I am a senior electronics and embedded systems engineer with 47 years of experience in hardware design, firmware development, PCB layout, debugging, testing, and product development. I help clients turn electronic product ideas, prototypes, and hand-wired circuits into working embedded systems and manufacturable PCB designs. Typical projects I can help with include: * ESP32 and STM32 / STMicroelectronics MCU-based products * Power conversion and low-power battery-powered product design * Custom wireless and RF communications, including LoRa and ESP-NOW peer-to-peer networking * Circuit design and component selection for manufacturing * Schematic entry and multi-layer PCB design. * Ordering fabs and coordinating assembled boards. * C/C++ firmware for sensors, displays, audio, wireless, and control systems * Embedded graphics and touchscreen user interfaces using LVGL * Digital audio filtering, FFT spectrum analysis, and voice activity detection * Cloud API integration for speech-to-text, text-to-speech, and language translation * Embedded bus and peripheral interfaces: I2C, SPI, I2S, UART, RS-485, CAN, and SD/MMC * Prototype debugging and board bring-up * Converting breadboard prototypes into clean PCB designs * Design reviews before manufacturing * Analog and digital circuit troubleshooting * Production-oriented improvements for reliability and manufacturability I have founded and managed engineering companies and consulting firms, led technical teams, and helped bring electronic products from initial concept through prototype, testing, manufacturing, and production. For clients, this means fewer design mistakes, faster debugging, lower development risk, and a clearer path from concept to a working, manufacturable product.

I build functional embedded systems. I have experience working on nuclear inspection robots, underground exploration robots, lunar rovers, tactical military radars, artificial lungs and membrane oxygenator controllers. I have been the technical founder of two startups, and brought a collection of several hardware products to market. Mechanical skills: -CAD modelling (functional, not aesthetic) -3D printing (functional, not aesthetic) -Basic machining Electrical skills: -Circuit and PCB Design (including high-speed) -Wiring technician -Arduino, including custom-arduinos -C, C++, Python, Java (I prefer firmware; I can modify existing firmware, write firmware for pre-existing circuitry, and write firmware for my own circuitry). -General hardware integration Misc: - Technical writing (research papers, grant writing) - Essays (college application essays, fellowship application essays) - College/career advising I have a Master's in Electrical and Computer Engineering from Carnegie Mellon University, specializing in Robotics, and PhD in Biomedical Engineering specializing in medical devices. For Upwork contracts in particular: - I do NOT take contracts that involve recreating existing products for the purpose of saving money (although I will modify existing products to meet additional requirements). Be prepared to answer the question "what unique requirement(s) do you have that prevent you from using existing products" - I need to know why you need something done in order to make the best judgement call. I will keep our interaction private unless you give me permission to publicize it, and can sign a NDA if required. - If you want to hire me for a hour or so of "consulting" rather than actually building something, I would greatly appreciate if you opened a contract rather than "inviting me to interview". It speeds up things greatly. Please mention if you have a background in engineering or industrial design, that makes communicating a bit easier.

I worked on spacecraft systems where failure wasn't an option. I bring that same precision to AI automation that saves you hours and makes you money. I build with Claude Code daily. It's how I architected a multi-agent document extraction system for a $45M manufacturer. Their team was spending hours manually reading 2,000-page spec documents. Now an AI extracts the data, scores each field with confidence ratings linked to source pages, and pushes it into their CRM with one click. Deployed on their infrastructure, used daily, and I'm now building Phase 2: an AI costing engine replacing logic spread across their ERP, spreadsheets, and CAD software. I compressed a 160-hour process for a medtech company down to 5 hours — unlocking an entirely new revenue stream they couldn't scale before. For a real estate investor, I automated their revenue management system for instant ROI and built an AI automation that summarizes property reviews to identify exactly what actions need to be taken at their properties every week — saving them hours and turning scattered feedback into a clear action plan. Built a custom graphic generator for an e-commerce store that produces high-quality merch designs in minutes, letting them test 10x more products and identify bestsellers faster. Built an AI-powered cold email system for a job board that scrapes prospect data and generates uniquely personalized messages for each recipient, achieving reply rates that crushed industry averages. Let's talk about what I can automate for you. Send me a message and let's turn your biggest time-sink into your competitive advantage.

Hi, I'm Aram 👋 I've worked with multibillion-dollar companies like Microsoft, Google, Apple, and Boeing, where I did: 🟢 $300K revenue / 80% market share — Built a Professional Engineering exam platform. 🟢 $100M VC outcome — Built operations systems enabling 10× growth (50 → 500 employees). 🟢 $120M Smart Grid program — Architected automated contract administration systems. The longer version (if you have a minute): Pleasure to meet you, I’m Aram 👋. My background is in engineering, large infrastructure programs, and building technical systems that allow organizations to scale. Over my career I have worked on infrastructure and technology initiatives totaling over $10B in funding with organizations including Oracle, Autodesk, Microsoft, Google, Apple, Boeing, PwC, UCLA, USC, CalTrans, the City of Los Angeles, and multiple major public sector agencies. One of the largest programs I worked on was a $1B+ Smart Grid modernization initiative involving LADWP, Oracle, and the U.S. Department of Energy. As a technical engineering project manager I was responsible for managing approximately $120M of the program and designing automated systems for complex contract administration and program operations. The automation framework reduced administrative overhead and saved approximately $1.5M in contract administration costs while supporting systems serving over 4 million utility customers. Throughout my career I have designed and implemented operational systems that support large engineering programs, infrastructure deployments, and complex technology implementations. This includes systems for project delivery, contract administration, reporting, and program operations used across large teams and multi-year infrastructure initiatives. In addition to enterprise infrastructure work, I have also built and launched my own products. I created a Professional Engineering exam platform that captured approximately 80 percent of its niche market and generated over $300K in revenue. I have also designed internal operational systems that supported companies scaling from 50 to 500 employees, contributing to the operational infrastructure behind a $100M late-stage venture capital funding round. Today I focus on building AI-powered automation systems and operational infrastructure for engineering firms, technical consulting organizations, and B2B technology companies. Typical systems I build include business development automation pipelines, project management systems for engineering teams, proposal and contract workflow automation, and AI knowledge systems that allow organizations to query internal technical documentation. I commonly implement these using platforms such as n8n, Make, AI APIs, automation frameworks, databases, and custom integration architectures depending on the client environment. Most organizations I work with are highly capable technically but struggle with operational complexity. Critical processes are often run through spreadsheets, email chains, and disconnected tools. My role is to design and implement the automation and operational systems that replace those manual processes with structured infrastructure that scales with the organization.
