I build backend systems for fintech, healthcare, and SaaS products where reliability is non-negotiable.
My most recent engagement was a US broker-dealer fundraising platform serving 10+ institutional clients โ where I owned 5+ backend subsystems end-to-end for over a year, from schema design through Azure deployment.
Real financial transactions. Real investor data. Real consequences if something breaks.
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
WHAT I HAVE ACTUALLY BUILT IN PRODUCTION
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
โ Bulk export pipeline โ processed 100,000+ investor records via chunked BullMQ jobs with streamed output to Azure Blob. Fully non-blocking API under heavy load.
โ White-label theming engine โ issuer customizations trigger background jobs that compile CSS bundles, save to Azure Blob, and inject via CDN into the frontend, eliminating per-request rendering overhead.
โ Offering versioning system โ complex state transitions, investor eligibility rules, and audit-safe data mutations for broker-dealer flows.
โ Event-driven notification pipeline โ BoldSign digital signing + SendGrid email, unified and fully traceable.
โ Zero-downtime .NET 7 migration of a live hospital management system โ modernized stack, resolved performance bottlenecks, no disruption to healthcare operations.
โ Ethiopian calendar engine built from scratch โ replaced all Gregorian logic across payroll, scheduling, leave, and reporting for a multi-country workforce platform.
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
WHERE I ADD THE MOST VALUE
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
โ You have a backend that works but feels fragile โ I find what breaks it and fix it properly.
โ You need a complex domain built right the first time โ payments, workflows, eligibility rules, audit trails.
โ You need async/background job systems that don't block, fail silently, or fall apart under load.
โ You need someone who takes full ownership of a subsystem โ not someone who needs hand-holding on every task.

Give me an AI document system or automation to build โ Iโll ship it so it runs for you 24/7. Thatโs my promise.
If you invite or message me, Iโll send a short personalized Loom on how Iโd approach your exact workflow.
I help businesses stop manual document work and ship production AI systems: multi-tenant knowledge apps, invoice/document agents with audit trails, and n8n workflows that write to Sheets, Slack, or your tools.
โข Multi-tenant RAG SaaS โ org isolation, RBAC, chat with sources
โข AI Workflow Agent API โ extraction, tool calling, full step logs + cost
โข n8n intake โ document in โ Agent API โ Sheets + Slack
โข Top Rated, 100% Job Success and reply within 0โ4 hours
โข Strong overlap with EU mornings and US afternoons (UTC+3)
I build custom FastAPI + Next.js systems and glue them with n8n โ not fragile no-code-only demos.
Also strong with Flutter when you need a mobile client on top of the API โ secondary to AI/backend work.
Not a fit if you need ML research, model training, or a cheap chatbot with no deploy plan.
