Designed and deployed a highly reliable payment automation engine handling bi-monthly recurring billing structures based on dynamic client service quotas.

• Fail-Catch Architecture: Developed a custom retry-and-recovery state machine that handles transaction drops, temporary gateway timeouts, and card issues, preventing service interruption.
• Data Pipelines: Constructed secure RESTful APIs parsing clean JSON payloads to track subscription life cycles and transaction ledgers with full mathematical precision.

Engineered automated compliance modules interfacing directly with Romanian fiscal systems (ANAF) for B2B and B2G billing ecosystems.

• Data Transformation: Developed high-performance translation layers converting legacy internal data arrays into strictly structured XML structures conforming to national electronic invoicing schemas.
• State Synchronization: Implemented cron-driven queues to poll government API endpoints, securely download zip archives, index system responses, and map validation tokens instantly to client dashboards.

Architected a fully automated, zero-touch digital signing solution for legally binding contractual documents and insurance policies.

• Security Protocols: Integrated dedicated third-party APIs (CertSign) to apply advanced digital signatures automatically upon document generation.
• Workflow Automation: Combined PDF generation microservices, secure cryptographic payloads, and instant cloud archiving to deliver signed files to end-users without manual staff intervention.

Designed a unified transactional workflow interfacing directly with PAID Romania for the mandatory issuance of residential insurance policies, later scaling the engine to handle complex optional property insurance products.

• Modular API Architecture: Engineered an extensible adapter pattern capable of transforming heterogeneous client data into specific SOAP/REST schemas required by national pool protocols.
• Validation & Error Mitigation: Implemented precise address-matching logic and real-time validation layers to catch data anomalies before hitting national insurance databases, dropping processing errors to a minimum.

Architected automated background screening and financial profiling tools for third-party corporate entities and high-value individuals.

• Financial Data Aggregation: Built multi-source API connectors targeting KeysFin and ICAP databases to dynamically scrape, normalize, and cache extensive fiscal data, balance sheets, and company risk scores.
• Compliance Verification: Integrated real-time automated PEP (Politically Exposed Persons) checks and sanction list polling to automate KYC (Know Your Customer) and AML (Anti-Money Laundering) requirements directly inside the enterprise workflow.

Designed and optimized a lightweight, high-throughput RESTful API using the Slim micro-framework to expose insurance quotation and policy issuance pipelines effortlessly to third-party partner applications.

• Complex Method Orchestration: Engineered a transactional pipeline executing up to 7 distinct, sequential method calls per single lifecycle operation—managing interdependent input/output parameters, strict status transitions, and data integrity.
• Scalability & Performance: Built a decoupled architecture capable of handling intensive daily volumes (500+ completely processed policies/day) with low latency, utilizing efficient request parsing and error mitigation strategies.

Spent over a year architecting, auditing, and refining a massive data migration and ETL strategy designed to phase out a monolithic platform built in 2001 and transition all operations to a modern ecosystem.

• Complex Schema Re-engineering: Dedicated months to reverse-engineering the legacy database structure without documentation, mapping and normalizing 20 years of continuous workload including interconnected entities (users, clients, quotations, policies, payment ledgers, and custom audit trails).
• High-Performance Execution: Engineered a single-execution PostgreSQL pipeline optimized with precise transaction batching and custom staging tables. The final automated deployment executed flawlessly in exactly 1:48:50 hours, achieving zero data loss and total referential integrity.

Architected and developed an enterprise-grade omnichannel ticketing system that has successfully processed, routed, and managed over 800,000 operational events since 2021.

• Telephony & IVR Integration: Developed custom interfaces connecting with digital private branch exchange (PBX) systems, automating ticket generation and routing based on real-time IVR (Interactive Voice Response) key-press inputs from phone calls.
• Multi-Channel Aggregation: Engineered high-availability API consumers and ingestion webhooks to unify entry channels, letting the system process tickets seamlessly whether they were created manually by agents, via external REST APIs, or through automated telephony events.

Designed and integrated an automated financial reconciliation system that processes bank statements to match incoming ledger transactions with internal invoices, policies, and premium records.

• Multi-Format Ingestion Pipelines: Built high-resiliency parsing modules handling heterogeneous data streams from banking formats including CSV, TXT, XLS, and standard SWIFT MT940 statement structures.
• Algorithmic Matching: Developed a flexible transaction-matching state machine that dynamically aligns bank settlement metadata with the core subscription and billing systems, eliminating manual financial accounting overhead.

Managed, optimized, and secured a diverse array of enterprise web properties built on monolithic content management systems, focusing on deep source-code refactoring and incident response.

• Malware Remediation & Cybersecurity: Led urgent security auditing and malware removal operations across compromised setups, tracking down malicious payloads, cleaning core source files, and implementing proactive web application firewalls (WAF).
• Full-Stack CMS Engineering: Developed custom themes, modules, and ongoing architectural enhancements from scratch for high-volume deployments across WordPress, Joomla, Drupal, and PrestaShop, maintaining backward compatibility while modernizing base infrastructure.
