Hey, I’m a senior systems and automation architect with 8+ years of experience designing, rebuilding, and operating mission-critical operational systems for growing and enterprise-level businesses. Over the last 2–3 years alone, I’ve worked directly with 150+ founders, CTOs, and executive teams, the majority based in the United States, helping them turn fragmented, messy processes into reliable, scalable systems that support real revenue and day-to-day operations. More than 90% of my work comes from US companies, including healthcare groups, legal firms, financial services, SaaS platforms, real estate operators, agencies, and professional service organizations. I’m fully accustomed to EST business hours, US decision-making styles, compliance expectations, and production-grade requirements, not experimental builds or quick hacks. What I’m Typically Brought In To Solve I’m not hired for isolated tasks. I’m brought in when systems already exist but are no longer reliable, scalable, or trusted. Common scenarios I take ownership of: CRM systems that are cluttered, inconsistently used, or structurally broken Automations that exist but fail silently, break under load, or can’t be maintained Multiple systems (CRM, Marketing, Finance, Support, Ops) that don’t sync cleanly Teams running work in spreadsheets, Slack, or inboxes because the system doesn’t enforce process Leadership lacking real-time visibility into pipeline health, SLAs, or operational risk AI or Voice initiatives that were tested but never productionised safely My role is to own the system end-to-end, stabilize it, and make it something your team can actually rely on day-to-day. Systems I Design & Own I work at the system level, not the feature level. This includes: CRM architecture with clean data models, enforced pipelines, validation rules, and role-based permissions Workflow automation layers built with deterministic logic, retries, logging, and alerting Integration backbones using APIs and webhooks for one-way and two-way sync with conflict handling Operational dashboards showing pipeline health, workload, SLA risk, and system failures Clone-ready architectures that allow teams to scale without rebuilding core logic The goal is always the same: reduce manual effort, increase reliability, and build systems that scale with the business. How I Approach Projects My approach is architecture-first, not tool-first. Before building or changing anything, I map: Source-of-truth ownership Failure modes and recovery paths Permission boundaries and data exposure Long-term maintenance cost vs short-term speed What happens when volume, users, or complexity doubles This prevents the most common failure I see in growing companies: systems that work today but collapse under growth. AI & Voice Agent (Production-Grade Only) Where it makes sense, I integrate AI and voice agents into operational workflows such as call handling, summarization, qualification, and automated follow-ups, ensuring outputs are structured, logged, auditable, and tied to core systems. I don’t ship demo or experimental AI. Everything is designed for: Production reliability Cost control Monitoring and fallback paths Secure handling of business and customer data AI is treated as infrastructure, not a novelty. If your organization needs stable, scalable systems, share a brief overview of your current setup and I'd love to help.

I'm Igor, founder and CEO of Corsac Technologies. I lead a team that modernizes legacy software that's become too risky, slow, or expensive to maintain — including systems most agencies won't touch: COBOL, Delphi, Visual Basic (VB6), ColdFusion, Oracle Forms, and FoxPro, alongside cloud migration, data migration, and application re-architecture for modern .NET and Java stacks. When you work with me, I'm your direct point of contact from scoping through delivery. I make sure the right engineers are assigned to your project, keep the technical roadmap aligned with your business priorities, and stay accountable for the outcome — so you're never chasing updates through a ticket queue or a rotating cast of account managers. What my team delivers: — Legacy language migration (COBOL, Delphi, VB6, ColdFusion, Oracle Forms, FoxPro → modern stacks) — Cloud migration and cloud-native re-architecture (AWS, Azure) — Data & database migration, including MS Access → SQL Server — Application modernization and monolith-to-microservices re-engineering — Software audits and technical due diligence — architecture, security, and scalability review — Reverse engineering of undocumented or vendor-locked systems Why teams choose to work with me: — Modernization is all we do — not a side offering alongside general dev work, so every process and hire is built around it — We integrate with your existing Git, CI/CD, and workflows instead of disrupting your team — My team includes AWS Certified Cloud Practitioner and Microsoft Azure Solutions Architect Expert engineers, and we deliver work compliant with HIPAA, SOC 2 Type II, GDPR, and PCI DSS — We run migrations in parallel environments with rollback paths, so your system stays live throughout — never a big-bang cutover — Based in Toronto, working with mid-market teams since 2018 Recent results my team delivered: reduced device setup time 60% and memory use 38% re-engineering a Windows-only GNSS monitoring app to Kotlin Multiplatform; cut code duplication 75% and cross-platform feature delivery time 80% moving a teleprompter app from fragmented native codebases to a unified multiplatform architecture; reduced hotfix release time 70% and reached full backlog visibility transforming a GIS platform's delivery process. If your system falls into the category of "nobody currently on staff fully understands how it works" — reach out. I'll personally scope a technical audit with you before any larger commitment.

I connect the tools your business runs on - CRMs, marketing platforms, Stripe, GoHighLevel, Klaviyo, internal databases - and increasingly, I wire AI into them: agents, RAG, and LLM automation that work in production. Most AI features don't fail at the model. They fail at the integration layer: half-documented APIs, rate limits, stale and duplicate data, retrieval that returns confident nonsense. That layer is what I've built for 7+ years across 37 Upwork contracts at 100% Job Success - one client put it as "the quality of his architecture and code is top 5%." WHAT I BUILD - API integrations and automations - the work most of my reviews are about. CRMs (GoHighLevel, HubSpot, CollaborateMD), marketing and ads data (Klaviyo, Facebook Ads, TikTok, Impact Radius), payments, e-commerce, internal systems. Python, REST, webhooks, n8n. - AI agents and LLM workflows - tool-calling against real business APIs with retries, guardrails, and human-in-the-loop checkpoints. LangGraph, LangChain, MCP, OpenAI, Claude. - RAG systems - chunking and embedding strategy, hybrid search, citation-backed answers, and eval harnesses so accuracy is measured, not hoped for. Pinecone, Qdrant, pgvector. - Data pipelines and backend infrastructure - ETL (custom and Airbyte), ingestion, scraping, normalization, deployed on AWS (ECS Fargate, Celery, WebSockets) as infrastructure-as-code. One of my pipelines handled millions of records and ran 18 months and 573 hours for the same client because it kept working. RECENT WORK Parse - AI analytics platform where autonomous agents audit a company's SaaS stack (Stripe, HubSpot, Jira) for revenue leakage and churn signals, no SQL needed. As founding engineer I built it end to end: AWS infrastructure as code, LangChain analysis pipelines, RAG chat, and 30+ SaaS connectors. Live product; link in my Portfolio below. AftermarketScout - live inventory and pricing pulled from multiple distributor portals into one search interface for auto repair shops. Live product; link in my Portfolio below. TRACK RECORD Top Rated. 100% Job Success across 37 contracts and 870+ hours. Clients repeatedly flag the same three things: reliable, clear communicator, committed to quality. I respond within 4 hours. HOW I WORK Send the use case. Within 4 hours you get an honest feasibility read - including whether you actually need an LLM for it, because sometimes a plain integration is cheaper and better. Then a scoped plan with a small fixed first milestone, so you're never buying a black box. MSc, Computer and Information Science - University of Ljubljana.

I build Power BI and Microsoft Fabric reporting for operations and finance teams star-schema models, optimized DAX, and pipelines that don't break. Most of my work starts the same way: a business is running on a dozen Excel files, three people maintain them by hand, and nobody fully trusts the numbers in the Monday meeting. I consolidate the sources, build a proper dimensional model underneath, and deliver reports leadership actually opens. RECENT WORK Rebuilt a fragmented multi-source Excel reporting stack into a single Power BI model scoped, built, and delivered in one day. 5-star review. Cut report generation time roughly 90% on a sales dashboard by reworking the data model and rewriting the DAX behind the slow visuals. Diagnosed a broken ETL pipeline where loads were silently dropping rows, then rebuilt it with validation so the failure couldn't repeat quietly. WHAT I DO Power BI report and dashboard development Data modeling — star schema, relationships, row-level security DAX measures, calculation groups, and performance tuning Microsoft Fabric — Lakehouse, Warehouse, Pipelines SQL Server, Azure SQL, and Azure Data Factory ETL/ELT Power Query and Excel-to-BI migrations Dataset optimization, refresh failures, and report performance audits BACKGROUND I'm a Senior BI Developer at Avanceon, delivering enterprise reporting for GCC oil & gas, manufacturing, and logistics clients — SAP and SQL Server sources, Azure Data Factory pipelines, and C-suite dashboards built under strict data governance. Before that I built Power BI solutions remotely for UK healthcare and operations clients. That's the standard I bring here, whether the contract is $200 or $5,000. HOW I WORK I ask questions before I quote — usually about where your data actually lives, how often it needs to refresh, and who's going to open the report. You'll get a scoped plan, a fixed price wherever the scope allows one, and a short update at the end of every working day. I reply within four hours during business hours and overlap comfortably with European mornings and US mornings. ALSO AVAILABLE AI-assisted reporting workflows — n8n automations, OpenAI-generated summaries, and conversational query layers built on top of an existing BI model. Worth asking about if it's relevant to your project, though the reporting foundation always comes first. START HERE If you have a Power BI report that's slow, wrong, or that nobody opens — send me the PBIX or a screenshot of the model view. I'll tell you what's wrong with it before you pay me anything.
