Hi, I'm Jesse Krim. I turn customer problems into shipped mobile, web, and AI systems. My edge is the mix: sales instincts, startup operating reps, React Native and Next.js engineering, FanDuel-scale production experience, and three current products built end-to-end.
Hi, I'm Jesse Krim. I turn customer problems into shipped mobile, web, and AI systems. My edge is the mix: sales instincts, startup operating reps, React Native and Next.js engineering, FanDuel-scale production experience, and three current products built end-to-end.
I am strongest where the product is ambiguous, the customer matters, and the system has to ship.
React Native, Next.js, TypeScript, Laravel, PostgreSQL, Supabase, Expo, app-store releases, analytics, monitoring, and production APIs.
Embeddings, pgvector, semantic retrieval, streaming chat, schema validation, quality checks, automations, and model fallback paths without losing product context.
Sales-trained judgment across discovery, positioning, onboarding, activation loops, pricing, launch strategy, and distribution.
The actual path
I spent years trying to get close to startups before I had the technical skill to build the company I wanted. Sales taught me customers. Operations taught me urgency. Engineering gave me leverage.
The founder chapter has been expensive in time and mistakes: wrong paths, wrong questions, too much time thinking about fundraising before the product was right. Those lessons are now built into how I work.
I am looking for a serious full-time role where this range is useful: product engineering, applied AI, forward deployed engineering, or an early startup team that needs someone who can think, sell, build, and ship.
Startup apprenticeship
I moved to San Francisco, shared a room with a founder, worked from cafes, helped with decks, QA, customer work, and investor-facing material, and learned what early startup life actually feels like up close.
Sales and operations
I followed Brad Lea and Lightspeed VT to Las Vegas, moved from customer success into sales and operations at 23, then worked with Dan Lear training sales teams at dealerships and solar companies while selling seminar tickets on the road.
Self-taught engineering
I came home, went through a coding boot camp, taught myself React Native on the couch, and turned a coworking-space relationship into the internship that became my first real engineering job.
Mobile ownership
At Crew Me Up, the development team quit and I had to build full-stack features, product flows, and the next version of the app. At Next Gen HQ, I built the React Native app from scratch with a lean product, design, web, and backend team.
Scaled production
After three years of bootstrapped engineering, I joined FanDuel and worked on production OTT and sportsbook surfaces inside the largest engineering organization I had been part of.
Founder chapter
Get Mentors took me through the hard questions: raise or bootstrap, B2B or B2C, who the customer is, what the product should be, and which rabbit holes were distractions. The last six months of AI tooling finally made the pace match the ambition.
Current ventures, production roles, and high-pressure builds across AI products, consumer mobile, streaming, archives, family software, and scaled engineering teams.
Founder / Senior Mobile Engineer
Left FanDuel to build the startup I had wanted since I was 21, then rebuilt it from the ground up after hard lessons around market, product shape, and GTM.
Now a live AI-guided mentorship product across mobile, web, backend, semantic retrieval, streaming chat, mentor boards, goal journeys, release pipelines, and marketing automation.
Founder / Product Engineer
Conceived and built an AI-forward listening product with a senior UI/UX designer for one of the deepest live music archives on the internet.
Proof that I can turn a messy archive and passionate community into a structured product system with search, source comparison, offline UX, and AI-guide direction.
Founder / Mobile Engineer
Built a private family memory product after seeing how bad the default camera-roll experience is for preserving a child's early life.
Proof that I can build emotionally sensitive consumer software with family auth, baby timelines, milestones, letters, invites, photo discovery, and native face matching.
Full-stack builder
Built and shipped a memorial website for my dad in roughly five days, including stories, gallery, admin CMS, comments, reactions, emails, and private family areas.
Proof of speed, care, taste, resilience, and full-stack execution under real emotional stakes.
Software Engineer
Moved from bootstrapped startup engineering into the largest engineering organization I had worked in, building production OTT and sportsbook surfaces.
Proof of production engineering inside a scaled consumer sports product organization.
Lead Software Developer
After the development team quit, I took on full-stack mobile ownership, built backend features, designed product flows, and helped lead the next version of the app.
Proof of mobile ownership, product judgment, team leadership, and execution in a messy production environment with 4k+ users.
