WHAT I DO
I build systems that move data reliably between platforms, automate operational work, process financial files, expose failures and reduce manual intervention: REST APIs, multi-database aggregation, scheduled file processing, CRM integration, devops, and observability.
REST design, microservice boundaries, CRM and portal connectivity
Multi-database aggregation, schema design, performance tuning
File ingestion, validation, splitting, masking, scheduled delivery
AWS deployment, containers, CI/CD, environment consistency
Logging, dashboards, faster incident diagnosis
Compliance-aware design, sensitive data handling in transit
Projects
Fintech · ASP.NET Core, MySQL, SQL Server, CRM
A REST API on ASP.NET Core that aggregates telemetry from MySQL and SQL Server, exposes analytics to a merchant portal and mobile app, and routes in-app questions into CRM via automated case creation.
Fintech · ASP.NET Core, Hangfire, file integration
A listener-based ingestion pipeline that picks up files, runs validation and splitting through Hangfire background jobs, masks card and account-style data, and delivers transformed output to the accounting server on schedule.
Personal project · SME financial operations · Claude API, Supabase, Express 5
A chat-first financial operations assistant where Claude plans the operation, typed handlers execute it, and all maths (totals, VAT) stays deterministic on the backend.
Personal project · Job application intelligence · React 19, Claude API, Supabase, Cheerio
A pipeline that scrapes, normalises, and deduplicates roles, then uses LLM evaluation with qualification gating so a CV is only generated when a role clears a fit threshold.
