Previously Senior Engineer at JustEat, Staples, and Finzly. 9+ years building production systems at scale, supporting 100k+ active users. I design systems that directly improve business margins through performance, reliability, and cost efficiency. Impact: -42% Cloud Spend | 94% Faster Data Pipelines | $2B+ processed on systems I helped design and operate. 𝐈𝐍-𝐇𝐎𝐔𝐒𝐄 𝐒𝐀𝐀𝐒 𝐌𝐈𝐍𝐃𝐒𝐄𝐓 & 𝐓𝐎𝐓𝐀𝐋 𝐎𝐖𝐍𝐄𝐑𝐒𝐇𝐈𝐏 I operate like a technical co-founder, not a ticket-based freelancer. I take end-to-end ownership of architecture, scalability, and delivery. You define the business goal, and I design and implement the backend system to achieve it with minimal operational overhead and long-term scalability. From MVP to millions of users, I make architecture decisions based on performance, cost efficiency, and maintainability. 𝐏𝐄𝐑𝐅𝐎𝐑𝐌𝐀𝐍𝐂𝐄 & 𝐃𝐀𝐓𝐀 𝐄𝐍𝐆𝐈𝐍𝐄𝐄𝐑𝐈𝐍𝐆 If your system is slow or your cloud bill is increasing, I refactor architecture for both performance and cost efficiency. ◆ At Staples, reduced a core data pipeline from 90 minutes to 5 minutes (94% improvement) ◆ Optimized backend systems using caching, indexing, Kafka, and Redis to achieve millisecond-level latency ◆ Refactored legacy systems into scalable event-driven architectures where needed 𝐑𝐀𝐏𝐈𝐃 𝐌𝐕𝐏 𝐃𝐄𝐕𝐄𝐋𝐎𝐏𝐌𝐄𝐍𝐓 (𝐀𝐈 𝐀𝐂𝐂𝐄𝐋𝐄𝐑𝐀𝐓𝐄𝐃) Need to launch fast? I combine AI-assisted frontend generation with production-grade backend architecture. Using tools like Lovable, Bolt.new, v0, Supabase, and Cursor to accelerate UI development, while I design and implement secure, scalable AWS backends underneath. 𝐈𝐍𝐕𝐄𝐒𝐓𝐎𝐑-𝐑𝐄𝐀𝐃𝐘 𝐀𝐑𝐂𝐇𝐈𝐓𝐄𝐂𝐓𝐔𝐑𝐄 & 𝐂𝐎𝐌𝐏𝐋𝐈𝐀𝐍𝐂𝐄 Preparing for funding rounds or enterprise clients: ◆ Architecture audits to identify risks, bottlenecks, and cost inefficiencies ◆ Compliance-ready systems aligned with HIPAA, GDPR, SOC2, and PCI-DSS ◆ Clear technical documentation for investor and enterprise due diligence 𝐖𝐇𝐀𝐓 𝐈 𝐃𝐄𝐋𝐈𝐕𝐄𝐑 ◆ Cost-efficient backend systems optimized for real production workloads ◆ Scalable architectures designed for long-term product growth ◆ High-availability systems built for peak load reliability ◆ AI-integrated backend systems using OpenAI and AWS Bedrock 𝐑𝐄𝐂𝐄𝐍𝐓 𝐂𝐀𝐒𝐄 𝐒𝐓𝐔𝐃𝐘 A fintech platform was failing during traffic spikes, causing failed transactions and rising infrastructure costs. I re-architected their backend into a scalable event-driven system, optimized APIs, and removed database bottlenecks. Result: handled a 300% traffic surge with zero downtime and reduced AWS costs by 42% within one month. 𝐓𝐄𝐂𝐇 𝐒𝐓𝐀𝐂𝐊 𝐀𝐓 𝐀 𝐆𝐋𝐀𝐍𝐂𝐄 Languages: Java (Spring Boot), Node.js (NestJS), Python Cloud/Infra: AWS (Lambda, ECS/Fargate, DynamoDB, RDS, EventBridge, S3), Terraform, CDK etc... AI: OpenAI, AWS Bedrock, LangChain etc... Data: Redis, Kafka, Supabase etc... Tools: Lovable, Bolt.new, v0, Cursor base44, claude etc.. 𝐂𝐋𝐎𝐔𝐃𝐅𝐋𝐀𝐑𝐄 𝐄𝐃𝐆𝐄 & 𝐒𝐄𝐑𝐕𝐄𝐑𝐋𝐄𝐒𝐒 Cloudflare Workers (APIs), R2 (storage), D1/KV (data), Queues/Durable Objects (async), CDN/WAF etc... 𝐈𝐍𝐃𝐔𝐒𝐓𝐑𝐈𝐄𝐒 Fintech (PCI/GDPR), Healthcare (HIPAA), E-commerce, Logistics, Marketplaces 𝐑𝐄𝐀𝐃𝐘 𝐓𝐎 𝐓𝐀𝐊𝐄 𝐘𝐎𝐔𝐑 𝐀𝐑𝐂𝐇𝐈𝐓𝐄𝐂𝐓𝐔𝐑𝐄 𝐒𝐄𝐑𝐈𝐎𝐔𝐒𝐋𝐘? If you're building a serious SaaS product, you don’t just need code, You need architecture that scales, performs, and stays cost-efficient under real production load. Send 2–3 time slots, and I’ll review your system and suggest an architecture approach.
