, and more) - never miss a lead, fill your calendar, and stack up 5-star reviews Why me: I don't hand you a tool and disappear. I map out where you're actually leaking leads, build something clean that a non-technical person can run, and document it so it keeps working. Many clients keep me on a monthly retainer to run and optimize it for them. Tell me what's slowing you down and I'll tell you honestly whether I can help.

I have 10+ years of experience building end-to-end dashboards, marketing analytics platforms, and data warehouses for organizations ranging from startups to publicly traded enterprises like Wayfair, as well as government organizations such as the Commonwealth of Massachusetts. I have held senior roles such as Head of Data and Enterprise Data Architect, and my background in software engineering allows me to build analytics systems that go far beyond basic dashboards, with clean data pipelines, reliable attribution, and automated reporting. I can help you consolidate data from multiple platforms (ad networks, analytics tools, e-commerce systems, CRMs) into a single, reliable source of truth. Whether you need cross-channel attribution, blended ROAS and CAC calculations, white-labeled client reporting, or a scalable data warehouse foundation, I can build and maintain the infrastructure that makes clean reporting automatic instead of a weekly time sink. Here, you can check out a few of my case studies: I helped Wayfair's Marketing Engineering team develop a comprehensive cross-channel attribution model that unified data from paid search, display, email, social media, and content marketing. The project involved implementing server-side tracking, building ML-powered attribution models, and creating dashboards that visualized the complete customer journey. The result was a 16% increase in ROAS and multiple 8-figures in additional revenue through optimized ad spend and improved customer targeting. I helped Kum&Go, a retail company with 430 stores and nearly 500K loyalty subscribers, implement RFM segmentation using machine learning. The project involved collecting and normalizing customer data, building K-means clustering models, and creating actionable customer segments for targeted marketing campaigns. The results included an 18% increase in email open rates and click-through rates, along with a 16% increase in customer lifetime value. I also support marketing agencies with white-labeled dashboard solutions that pull live data from their clients' ad accounts, eliminating the manual spreadsheet exports and screenshot reports that consume hours every week. My approach saves their respective teams 5-10 hours every week on reporting, and ensures the numbers are always consistent and trustworthy. I can extract and normalize data from virtually any source, including ad platforms, e-commerce systems, email marketing tools, CRMs and more. When it comes to building dashboards, I have extensive experience with the following technologies: Analytics and CRM: GA4, HubSpot, Klaviyo, Salesforce, ActiveCampaign Data Warehouses: BigQuery, Snowflake, Amazon Redshift, PostgreSQL, ClickHouse Data Visualization: Power BI, Looker Studio, Tableau, Data Studio, Metabase, Superset Thanks for taking the time to read this. If you think we might be a good fit, feel free to send me a message here on Upwork. Looking forward to connecting with you!
