Software Development Engineer II
I build and own production-grade SaaS — backend systems, CI/CD pipelines, self-designed staging & live deployment architectures, billing engines, and AI-powered platforms.
I'm a Software Development Engineer with 3+ years building and owning production-grade SaaS products. I specialize in backend engineering and CI/CD pipelines — with hands-on frontend ownership when needed. I've delivered complete SaaS billing systems (Stripe, SSLCommerz), self-designed staging & production deployment architectures with zero-downtime, tag-based auto-releases, and AI-powered content platforms. I actively use Claude Code & GitHub Copilot to amplify output and code quality.
Leading all backend & frontend engineering for the GetGenie AI platform. Architecting and building the YoSuite ecosystem (YoHRM · YoPM · YoCRM) and the YoCore infrastructure layer — handling auth, token management, and multi-gateway billing across all products. Integrating LangChain, Google Search Console & Analytics; leveraging Copilot & Claude Code.
Built and owned the YoSuite SaaS product end-to-end (Node.js, TypeScript, React, Docker). Single-handedly designed the full zero-downtime staging & live deployment architecture — Caddy auto-HTTPS reverse proxy, Dozzle container-log monitoring over SSH, SSH-based environment management, Docker, and GitHub Actions with tag-based auto-release. Delivered a complete Stripe billing system with plan tiers, prorated subscriptions, add-ons, and webhook lifecycle management.
Built Solidity smart contracts (ERC20, ERC721) on BSC and Polygon. Developed Node.js + PostgreSQL backends with Stripe & PayPal webhook integrations.
Delivered Blockchain / Solidity / Ethereum training and hands-on lab sessions.
A multi-product B2B SaaS ecosystem — the parent brand for YoHRM (HR management · staging · prod), YoPM (project management · staging), and YoCRM (coming soon). Each workspace gets isolated subdomain routing (workspace_slug.yosuite.net/hrm) with full custom domain support (custom_domain.com/hrm). Self-designed zero-downtime deployment pipeline — Caddy auto-HTTPS, Dozzle log monitoring over SSH, Docker, GitHub Actions tag-based auto-release.
The centralized infrastructure layer that powers the entire YoSuite ecosystem. Products connect via a product-agnostic SDK and immediately inherit cross-product authentication, session & token lifecycle management, and multi-gateway billing — Stripe and SSLCommerz — with no redundant integration work per product. Architecture, billing adapter pattern, SDK, and full implementation built from scratch.
Sole engineer with full ownership of backend, frontend, and deployment for an AI content writing and SEO research platform. Integrated OpenAI & Hugging Face via LangChain pipelines, Google Search Console & GA4 for SEO insights and analytics, Google Ads, Apify for web scraping, Copyscape for plagiarism detection, and Keywords Everywhere. Designed and owned the complete production deployment infrastructure.
Cross-border payment platform engineered for freelancers and independent professionals. Integrated Google Pay & Apple Pay via Revolut + Stripe, Stripe Payment Links, and PayPal — unified under a single webhook event pipeline handling multi-currency transactions, real-time payment confirmation, and automated payout flows.
Social media platform with an integrated NFT marketplace. ERC20 token reward mechanics and ERC721 NFT minting deployed on BSC and Polygon, backed by a Node.js + PostgreSQL service layer.
Published production-grade utility libraries: pub/sub abstractions for Kafka and RabbitMQ, a libsodium-backed symmetric encrypter, and more — collectively downloaded thousands of times.
