Disconnected tools and manual processes are costing you more than you think ๐
Every missed follow-up, broken handoff, and hour spent copy-pasting between systems is revenue you're never getting back. I build AI automation systems that eliminate those gaps - end-to-end, documented, and built to scale without a developer babysitting them.
What I deliver
๐งฉ Lead qualification & routing systems - AI that scores inbound leads, enriches with company data, and routes hot prospects to your reps in seconds instead of hours.
๐งฉ AI-powered outbound systems - multi-step prospecting sequences with personalized research and outreach at scale, so your team books meetings instead of writing copy.
๐งฉ Pipeline automation - deal stage transitions trigger follow-ups, Slack briefings for managers, and clean handoffs to CS so nothing falls through the cracks.
๐งฉ AI sales agents with human-in-the-loop - autonomous agents that qualify inbound leads, research accounts, draft replies, and book meetings, with approval gates where it matters.
๐งฉ RevOps reporting & intelligence - pipeline health dashboards, at-risk deal flagging, and weekly forecasts that actually help leadership make decisions.
Why my background matters
๐ I've spent years inside B2B SaaS as a Senior Sales & Solutions Engineer, working alongside revenue teams scaling from $5M to $100M+ ARR. I've seen exactly how RevOps gaps cost real revenue - slow follow-ups, broken pipeline data, and manual handoffs that lose deals. That's why I build systems differently from freelancers who've never sat in a sales seat.
โ๏ธ I architect for what actually breaks in production: scale, reliability, governance, edge cases. Not for what looks good in a demo.
Certified n8n Expert Partner & Make Gold Partner - specialized in scalable automation for B2B sales, marketing, and operations teams.
AI is becoming invisible infrastructure - like electricity became for industry. Teams that weave it into every process now build a compounding lead; laggards pay the tax later.
How I work:
Discovery call (30 min) - I learn your stack, your team, and what's actually broken vs. what just feels broken.
โ
System architecture - I map your current workflow on one page: where data lives, where it leaks, and what needs to change. You see the plan before any code is written.
โ
Phased build - milestones with weekly demos, fixed pricing on each phase, and full documentation so your team owns what we ship.
โ
Optional retainer - most clients keep me on for ongoing system expansion after the first project
How I think about the work
โ Reliability over novelty. Your system has to run on a Tuesday morning when nobody's watching. Boring is beautiful at scale.
โ Outcomes over hours. I measure success in deals saved, hours returned to your reps, and pipeline accuracy - not in tickets closed.
โ Documentation is part of the build. Every system ships with SOPs and Loom walkthroughs. Your team owns and operates everything we build.
โ Owner mindset. I treat your roadmap like equity. If something shouldn't be built, I'll tell you. If something cheaper exists, I'll recommend it.
Stack
CRM: HubSpot, Pipedrive, Salesforce
Automation: n8n, Make, Zapier, Apps Script, Python/Node
AI: Claude, OpenAI, LangChain, RAG with Pinecone/Supabase
Outbound & enrichment: Apollo, Clay, Instantly, Smartlead
Voice & messaging: VAPI, Retell, Twilio, ElevenLabs
Ops & reporting: Airtable, Notion, Slack, Looker, Google Sheets
๐ Letโs jump on the quick Upwork Call.
Tell me whatโs on your shoulders - tasks, delays, or failure points you want gone.
Iโll sketch the fastest path to relief, outline a lean pilot, and quote milestones - so we move quickly, and you get outcomes, not buzzwords.

If youโre looking for more than just a 3D concept โ if you need real, functional product designs built for manufacturing, prototyping, and actual use โ I can help.
Iโm a U.S.-based mechanical/product engineer with over 15 years of CAD design experience and a proven track record of bringing physical products to life. My designs arenโt just for show โ theyโve been manufactured, tested, shipped, and used by real customers in real environments.
From precision mechanical assemblies to injection-molded components, 3D-printed prototypes, and production tooling, Iโve delivered complete solutions for clients ranging from startups to major manufacturers. Iโve worked as a Senior Product Engineer at a publicly traded company, contributed to government and defense programs, and designed parts for industries including 3D printing, firearms, consumer electronics, and industrial automation.

โ Machine vision and AI inspection systems
โ UAV, rover, and robotic platform development
โ 3D CAD design, enclosure design, and 3D printing
โ Manufacturing-ready product development and supplier support
Our approach is simple: we do not just โbuild what is asked.โ We first understand the product goal, technical risk, cost target, user environment, and manufacturing path. Then we design the right engineering solution with the correct balance between performance, budget, timeline, and scalability.
We are especially strong in projects where hardware, software, firmware, mechanics, and real-world testing need to work together. Many product development projects fail because each part is built separately. Idea8 solves this by managing the complete development process from concept to working prototype and beyond.
Core technical capabilities:
โข Embedded systems and microcontroller programming
โข Firmware development using C, C++, Python, and related tools
โข PCB design, schematic design, and electronics integration
โข IoT platforms using ThingsBoard, Blynk, cloud dashboards, and custom web apps

โข 3D printing, rapid prototyping, testing, and product iteration
If you are looking for a team that can think like engineers, execute like product builders, and communicate clearly like a long-term technical partner, Idea8 can help.
We are best suited for clients who need serious engineering execution, not just basic task completion. Whether you are building a new hardware product, improving an existing system, automating a factory process, or developing an IoT/robotics solution, we can support you from the first prototype to a manufacturable product.
Letโs build something real.
