Senior backend engineer with 12+ years across various domains.

Before recent experience at an F500 corporation, I built and owned key backend components at a couple of early-stage startups, one of which grew to hundreds of thousands of users.

Looking primarily for backend roles, also interested in performance-oriented systems-level opportunities (C++, OS, CUDA kernels, etc.), only project experience so far.

Remote: Yes

Résumé/CV: https://sanket-portfolio-gold.vercel.app/

I'm a full-stack developer with 2.5+ years of experience building production web and mobile applications for startups, agencies, and small businesses.

Following are the projects I've worked on:

https://www.valoravalet.com/ :- A valet parking app with admin dashboard, multiple locations, and payment integration of stripe, square etc.

https://www.saleor.city :- AI-powered SaaS to create customer store-front and manage voice enabled store.

https://www.analytics.oceanwaveweb.com :- A tool to track the visitors visiting your site.

https://www.among.health :- A clinician-reviewed AI platform with real-time transcription, structured AI outputs, role-based access, and doctor approval before patient visibility

https://www.stash.market :- a multi-tenant commerce product with inventory, storefronts, and database-level tenant isolation

And almost 11+ more. I enjoy shipping products quickly, working directly with founders, and owning features from idea to deployment. I'm comfortable working independently and across the full stack.

I'm looking for full-time, contract, or freelance opportunities with startups or product companies where I can build impactful products and continue growing as an engineer.

For one year I reverse-engineered the major education platforms — Google Docs, Microsoft Office, Nearpod, Kahoot, ect. — so that AI agents can drive them on a teacher's behalf and automate classroom workflows. The work runs in over 10,000 classrooms today.

Building agents against production code you don't control is harder than it sounds. The code is mangled, so first you have to understand how the app was built and then take it apart from the outside. It's reverse engineering, but it depends on knowing how to build the thing in the first place.

The role came with monthly compliance and security training centered on FERPA, so I'm fluent in handling student data responsibly. That's not new ground for me. I spent five years building on Drupal, which the most prestigious learning institutions still run today, and version control and access control were the hard part of every project. Student data is the same problem.

I've been building browser agents and browser automation since 2018, well before it was a category. That's paired with 13 years of building dynamic, data-heavy UIs for web and mobile.

I've also built admin dashboards for a custom legal document management system. And a CRM for email marketing, with a drag-and-drop interface for designing and branding email templates for social campaigns. I've taken several companies from 0 to 1, as a consultant and as a full-time employee, across fintech, streaming, real estate, education, marketing, and media. I've worked at a 130-person AI company and on a 7-person team where I wore every hat. I do my best work on small, fast-moving teams.

Senior Product Designer | Design Engineer, 15+ years. I cover the whole design process and ship the front-end myself.

I've worked solo and in teams, at early startups and mature products, across EdTech, enterprise SaaS, fintech, healthcare, and dev tools. The work spans user research, UX and interaction, visual and brand craft, and design systems. I also write production HTML, CSS, JS, and React, so the design holds up in real code.

I can own a product end to end on my own, or slot into a team and move with it. I like early, messy problems and working close to founders and engineers.

Senior Tech Lead & AI Engineer with 8+ years of experience. I operate effectively at two ends of the spectrum: architecting massive, highly regulated systems for Tier-1 banks (UBS, HSBC) and driving rapid, from-scratch execution for AI startups.

I don't just glue APIs together; I build robust architectures around them. I am looking for a challenging remote role (Tech Lead / Senior AI/Fullstack Engineer) where I can leverage both my deep frontend expertise and my hands-on AI engineering background.

Recent highlights: * *Enterprise:* Currently leading frontend architecture at UBS for a mission-critical post-trading platform, handling millions of daily transaction rows with sub-second WebSocket updates. * *AI/Startups:* Bootstrapped an AI-driven CBT platform (HeadSanctuary) featuring a custom RAG pipeline for unlimited memory context, complex form engines generated via JSON schemas, and uncensored LLM research for therapeutic contexts. * *Developer Experience:* Implemented AI-driven QA workflows using MCP/LLM agents to generate and maintain Playwright e2e tests, significantly reducing regression time.

PHP/JS/TS Development, Extremely competitive rates available.

I build new projects and revitalize legacy code. I work mostly with Laravel and React/Inertia or Livewire.

I integrate modern tools pragmatically, adding real-time features via Websockets (Laravel Reverb etc) and AI capabilities like RAG for context-aware search and content generation.

I develop methodically – implementing tests for new features and maintaining clear documentation while keeping sharp focus on shipping tangible results. Through proactive communication, we'll collaboratively define the sweet spot between code quality and delivery pace.
