HERON (GEK TERNA Group)

Interbank Payment File Transfer

A production batch-transfer service moving settlement files from a national interbank clearing system into an enterprise ERP over SFTP, on a fixed daily schedule, replacing a manual operations task. Runs on Azure Functions with durable transfer state in blob storage.

Highlight

Safely re-runnable via organization-scoped idempotency keys: re-execution after partial failure never re-delivers a file.

Marketing Consent & Unsubscribe Platform

The public REST API, database schema, and ingestion pipeline behind a national energy retailer’s marketing preference pages. Recipients act on personalized campaign links; decisions sync to the corporate CRM in real time.

Highlight

Two-stage auth: caller credentials validated against Microsoft Entra ID, then a short-lived RS256 JWT bound to the link identifier, published via a self-hosted JWKS endpoint.

Enterprise KPI Analytics Platform

A full-stack internal portal for corporate KPI management: dashboards, quarterly goal/actual editing, field-level audit with revert, threaded comments, cross-year comparison, and server-side export to Excel, PDF, and PowerPoint. Access control runs on manual Microsoft Entra ID token verification with role-based access control, and the service is backed by 100% line coverage.

Highlight

Manual JWKS-based Microsoft Entra ID token verification, RBAC, HttpOnly cookie sessions with double-submit CSRF, correctly bypassed for bearer-token callers.

IT Portfolio & Roadmap Workspace

A portfolio-management workspace over live issue-tracker data: a Gantt timeline, a what-if scenario planner across six milestone dates per initiative, a top-priority board, and a portfolio analytics dashboard. The planning surface supports per-field undo and a dedicated scenario mode for testing uncommitted changes, and the analytics layer runs on roughly 27,000 lines of feature-first TypeScript.

Highlight

In-place planning surface with per-field undo, per-row sync status, session-persisted unsaved work, and a scenario mode isolating uncommitted changes.

Consumption File Splitter & Reconciliation

A queue-triggered Azure Function that splits very large consumption files from the national electricity distribution operator into ERP-ingestible segments, with a reconciliation report proving the split is lossless. Splitting is domain-aware (records are grouped by delivery point and calendar month so no logical unit is fragmented), and reconciliation uses exact-arithmetic, arbitrary-precision decimals so spreadsheet rounding cannot mask a discrepancy.

Highlight

Domain-aware splitting: records grouped by delivery point and calendar month, whole groups packed into bounded batches; a logical unit is never fragmented.

Multi-Source Document Assembly

An asynchronous service that collects every document related to a commercial record from three source systems (an AWS S3 archive, a customer portal on Azure Blob, and a third-party quoting platform’s API), merges them into one PDF, and files everything into SharePoint. Attachments are deduplicated by content hash before processing, and a page-by-page fallback salvages readable pages from partially corrupt PDFs so one bad attachment can never fail a request.

Highlight

Content-hash deduplication before processing, since the same attachment legitimately appears in multiple systems.

Cross-Cloud Document Delivery (Azure ↔ AWS)

An authenticated Azure Function letting Azure-hosted workflows deliver documents securely into a partner platform’s AWS S3 bucket, with AWS Signature Version 4 implemented from first principles. The SigV4 implementation covers canonical request construction, credential scoping, and chained HMAC-SHA256 key derivation, with an injectable clock that keeps signatures deterministic under test.

Highlight

Hand-built SigV4: canonical request construction, credential scoping, chained HMAC-SHA256 key derivation, with an injectable clock making signatures deterministic under test.

  • Azure Functions
  • AWS S3
  • HMAC/SigV4

Finance Data ETL to Benchmarking Platform

A scheduled ETL consolidating billing, credits, settlements, contracts, and aged balances from an Amazon Redshift warehouse and a SQL Server CRM, delivered to a third-party benchmarking platform’s API, fully in-memory on Azure Functions. Every extraction query runs behind parameterized builders with explicit column contracts, and per-source failure isolation means one unavailable store degrades the run rather than aborting it.

Highlight

Every extraction query behind parameterized builders with explicit column contracts: schemas asserted, not inferred.

  • Amazon Redshift
  • SQL Server
  • Azure Functions

Protera Technologies

CMDB and Cloud-Cost Analytics Platform

A production platform consolidating configuration and cost data from an ITSM system and two public clouds into a searchable analytics store, replacing manual reporting across the support organization. Data flows in through resilient Python clients for the ServiceNow Table API and the Azure and AWS cost APIs, and Elasticsearch index mappings with lifecycle management make the combined ITSM, cloud-cost and time-card data searchable.

Highlight

Built resilient Python clients for third-party APIs: a paginated ServiceNow Table API client, an Azure cost API client with exponential backoff, and an AWS cost-and-usage pipeline with retries and input validation.

  • ServiceNow API

Enterprise Cloud-Management Platform Features

Feature development on a commercial platform managing SAP and cloud workloads, spanning reporting, search, and export across a set of ticketing microservices. Deliverables included SAP HotNews and Early Watch Alert reporting with CVSS mapping and Elasticsearch aggregations, REST APIs in Express.js and Gin, and a CSV/JSON export feature shipped across five of those microservices.

Highlight

Delivered SAP HotNews and Early Watch Alert reporting with priority and CVSS mapping, Elasticsearch aggregations, and wildcard multi-value search.
