Is your platform slowing down as you grow? I cut one client's API response times by 72% and their server costs by 38%. I'm a Senior Full Stack Engineer and Software Architect specializing in scaling SaaS and Fintech platforms. Most software problems don't show up on launch day—they appear at 1,000 users, then 10,000, when slow responses, rising cloud bills, and risky releases start costing you customers. I help founders and product teams fix that before it gets expensive, or after it already has. A Recent Rescue A client came to me after investing over $30,000 in a SaaS platform that couldn't support growth. API responses took over 3 seconds, infrastructure costs kept climbing, and every release risked breaking something due to a tightly coupled architecture. I redesigned the architecture, optimized the database, added asynchronous job processing and caching, and modularized the backend. The Result: API response times down 72% Infrastructure costs down 38% Deployment times cut by more than half Platform ready for 10x more concurrent users without a rebuild How I Work Every good software product starts with understanding the business, not writing code. Before development begins, I learn your goals, users, and technical challenges to recommend solutions that solve today's problems without creating tomorrow's technical debt. Clean, scalable architecture built for growth Security and performance from day one Modular, documented code your team can build on Regular progress updates, so you're never guessing Practical advice that balances speed, quality, and cost My Process Discovery: We define your goals, users, and constraints. Architecture Review/Design: I map the system and flag risks early. Build in Milestones: You see working progress, not promises. Test and Harden: Performance, security, and edge cases. Launch and Support: Smooth deployment, then ongoing improvement. What I Build New products and MVPs, from idea to production SaaS platforms and multi-tenant systems Fintech apps: lending, wallets, payments, and dashboards Platform modernization and performance tuning API design and third-party integrations Tech Stack React, React Native, Node.js, Python, PostgreSQL, REST APIs, Docker, and AWS. Who I Work Best With Founders launching a first product, startups whose codebase is slowing them down, and teams that need a senior engineer to lead architecture or fix what's already built. I'm happy to work alongside your in-house developers. Let's Discuss Your Project Available for fixed-price projects, hourly engagements, or architecture audits with a written report and prioritized fix list. Not sure your current architecture can support where your product is going? Send an invite to discuss. Walk me through your product, challenges, or vision, and I'll point out risks and recommend the best technical approach.
