Senior Full-Stack Engineer and Founder of Harvest Mate. Five years shipping production-grade systems across Fintech and Agritech.
Built to scale, engineered to last.
From founding a SaaS startup to scaling systems — always as the engineer who owns the full picture.
Tools I've used in anger — across production systems, a funded startup, and fintech infrastructure serving thousands of users daily.
The real story behind the work — the architectural decisions, the tradeoffs, and the tech that doesn't fit on a résumé.
Farmers managing large-scale operations had no affordable, integrated digital platform. Pen-and-paper job scheduling, WhatsApp for maintenance alerts, and zero data-driven crop health visibility. Off-the-shelf tools were either too expensive, too generic, or required 3rd-party consultants to deploy.
Design, build, and ship a full B2B SaaS platform — solo — covering job scheduling, inventory, equipment maintenance, and satellite-powered crop health analysis. Constraint: no external dev budget, had to be production-grade on day one.
Chose a Node.js/GraphQL (Apollo) backend for its flexibility in federating complex agronomic data models. Python microservice for satellite pipeline work — Sentinel Hub's API returns multispectral GeoTIFF data requiring NumPy/Rasterio processing before it's usable. Kubernetes on GKE for predictable autoscaling during harvest season spikes. Next.js frontend for SSR SEO. Zod for schema validation across API boundaries. Husky + lint-staged for zero-tolerance code quality.
Active crop health monitoring across 1,000+ hectares of farmland. Job scheduling and equipment maintenance workflows live in production with real customers. Platform designed to scale from individual farms to cooperative networks — multi-tenant architecture ready from day one.
Traditional student identification systems rely on centralized databases, making them vulnerable to data breaches, duplication, and lack of cross-institution verification. Verifying student credentials across institutions is slow, manual, and prone to inconsistency.
Design and implement a decentralized identity system that allows secure, verifiable, and tamper-resistant student credentials using blockchain technology, while maintaining a simple and usable interface for real-world adoption.
Built a decentralized application (dApp) on Ethereum using Solidity smart contracts to manage student identities and credential verification. Developed a Next.js frontend integrated with Web3.js for wallet interaction and contract communication. Used Truffle for smart contract development, testing, and deployment, with Mocha for automated test coverage. Deployed contracts on an Ethereum test network to simulate real-world usage and ensure reliability.
Delivered a functional proof-of-concept demonstrating secure, decentralized student identity management. Enabled instant and trustless verification of credentials, eliminating the need for intermediaries and showcasing the potential of blockchain in academic systems.
I founded Prime Scale Solutions to take full responsibility for the products I build — not just writing code, but shaping direction, making trade-offs, and delivering outcomes. It reflects how I work: ownership-driven, product-minded, and focused on building systems that scale.
Design and development of web applications, backends, mobile apps, and high-converting landing pages. Built end-to-end with a focus on performance, clarity, and real-world usability.
Strong experience building SaaS products from the ground up — designing scalable architectures, multi-tenant systems, and clean APIs, with a focus on long-term maintainability and smart technical decisions.
Every part of the system is built with production experience in mind, shaped by years of delivering real-world software across fintech and SaaS.
Backend, frontend, infrastructure, deployment. One point of contact who understands the entire system, because they built it.
Built and operated a live SaaS solo. Architectural decisions are made with cost, scale, and business outcomes in mind, not just clean code.
CI/CD pipelines, automated testing, container orchestration, and monitoring are not upsells. They're how every project ships.
The clearest proof of what Prime Scale Solutions delivers: a full B2B SaaS platform for agricultural operations: job scheduling, inventory, equipment maintenance, and satellite-powered crop health analysis across 1,000+ hectares. Designed, built, and shipped solo from concept to live customers.
Open to Senior / Staff Engineer. Remote or Europe-based. If you're building something that matters — let's talk.
