A startup founder came to me with a four-week investor deadline, a constrained enclosure, and no schematics. We engineered a dense 6-layer IoT PCB layout with full signal integrity simulation it powered up perfectly on the first pass, secured their seed round, and earned this review: “He didn’t just design a circuit board, he literally saved our investor launch.” That outcome isn't luck. It's the result of treating every hardware engagement as a production problem from day one, not a prototype exercise. I'm a Top Rated Plus PCB design engineer and electrical engineering specialist with 10+ years of experience and 85+ completed hardware deployments across IoT devices, industrial automation, robotics platforms, and medical device electronics. My work covers the full hardware development cycle, schematic design, multilayer PCB layout, embedded systems integration, signal integrity optimization, and manufacturing-ready deliverables that hold up through fabrication and real-world operation. Recent projects include a flexible PCB design for NIR (near-infrared) sensing and a Bluetooth lapel microphone board built on the Nordic NRF52840 compact, signal-sensitive hardware where PCB layout discipline, impedance control, and RF interference management directly determine whether the product works. ESP32 and STM32 embedded systems, BLE and WiFi communication hardware, motor controllers, and power electronics for EV and industrial automation applications make up the rest of my active project history. ● How I Work: I design primarily in Altium Designer and KiCad, with schematic design and IPC-compliant component sourcing completed before layout begins. Every PCB layout is built around DFM and DFA principles, high-speed routing, impedance control, EMI/EMC mitigation, differential pair routing, and thermal management so respins stay rare and first-pass success rates stay high. Deliverables include fabrication-ready Gerber files (RS-274X/ODB++), CPL/pick-and-place files, and production-ready Bills of Materials. No loose ends at handoff. ● Core Expertise: ⁃ PCB Design & Layout: Multilayer PCB layout (2-layer to 12+ layer), high-speed routing, signal integrity analysis, impedance matching, EMI/EMC mitigation, rigid-flex PCB design, thermal management, DFM/DFA optimization ⁃ Schematic Design & Circuit Engineering: Schematic capture, analog and digital circuit design, mixed-signal circuit development, power electronics design, BOM optimization, component lifecycle analysis ⁃ Embedded Systems & IoT Hardware: ESP32, STM32, ARM Cortex embedded hardware development, BLE and WiFi system integration, low-power IoT hardware design, embedded firmware-ready platform development, wireless sensor node design ⁃ ECAD Tools: Altium Designer, KiCad, Autodesk Eagle footprint and library generation to IPC standards ⁃ Manufacturing Deliverables: Gerber files (RS-274X / ODB++), pick-and-place/CPL files, production BOM, fabrication, and assembly documentation. ● Who I Work With: My strongest engagements are with founders and engineering teams who treat hardware development as a serious investment not a race to the cheapest PCB layout quote. ● Who are strong fit: ⁃ You are building a market-bound product and understand the real costs of component sourcing and PCB prototyping cycles ⁃ You are ready to invest the time and budget that production-quality electrical engineering actually requires ⁃ You come with defined requirements a clear concept, target specs, or reference schematic design ⁃ You are available for brief milestone reviews to keep the PCB design aligned throughout development ● We are not a fit if: ⁃ You need a homework assignment or university thesis completed. I work exclusively on commercial hardware ⁃ You want to skip signal integrity checks or DFM rules to reduce cost, but still expect a reliable, production-ready board ⁃ You need a complex multilayer PCB design completed in two to three days responsible embedded systems engineering requires a realistic timeline ● Track Record: 100% Job Success · Top Rated Plus · $200K+ earned · 5,700+ hours delivered Upwork hourly and fixed-price engagements, from initial schematic design through manufacturing handoff. If your project is production-bound and you need a PCB design and embedded systems engineer who takes full ownership from schematic design through fabrication-ready deliverables invite me to your job or book a direct consultation to review PCB stack-up strategy, circuit architecture, and component selection before we begin.

If you're getting clicks but not enough leads, or your cost per lead keeps climbing, the first thing I do is figure out why before touching your budget. I run Google Ads and Meta Ads for ecommerce brands and service businesses, and most clients come to me after someone set things up but didn't stick around to make it pay. I currently manage over $900k per quarter across Google and Meta, ecommerce and DTC brands at $5K to $50K+/month, and service businesses too. I work with accounts at $3K/month in spend and up, where there's enough budget and data to move the numbers. I treat every dollar like it's mine and optimize for leads and revenue you can bank. Junk leads trace back to lead quality. I fix that with search-term cleanup, negatives, and tighter targeting to bring your cost per lead down. Most accounts treat Google and Meta as two separate channels. One strategy, one report, and attribution that ties spend back to real CAC pulls them into a single system. Conversion tracking comes first. GTM, GA4, and server-side get fixed before anything else, because when GA4 and the ad platforms disagree you stop trusting your own numbers. Creative is where most ad spend leaks. The direct-response variations I build get tested against what actually converts. Scaling without CAC blowing up means fast single-variable tests: kill the losers, push the winners, and judge everything on real CAC and ROAS. Clicks are wasted if the backend leaks. Landing pages, retargeting, and CRM automation in GoHighLevel keep your leads warm and followed up. Inherited a messy account? You get an audit and prioritized findings first, then a restructure, with the plan on the table before I touch the build. For ecommerce and DTC brands I also run CRO on the 80/20, checkout and AOV. For local service businesses, call tracking and geo-targeting measured on booked jobs. Results - 97% reduction in cost per lead for a home improvement contractor - 13.24x ROAS and $619k in sales for a furniture DTC brand (Meta Ads) - 7.66x ROAS and €268k in sales from zero in 90 days (gym equipment, Google Ads) - ROAS from 249% to 466% in 3 months for a global beauty brand - 77% more qualified leads and 32% lower CPA for a B2B SaaS company What I Work With Google Ads (Search, Shopping, PMAX, Display, YouTube), Meta/Facebook Ads, Bing Ads. GA4, Google Tag Manager, Meta Pixel, server-side tracking (Stape). Google Merchant Center, Shopify. GoHighLevel, Zapier, Make, n8n. Day to day: keyword research, negative keywords, bid strategy, ad copy testing, A/B testing, retargeting, landing page optimization, and reporting. "Since working with Kamil, average monthly sales increased from $4,000 to $25,600" - Peter S, Loft Design Not a fit if you want someone who reports clicks and impressions, needs weeks before acting, or can't define a numeric kill rule. I'm measured on output. If your ads aren't performing, or you can't tell because you don't trust the numbers, message me and I'll tell you the first thing I check. Kamil

He was knowledgable, quick to implement, and made reasonable dev decisions! As a dev, it's always nice to work with someone who knows their stuff!" - Lighting Design Wishlist, Shopify engagement, 5-star Upwork feedback What separates a Shopify developer who ships from one who blocks projects: subsystem understanding. After 10 years and 100+ Shopify builds, I know which problems become migration blockers (Recharge subscription portability, 301 redirect mapping, variant matrix integrity) and which are theme-rebuild surface work. A Shopify developer who has not shipped Shopify Plus checkout extensions or Hydrogen storefronts will treat both as the same risk profile. They are not. 🏆 Flagship Shopify projects: ▪️ 𝟭𝟬𝟬% 𝗣𝘂𝗿𝗲 - leading natural beauty brand on Shopify Plus. Custom Liquid theme, checkout extensions, subscription flow.

𝗪𝗛𝗢 𝗜 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 Established beauty, wellness, home goods, supplement, and retail brands building or rebuilding on Shopify or Shopify Plus. Founders and operators who need clean Liquid code, documented theme architecture, and a Shopify store their team can maintain after handoff. Brands migrating from Magento, WooCommerce, BigCommerce, or WordPress to Shopify. Brands ready for Headless commerce with Hydrogen and Oxygen. Brands fighting Core Web Vitals scores that hurt conversion and SEO. 𝗠𝗬 𝗣𝗥𝗢𝗖𝗘𝗦𝗦 Every Shopify developer engagement starts with a review of your current store or requirements before any code is written. I send a scoping breakdown with subsystem-level risk map (especially on migrations: SEO via redirects, customer data integrity, subscription continuity, variant matrix integrity, theme rebuild parity). Clean Liquid, documented theme architecture, and a Shopify store your team can manage after handoff without a developer on every update. 𝗦𝗨𝗕𝗦𝗬𝗦𝗧𝗘𝗠𝗦 𝗜 𝗦𝗛𝗜𝗣 🔧 Shopify Storefront API integration on Headless builds: product, collection, cart, and customer data flowing into a Hydrogen frontend on Oxygen. Webhook-driven sync where state matters. ⚙️ Shopify Plus checkout extensions for custom validation, address autofill, post-purchase upsells, and shipping logic via Shopify Functions. Native Plus features without legacy checkout.liquid limitations. 🧩 Liquid theme architecture on Shopify 2.0: sections, JSON templates, metafields, metaobjects, theme app blocks. Merchant teams edit content without touching code or calling a developer. 🌐 Shopify Markets for multi-region pricing and currency, native B2B for wholesale catalogs and company accounts, Recharge for subscription continuity across migrations. Subsystems most agencies underestimate. 🔌 App integrations every engagement: Klaviyo email, Yotpo reviews, Judge.me UGC, Recharge subscriptions, ERP sync via Admin API. Custom Shopify apps when off-the-shelf falls short. Share your Shopify store or requirements. Within 24 hours I will send a scoping doc with what needs to be built, what it will cost, and approach.
