I build production AI systems that hold up under real usage — not demos, not prototypes. Systems that ship, scale, and stay reliable when real users start hitting the edge cases.
What I do:
- Production LLM systems — RAG pipelines, multi-agent orchestration, and the eval frameworks that actually measure whether a change improved anything.
- AI architecture & builds — designing and shipping the system properly the first time, then handing it off clean to your team.
- Cost & reliability engineering — controlling inference spend, hardening prompts, and adding the observability production AI actually needs.
- Team enablement — installing the Claude Code and agentic-development workflows that make your engineers dramatically faster.
Recent work:
- TraceLayer — compliance-automation SaaS (11 frameworks, 120+ integrations) built solo to paying customers in 21 days using multi-agent LLM orchestration.
- Kandji — enterprise-scale RAG and LLM automation with MLOps for a leading device-management platform.
- Acumatica — multi-agent LLM pipeline with stateful context memory, running in production.
- Fresh Earth — real-time carbon-tracking and ESG compliance platform (Chief of AI).
- Volvo Group — predictive-maintenance ML and IoT pipelines (15% less fleet downtime).
Stack: Python, FastAPI, Next.js, React, TypeScript, LangChain, OpenAI and Claude, RAG, vector databases, AWS, Docker, PostgreSQL.
How I work: embedded with your team, not an external vendor delivering tickets. Weekly demos, async by default, full context on what you are building and why.
If you have a real AI engineering problem — an LLM feature that has to work in production, a system that needs to be built right the first time, or a team that needs to move faster — let's talk.

Hey there, thanks for stopping by! I’m Boris, a digital marketer with 7+ years of experience helping brands grow through both paid and organic strategies.
Paid Social (Creative Strategy)
I own paid creative end to end. Research the offer and the buyer, build the angle, write it, storyboard it, then direct UGC creators and editors until it's a finished ad that stays on brand and is ready to test.
- Track record:
Creative for more than 70 products across multiple brands, running multiple new product launches a week, while iterating on existing ones.
They stayed profitable while brands scaled past $10k - 50k/day in ad spend.
Worked across D2C, e-commerce, and affiliate marketing, so I know the difference between selling a brand, moving product at volume, and driving a click that has to convert on someone else's page.
- What's included:
My Strategy:
Offer, market, and competitor research
Positioning and messaging map
Creative angles built in batches, not one-offs
Weekly testing and iterations
- Writing
Short-form ad scripts (UGC, testimonial, founder, problem/solution)
VSL scripts and structure
Hook variations for testing, multiple per concept
Primary text, headlines, and supporting ad copy
- Visualization
Shot-by-shot storyboards
Shot lists and creator filming briefs
Edit direction and notes for the video team
- Execution and process:
Writing clear briefs and directing UGC creators to shoot exactly what the concept needs
Working closely with editors through revisions to a finished cut
Keeping every asset aligned to brand guidelines and voice
QA on rough cuts before delivery
Hook and angle banks the team pulls from every week
Repeatable briefing and production workflow so output stays consistent at volume
Tools I work with:
I use AI and modern production tooling daily to move faster without dropping quality:
- AI video and image: Sora, the Wan stack, Seedream/Seedance, Veo, Kling, Midjourney, Nano Banana, Infinitalk
- LLMs: ChatGPT, Claude, Gemini, Grok, for research, scripting support, and angle generation
- Collaboration and workflow: ClickUp, Asana, Frameio, Notion, Google Docs, Slack, Miro
Frameio for review rounds and ClickUp/Asana for keeping the production pipeline on schedule mean feedback and delivery stay clean even at high volume.
- How I start a collaboration:
I don't jump straight to writing. First I audit what you already have running: what's been tested, what won, what flopped, and why. That tells me where the money is before I spend yours. From there I bring you a small batch of fresh angles with scripts and boards, we test, and we scale what works. Low risk for you to start, and you see how I think before committing to a retainer.
- What I need from you to onboard:
The quality of the work depends on this, so I ask for it up front, not halfway through:
All past performance reports and ad account data. Everything you've tested, spend, ROAS, CPA, what won and what died. This is what stops me from repeating tests you've already paid for.
All existing video material and raw footage. Past ads, creator content, unused clips. Winning angles are often already sitting in your drive.
Clear brand direction. Where you want the brand to go, positioning, voice, guidelines, and who the customer actually is. I build creative toward that direction, not just this week's ad.
Offer details, margins, and the funnel the ad points to.
The more of this I get on day one, the faster the first winning batch comes. Clients who hold this back get slower, more generic work, and it's usually their own results that suffer.
- Standalone entry point: Ad and VSL audit. Teardown of what's running now, why it isn't converting, prioritized fixes, and new angles to test. Sold on its own or as the first step into a retainer.
- Engagements: one-off scripts or storyboards, a creative sprint (concepts plus scripts plus boards for a batch of ads), audit, or a monthly retainer where I run the whole creative pipeline.
Social Media Marketing (Organic)
- Positioning: Organic isn't just posting on a schedule. It's building an audience that actually cares, and it's where I prove angles cheaply before anything goes into paid.
- What's included:
Content strategy and pillars tied to a real business goal, not vanity metrics
Content calendar and planning
Short-form content direction (concepts, hooks, formats per platform)
Scripting for organic short-form
Influencer marketing: finding the right creators, outreach, and running the collaborations
Meaningful community management: real conversations, not copy-paste replies, so the audience sticks
Organic growth through relationship building, with other accounts, creators, and the community itself
Reporting on what's working, and feeding the winners into paid
- Engagements: strategy and calendar build as a one-off, or ongoing monthly management, community, and content direction.

Ecommerce · Performance Marketing · Brand Building
🖥️ I'm an ecommerce operator and performance marketer with over 3 years of hands-on experience across the entire commercial stack, from paid media and creative production to funnel optimization, brand building, and product development.
🛒 I've worked every side of an ecommerce business: as a freelancer doing different types of jobs, as the manager holding cross-functional teams together, and as a founder who has built brands and products from a blank page all the way to sold-out launches.
👤 My strength is that I understand how the pieces connect. I can research a customer, shape the angle, write the script, produce the creative, run the ads, fix the funnel, and read the analytics, without needing a separate specialist at every step. I'm equally comfortable working inside established SOPs or building the process myself where none exists.
Above all, I genuinely enjoy and love ecommerce and digital marketing, and I'm always looking to learn more and grow, staying open to new tools, methods, and practices as the field keeps evolving.
I'm kind and easy to work with, communicative and open, proactive and self-motivated, and I stay positive and level-headed under pressure. I enjoy working as part of a team, but I'm equally effective on my own.
Outside of work, I keep a healthy and active lifestyle. The gym, boxing, and physical activity are my main hobbies, and I don't smoke or have any problems with alcohol.
Core skills:
- Advanced Meta Ads - full campaign structure, creative testing, scaling and troubleshooting, with hands-on experience managing budgets of up to $10,000 per day
- Basic Google Ads - search campaign setup and management
- Static and video ads from scratch - built end to end, from concept and script through to the final edit
- AI image and video generation - producing ad creative and content using modern AI tools.
- Copywriting and scripting - for ads, landing pages, and video, written to match the customer and the angle
- Creative strategy and direction - ad creative, UGC, content, and video ad strategy, plus creative direction and product photography direction, including briefing creators and agencies for video shoots
- CRO and landing page building - improving conversion rates and tightening funnels across the customer journey
- Full Shopify knowledge - deep working command of the platform and its app ecosystem
Page builders - GemPages and PageFly
- Customer research - building avatars, angles, and concepts that drive creative and messaging
- Market research and product-market fit - finding product-market fit through market research and competitor analysis
- Product sourcing and development - from finding suppliers to shaping the product itself
- Analytics and performance analysis - reading the data to guide scaling and optimization decisions
- Claude for marketing - Cowork, Skills, and Automations to speed up research, creative, and operations
- Up to date with AI - actively following and learning new AI tools, and keeping current with developments across the AI world
- Basic email marketing
- Design and editing tools - Canva, Figma, and CapCut
- Tooling - comfortable with most task management and team communication apps
Ways of working
- Team management and cross-team communication
- Reliable, responsible, and always on time
- Quick learner who's highly adaptive
- Able to work with or without SOPs
- Strong communicator who's always ready to learn more
